The word for “blood” in the Bible is used both literally and metaphorically. “Blood” is a significant biblical term for understanding purity boundaries and theological concepts. Blood is a dominant ritual symbol in biblical literature. Blood was used in sacrifices and purification rites, and it was inherently connected to menstruation, animal slaughter, and legal culpability. Among the physical properties of blood are the ability to coagulate, the liquid state of the substance (Rev. 16:3 4), and the ability to stain (Rev. 19:13). Blood can symbolize moral order in terms of cult, law, and power.

The usage of blood in the OT is predominantly negative. The first direct mention of blood in the biblical text involves a homicide (Gen. 4:10). Henceforward, the shedding of human blood is a main concern (Gen. 9:6). Other concerns pertaining to blood include dietary prohibitions of blood (Lev. 17:10–12), purity issues such as the flow of blood as in menstrual blood (Lev. 15:19–24), and blood as a part of religious rites such as circumcision (Gen. 17:10–11; Exod. 4:24–26).

Leviticus 17:11 contains a central statement in the OT concerning the significant role of blood in the sacrificial system: “The life of a creature is in the blood.” Blood was collected from all animal sacrifices, and blood was poured onto the altar (Lev. 1:5).

The covenant with Abraham was sealed with a covenantal ritual (Gen. 15:10–21). Moses sealed the covenant between the Israelites and God with a blood ritual during which young Israelite men offered young bulls among other sacrifices as fellowship offerings (Exod. 24:5). Moses read the words of the Book of the Covenant and sprinkled the blood of the bulls on the people, saying, “This is the blood of the covenant that the Lord has made with you in accordance with all these words” (Exod. 24:7–8).

During the Passover observance at the time of the exodus, blood was placed on the sides and tops of the doorframes of the Hebrews (Exod. 12:7). Not only altars were sprinkled and thus consecrated with blood, but priests were as well. Aaron and his sons were consecrated by the application of blood to their right earlobe, thumb, and big toe, and the sprinkling of blood and oil on their garments (Exod. 29:20). On the Day of Atonement, the high priest entered the holy of holies and sprinkled blood on the mercy seat to seek atonement for the sins of the people (Lev. 16:15).

Many events in the passion of Christ include references to blood. During the Last Supper, Jesus redefined the last Passover cup: “This is my blood of the covenant, which is poured out for many for the forgiveness of sins” (Matt. 26:28). Judas betrayed “innocent blood” (Matt. 27:4), and the money he received for his betrayal was referred to as “blood money” (Matt. 27:6). At Jesus’ trial, Pilate washed his hands and declared, “I am innocent of this man’s blood” (Matt. 27:24).

The apostle Paul wrote that believers are justified by the blood of Christ (Rom. 5:9). This justification or righteous standing with God was effected through Christ’s blood sacrifice (Rom. 3:25–26; 5:8). The writer of Hebrews stressed the instrumental role of blood in bringing about forgiveness (Heb. 9:22). In the picture of the ideal community of Christ, the martyrs in the book of Revelation are situated closest to the throne of God because “they triumphed over him [Satan] by the blood of the Lamb and by the word of their testimony; they did not love their lives so much as to shrink from death” (Rev. 12:11). The blood of the Lamb, Christ, is the effective agent here and throughout the NT, bringing about the indirect contact between sinner and God.

In the OT, heavenly beings or angels are sometimes referred to as “sons of God” (Gen. 6:2; Job 1:6; 2:1; 38:7; Pss. 82:6; 89:6). The more important background for the NT, however, is the use of the term with reference to the nation Israel and the messianic king from David’s line. Israel was God’s son by virtue of God’s unique calling, deliverance, and protection. Hosea 11:1 reads, “When Israel was a child, I loved him, and out of Egypt I called my son.” Similar references to God as the father of his people appear throughout the OT (Exod. 4:22; Num. 11:12; Deut. 14:1; 32:5, 19; Isa. 43:6; 45:11; Jer. 3:4, 19; 31:9, 20; Hos. 2:1). The king from the line of David is referred to as the son of God by virtue of his special relationship to God and his representative role among the people. In the Davidic covenant, God promises David concerning his descendant, “I will be his father, and he will be my son” (2 Sam. 7:14; cf. Pss. 2:7; 89:26). Later Judaism appears to have taken up these passages and identified the coming Messiah as the “son of God.”

The founder of what became known as the movement of Jesus followers or Christianity. For Christian believers, Jesus Christ embodies the personal and supernatural intervention of God in human history.

Birth and childhood. The Gospels of Matthew and Luke record Jesus’ birth in Bethlehem during the reign of Herod the Great (Matt. 2:1; Luke 2:4, 11). Jesus was probably born between 6 and 4 BC, shortly before Herod’s death (Matt. 2:19). Both Matthew and Luke record the miracle of a virginal conception made possible by the Holy Spirit (Matt. 1:18; Luke 1:35). Luke mentions a census under the Syrian governor Quirinius that was responsible for Jesus’ birth taking place in Bethlehem (2:1 5). Both the census and the governorship at the time of the birth of Jesus have been questioned by scholars. Unfortunately, there is not enough extrabiblical evidence to either confirm or disprove these events, so their veracity must be determined on the basis of one’s view regarding the general reliability of the Gospel tradition.

On the eighth day after his birth, Jesus was circumcised, in keeping with the Jewish law, at which time he officially was named “Jesus” (Luke 2:21). He spent his growing years in Nazareth, in the home of his parents, Joseph and Mary (2:40). Of the NT Gospels, the Gospel of Luke contains the only brief portrayal of Jesus’ growth in strength, wisdom, and favor with God and people (2:40, 52). Luke also contains the only account of Jesus as a young boy (2:41–49).

Baptism, temptation, and start of ministry. After Jesus was baptized by the prophet John the Baptist (Luke 3:21–22), God affirmed his pleasure with him by referring to him as his Son, whom he loved (Matt. 3:17; Mark 1:11; Luke 3:22). Jesus’ baptism did not launch him into fame and instant ministry success; instead, Jesus was led by the Spirit into the wilderness, where he was tempted for forty days (Matt. 4:1–11; Mark 1:12–13; Luke 4:1–13). Mark stresses that the temptations immediately followed the baptism. Matthew and Luke identify three specific temptations by the devil, though their order for the last two is reversed. Both Matthew and Luke agree that Jesus was tempted to turn stones into bread, expect divine intervention after jumping off the temple portico, and receive all the world’s kingdoms for worshiping the devil. Jesus resisted all temptation, quoting Scripture in response.

Matthew and Mark record that Jesus began his ministry in Capernaum in Galilee, after the arrest of John the Baptist (Matt. 4:12–13; Mark 1:14). Luke says that Jesus started his ministry at about thirty years of age (3:23). This may be meant to indicate full maturity or perhaps correlate this age with the onset of the service of the Levites in the temple (cf. Num. 4:3). John narrates the beginning of Jesus’ ministry by focusing on the calling of the disciples and the sign performed at a wedding at Cana (1:35–2:11).

Galilean ministry. The early stages of Jesus’ ministry centered in and around Galilee. Jesus presented the good news and proclaimed that the kingdom of God was near. Matthew focuses on the fulfillment of prophecy (Matt. 4:13–17). Luke records Jesus’ first teaching in his hometown, Nazareth, as paradigmatic (Luke 4:16–30); the text that Jesus quoted, Isa. 61:1–2, set the stage for his calling to serve and revealed a trajectory of rejection and suffering.

All the Gospels record Jesus’ gathering of disciples early in his Galilean ministry (Matt. 4:18–22; Mark 1:16–20; Luke 5:1–11; John 1:35–51). The formal call and commissioning of the Twelve who would become Jesus’ closest followers is recorded in different parts of the Gospels (Matt. 10:1–4; Mark 3:13–19; Luke 6:12–16). A key event in the early ministry is the Sermon on the Mount/Plain (Matt. 5:1–7:29; Luke 6:20–49). John focuses on Jesus’ signs and miracles, in particular in the early parts of his ministry, whereas the Synoptics focus on healings and exorcisms.

During Jesus’ Galilean ministry, onlookers struggled with his identity. However, evil spirits knew him to be of supreme authority (Mark 3:11). Jesus was criticized by outsiders and by his own family (3:21). The scribes from Jerusalem identified him as a partner of Beelzebul (3:22). Amid these situations of social conflict, Jesus told parables that couched his ministry in the context of a growing kingdom of God. This kingdom would miraculously spring from humble beginnings (4:1–32).

The Synoptics present Jesus’ early Galilean ministry as successful. No challenge or ministry need superseded Jesus’ authority or ability: he calmed a storm (Mark 4:35–39), exorcized many demons (5:1–13), raised the dead (5:35–42), fed five thousand (6:30–44), and walked on water (6:48–49).

In the later part of his ministry in Galilee, Jesus often withdrew and traveled to the north and the east. The Gospel narratives are not written with a focus on chronology. However, only brief returns to Galilee appear to have taken place prior to Jesus’ journey to Jerusalem. As people followed Jesus, faith was praised and fear resolved. Jerusalem’s religious leaders traveled to Galilee, where they leveled accusations and charged Jesus’ disciples with lacking ritual purity (Mark 7:1–5). Jesus shamed the Pharisees by pointing out their dishonorable treatment of parents (7:11–13). The Pharisees challenged his legitimacy by demanding a sign (8:11). Jesus refused them signs but agreed with Peter, who confessed, “You are the Messiah” (8:29). Jesus did provide the disciples a sign: his transfiguration (9:2–8).

Jesus withdrew from Galilee to Tyre and Sidon, where a Syrophoenician woman requested healing for her daughter. Jesus replied, “I was sent only to the lost sheep of Israel” (Matt. 15:24). Galileans had long resented the Syrian provincial leadership partiality that allotted governmental funds in ways that made the Jews receive mere “crumbs.” Consequently, when the woman replied, “Even the dogs eat the crumbs that fall from their master’s table,” Jesus applauded her faith (Matt. 15:27–28). Healing a deaf-mute man in the Decapolis provided another example of Jesus’ ministry in Gentile territory (Mark 7:31–37). Peter’s confession of Jesus as the Christ took place during Jesus’ travel to Caesarea Philippi, a well-known Gentile territory. The city was the ancient center of worship of the Hellenistic god Pan.

Judean ministry. Luke records a geographic turning point in Jesus’ ministry as he resolutely set out for Jerusalem, a direction that eventually led to his death (Luke 9:51). Luke divides the journey to Jerusalem into three phases (9:51–13:21; 13:22–17:10; 17:11–19:27). The opening verses of phase one emphasize a prophetic element of the journey. Jesus viewed his ministry in Jerusalem as his mission, and the demands on discipleship intensified as Jesus approached Jerusalem (Matt. 20:17–19, 26–28; Mark 10:38–39, 43–45; Luke 14:25–35). Luke presents the second phase of the journey toward Jerusalem with a focus on conversations regarding salvation and judgment (Luke 13:22–30). In the third and final phase of the journey, the advent of the kingdom and the final judgment are the main themes (17:20–37; 19:11–27).

Social conflicts with religious leaders increased throughout Jesus’ ministry. These conflicts led to lively challenge-riposte interactions concerning the Pharisaic schools of Shammai and Hillel (Matt. 19:1–12; Mark 10:1–12). Likewise, socioeconomic feathers were ruffled as Jesus welcomed young children, who had little value in society (Matt. 19:13–15; Mark 10:13–16; Luke 18:15–17).

Passion week, death, and resurrection. Each of the Gospels records Jesus’ entry into Jerusalem with the crowds extending him a royal welcome (Matt. 21:4–9; Mark 11:7–10; Luke 19:35–38; John 12:12–15). Luke describes Jesus’ ministry in Jerusalem as a time during which Jesus taught in the temple as Israel’s Messiah (19:45–21:38).

In Jerusalem, Jesus cleansed the temple of profiteering (Mark 11:15–17). Mark describes the religious leaders as fearing Jesus because the whole crowd was amazed at his teaching, and so they “began looking for a way to kill him” (11:18). Dismayed, each segment of Jerusalem’s temple leadership inquired about Jesus’ authority (11:27–33). Jesus replied with cunning questions (12:16, 35–36), stories (12:1–12), denunciation (12:38–44), and a prediction of Jerusalem’s own destruction (13:1–31). One of Jesus’ own disciples, Judas Iscariot, provided the temple leaders the opportunity for Jesus’ arrest (14:10–11).

At the Last Supper, Jesus instituted a new Passover, defining a new covenant grounded in his sufferings (Matt. 26:17–18, 26–29; Mark 14:16–25; Luke 22:14–20). He again warned the disciples of his betrayal and arrest (Matt. 26:21–25, 31; Mark 14:27–31; Luke 22:21–23; John 13:21–30), and later he prayed for the disciples (John 17:1–26) and prayed in agony and submissiveness in the garden of Gethsemane (Matt. 26:36–42; Mark 14:32–42; Luke 22:39–42). His arrest, trial, crucifixion, death, and resurrection followed (Matt. 26:46–28:15; Mark 14:43–16:8; Luke 22:47–24:9; John 18:1–20:18). Jesus finally commissioned his disciples to continue his mission by making disciples of all the nations (Matt. 28:18–20; Acts 1:8) and ascended to heaven with the promise that he will one day return (Luke 24:50–53; Acts 1:9–11).

Israel shared the cosmology of its ancient Near Eastern neighbors. This worldview understood the earth as a “disk” upon the primeval waters (Job 38:13; Isa. 40:22), with the earth having four rims or “corners” (Ps. 135:7; Isa. 11:12). These rims were sealed at the horizon to prevent the influx of cosmic waters. God speaks to Job about the dawn grasping the edges of the earth and shaking the evil people out of it (Job 38:12 13).

Israel’s promised land was built on the sanctuary prototype of Eden (Gen. 13:10; Deut. 6:3; 31:20); both were defined by divine blessing, fertility, legal instruction, secure boundaries, and were orienting points for the world. Canaan was Israel’s new paradise, “flowing with milk and honey” (Exod. 3:8; Num. 13:27). Conversely, the lack of fertile land was tantamount to insecurity and judgment. As Eden illustrated for Israel, any rupture of relationship with God brought alienation between humans, God, and the land; this could ultimately bring exile, as an ethically nauseated land “vomits” people out (Lev. 18:25, 28; 20:22; see also Deut. 4; 30).

For Israel, land involved both God’s covenant promise (Gen. 15:18–21; 35:9–12) and the nation’s faithful obedience (Gen. 17:1; Exod. 19:5; 1 Kings 2:1–4). Yahweh was the earth’s Lord (Ps. 97:5), Judge (Gen. 18:25), and King (Ps. 47:2, 7). Both owner and giver, he was the supreme landlord, who gifted the land to Israel (Exod. 19:5; Lev. 25:23; Josh. 22:19; Ps. 24:1). The land was God’s “inheritance” to give (1 Sam. 26:19; 2 Sam. 14:16; Ps. 79:1; Jer. 2:7). The Levites, however, did not receive an allotment of land as did the other tribes, since God was their “portion” (Num. 18:20; Ps. 73:26). Israel’s obedience was necessary both to enter and to occupy the land (Deut. 8:1–3; 11:8–9; 21:1; 27:1–3). Ironically, the earth swallowed rebellious Israelites when they accused Moses of bringing them “up out of a land flowing with milk and honey” (Num. 16:13). As the conquest shows, however, no tribe was completely obedient, taking its full “inheritance” (Josh. 13:1).

Faith in the context of the OT rests on a foundation that the person or object of trust, belief, or confidence is reliable. Trust in Yahweh is expressed through loyalty and obedience. The theme of responsive obedience is emphasized in the Torah (Exod. 19:5). In the later history of Israel, faithfulness to the law became the predominant expression of faith (Dan. 1:8; 6:10). OT faith, then, is a moral response rather than abstract intellect or emotion.

Faith is a central theological concept in the NT. In relational terms, faith is foremost personalized as the locus of trust and belief in the person of Jesus Christ.

In the Gospels, Jesus is spoken of not as the subject of faith (as believing in God), but as the object of faith. In the Synoptic Gospels, faith is seen most often in connection with the ministry of Jesus. Miracles, in particular healings, are presented as taking place in response to the faith of the one in need of healing or the requester. In the Gospel of John, faith (belief) is presented as something that God requires of his people (6:28 29).

In the book of Acts, “faith/belief” is used to refer to Jews and Gentiles converting to following the life and teachings of Jesus Christ and becoming part of the Christian community. The book correlates faith in Christ closely with repentance (Acts 11:21; 19:18; 20:21; 26:18).

Paul relates faith to righteousness and justification (Rom. 3:22; 5:11; Gal. 3:6). In Ephesians faith is shown as instrumental in salvation: “For it is by grace you have been saved, through faith—and this not from yourselves, it is the gift of God” (2:8).

In Hebrews, faith is described as “being sure of what we hope for and certain of what we do not see” (11:1). Faith thus is viewed as something that can be accomplished in the life of the believer—a calling of God not yet tangible or seen. To possess faith is to be loyal to God and to the gospel of Jesus Christ despite all obstacles. In the Letter of James, genuine works naturally accompany genuine faith. Works, however, are expressed in doing the will of God. The will of God means, for example, caring for the poor (James 2:15–16).

In 1 Peter, Christ is depicted as the broker of faith in God (1:21), whereas in 2 Peter and Jude faith is presented as received from God (2 Pet. 1:1). In the Letters of John “to believe” is used as a litmus test for those who possess eternal life: “You who believe in the name of the Son of God, . . . you have eternal life” (1 John 5:13).

People in the Bible were family-centered and staunchly loyal to their kin. Families formed the foundation of society. The extended family was the source of people’s status in the community and provided the primary economic, educational, religious, and social interactions.

Marriage and divorce. Marriage in the ancient Near East was a contractual arrangement between two families, arranged by the bride’s father or a male representative. The bride’s family was paid a dowry, a “bride’s price.” Paying a dowry was not only an economic transaction but also an expression of family honor. Only the rich could afford multiple dowries. Thus, polygamy was minimal. The wedding itself was celebrated with a feast provided by the father of the groom.

The primary purpose for marriage in the ancient Near East was to produce a male heir to ensure care for the couple in their old age. The concept of inheritance was a key part of the marriage customs, especially with regard to passing along possessions and property.

Marriage among Jews in the NT era still tended to be endogamous; that is, Jews sought to marry close kin without committing incest violations (Lev. 18:6 17). A Jewish male certainly was expected to marry a Jew. Exogamy, marrying outside the remote kinship group, and certainly outside the ethnos, was understood as shaming God’s holiness. Thus, a Jew marrying a Gentile woman was not an option. The Romans did practice exogamy. For them, marrying outside one’s kinship group (not ethnos) was based predominantly on creating strategic alliances between families.

Greek and Roman law allowed both men and women to initiate divorce. In Jewish marriages, only the husband could initiate divorce proceedings. If a husband divorced his wife, he had to release her and repay the dowry. Divorce was common in cases of infertility (in particular if the woman had not provided male offspring). Ben Sira comments that barrenness in a woman is a cause of anxiety to the father (Sir. 42:9–10). Another reason for divorce was adultery (Exod. 20:14; Deut. 5:18). Jesus, though, taught a more restrictive use of divorce than the OT (Mark 10:1–12).

Children and parenting. Childbearing was considered representative of God’s blessing on a woman and her entire family, in particular her husband. In contrast to this blessing, barrenness brought shame on women, their families, and specifically their husbands.

Children were of low social status in society. Infant mortality was high. An estimated 60 percent of the children in the first-century Mediterranean society were dead by the age of sixteen.

Ancient Near Eastern and Mediterranean societies exhibited a parenting style based on their view of human nature as a mixture of good and evil tendencies. Parents relied on physical punishment to prevent evil tendencies from developing into evil deeds (Prov. 29:15). The main concern of parents was to socialize the children into family loyalty. Lack of such loyalty was punished (Lev. 20:9). At a very early stage children were taught to accept the total authority of the father. The rearing of girls was entirely the responsibility of the women. Girls were taught domestic roles and duties as soon as possible so that they could help with household tasks.

Family identity was used as a metaphor in ancient Israel to speak of fidelity, responsibility, judgment, and reconciliation. In the OT, the people of Israel often are described as children of God. In their overall relationship to God, the people of Israel are referred to in familial terms—sons and daughters, spouse, and firstborn (Exod. 4:22). God is addressed as the father of the people (Isa. 63:16; 64:8) and referred to as their mother (Isa. 49:14–17).

The church as the family of God. Throughout his ministry, Jesus called his disciples to follow him. This was a call to loyalty (Matt. 10:32–40; 16:24–26; Mark 8:34–38; Luke 9:23–26), a call to fictive kinship, the family of God (Matt. 12:48–50; Mark 3:33–35). Jesus’ declaration “On this rock I will build my church” (Matt. 16:18) was preceded by the call to community. Entrance into the community was granted through adopting the values of the kingdom, belief, and the initiation rite of baptism (Matt. 10:37–39; 16:24–26; Mark 8:34–38; Luke 9:23–26, 57–63; John 1:12; 3:16; 10:27–29; Acts 2:38; 16:31–33; 17:30; Rom. 10:9). Jesus’ presence as the head of the community was eventually replaced by the promised Spirit (John 14:16–18). Through the Spirit, Jesus’ ministry continues in the community of his followers, God’s family—the church. See also Adoption.

Physiologically, the heart is an organ in the body, and in the Bible it is also used in a number of metaphors.

Metaphorically, the heart refers to the mind, the will, the seat of emotions, or even the whole person. It also refers to the center of something or its inner part. These metaphors come from the heart’s importance and location.

Mind. The heart refers to the mind, but not the brain, and in these cases does not involve human physiology. It is a metaphor, and while the neurophysiology of the heart may be interesting in its own right, it has no bearing on this use of language. Deuteronomy 6:5 issues the command to love God with all one’s heart, soul, and strength. When the command is repeated in the Gospels, it occurs in three variations (Matt. 22:37; Mark 12:30; Luke 10:27). Common to all three is the addition of the word “mind.” The Gospel writers want to be sure that the audience hears Jesus adding “mind,” but this addition is based on the fact that the meaning of the Hebrew word for “heart” includes the mind.

The mental activities of the metaphorical heart are abundant. The heart is where a person thinks (Gen. 6:5; Deut. 7:17; 1 Chron. 29:18; Rev. 18:7), where a person comprehends and has understanding (1 Kings 3:9; Job 17:4; Ps. 49:3; Prov. 14:13; Matt. 13:15). The heart makes plans and has intentions (Gen. 6:5; 8:21; Prov. 20:5; 1 Chron. 29:18; Jer. 23:20). One believes with the heart (Luke 24:25; Acts 8:37; Rom. 10:9). The heart is the site of wisdom, discernment, and skill (Exod. 35:34; 36:2; 1 Kings 3:9; 10:24). The heart is the place of memory (Deut. 4:9; Ps. 119:11). The heart plays the role of conscience (2 Sam. 24:10; 1 John 3:20 21).

It is often worth the effort to substitute “mind” for “heart” when reading the Bible in order to grasp the mental dimension. For example, after telling the Israelites to love God with all their heart, Moses says, “These commandments that I give you today are to be upon your hearts” (Deut. 6:6). Reading it instead as “be on your mind” changes our perspective, and in this case the idiom “on your mind” is clearer and more accurate. The following verses instruct parents to talk to their children throughout the day about God’s words. In order for parents to do this, God’s requirements and deeds need to be constantly on their minds, out of their love for him. Similarly, love for God and loyalty are expressed by meditation on and determination to obey his law (Ps. 119:11, 112). The law is not merely a list of rules; it is also a repository of a worldview in which the Lord is the only God. To live consistently with this truth requires careful, reflective thought.

Emotions and attitude. The heart, as the seat of emotion, is associated with a number of feelings and sentiments, such as gladness (Exod. 4:14; Acts 2:26), hatred (Lev. 19:17), pride (Deut. 8:14), resentment (Deut. 15:10), dread (Deut. 28:67), sympathy (Judg. 5:9), love (Judg. 16:15), sadness (1 Sam. 1:8; John 16:6), and jealousy and ambition (James 3:14). The heart is also the frame of reference for attitudes such as willingness, courage, and desire.

The present abode of God and the final dwelling place of the righteous. The ancient Jews distinguished three different heavens. The first heaven was the atmospheric heavens of the clouds and where the birds fly (Gen. 1:20). The second heaven was the celestial heavens of the sun, the moon, and the stars. The third heaven was the present home of God and the angels. Paul builds on this understanding of a third heaven in 2 Cor. 12:2 4, where he describes himself as a man who “was caught up to the third heaven” or “paradise,” where he “heard inexpressible things.” This idea of multiple heavens also shows itself in how the Jews normally spoke of “heavens” in the plural (Gen. 1:1), while most other ancient cultures spoke of “heaven” in the singular.

Although God is present everywhere, God is also present in a special way in “heaven.” During Jesus’ earthly ministry, the Father is sometimes described as speaking in “a voice from heaven” (Matt. 3:17). Similarly, Jesus instructs us to address our prayers to “Our Father in heaven” (6:9). Even the specific request in the Lord’s Prayer that “your kingdom come, your will be done, on earth as it is in heaven” (6:10) reminds us that heaven is a place already under God’s full jurisdiction, where his will is presently being done completely and perfectly. Jesus also warns of the dangers of despising “one of these little ones,” because “their angels in heaven always see the face of my Father in heaven” (18:10). Jesus “came down from heaven” (John 6:51) for his earthly ministry, and after his death and resurrection, he ascended back “into heaven,” from where he “will come back in the same way you have seen him go into heaven” (Acts 1:11).

Given this strong connection between heaven and God’s presence, there is a natural connection in Scripture between heaven and the ultimate hope of believers. Believers are promised a reward in heaven (“Rejoice and be glad, because great is your reward in heaven” [Matt. 5:12]), and even now believers can “store up for [themselves] treasures in heaven” (6:20). Even in this present life, “our citizenship is in heaven” (Phil. 3:20), and our hope at death is to “depart and be with Christ, which is better by far” (1:23). Since Christ is currently in heaven, deceased believers are already present with Christ in heaven awaiting his return, when “God will bring with Jesus those who have fallen asleep in him” (1 Thess. 4:14).

Holiness is an attribute of God and of all that is fit for association with him. God alone is intrinsically holy (Rev. 15:4). God the Father is holy (John 17:11), as is the Son (Acts 3:14), while “Holy” is the characteristic designation of God’s Spirit (Ps. 51:11; Matt. 1:18). God’s name is holy (Luke 1:49), as are his arm (Ps. 98:1), ways (Ps. 77:13), and words (Ps. 105:42).

With reference to God himself, holiness may indicate something like his uniqueness, and it is associated with attributes such as his glory (Isa. 6:3), righteousness (Isa. 5:16), and jealousy—that is, his proper concern for his reputation (Josh. 24:19).

God’s dwelling place is in heaven (Ps. 20:6), and “holy” functions in some contexts as a virtual equivalent for heavenly (11:4). God’s throne is holy (47:8), and the angels who surround it are “holy ones” (89:5; cf. Mark 8:38).

A corollary of God’s holiness is that he must be treated as holy (Lev. 22:32)—that is, honored (Lev. 10:3), worshiped (Ps. 96:9), and feared (Isa. 8:13).

While “holy” is sometimes said to mean “set apart,” this does not appear to be its core meaning, though it is an associated notion (Lev. 20:26; Heb. 7:26). Holiness, as applied to people and things, is a relational concept. They are (explicitly or implicitly) holy “to the Lord” (Exod. 28:36), never “from” something.

The symbolic representation of God’s heavenly palace, the tabernacle (Exod. 40:9), and later the temple (1 Chron. 29:3), and everything associated with them, are holy and the means whereby God’s people in the OT may symbolically be brought near to God. For God to share his presence with anything or anyone else, these too must be holy (Lev. 11:44 45; Heb. 12:14).

The OT system of worship involved the distinction between unclean and clean, and between common and holy, and the means of effecting a transition to a state of cleanness or holiness (Lev. 10:10). People, places, and items may be made holy by a process of consecration or sanctification, whether simply by God’s purifying presence (Exod. 3:5) or by ritual acts (Exod. 19:10; 29:36).

God’s faithful people are described as holy (Exod. 19:6; 1 Pet. 2:9). In the OT, this is true of the whole people of God at one level, and of particular individuals at another. Thus, kings (Ps. 16:10), prophets (2 Kings 4:9), and in particular priests (Lev. 21:7) are declared to be holy. While the OT witnesses to some tension between the collective holiness of Israel and the particular holiness of its designated leaders (Num. 16:3), the latter were intended to act as models and facilitators of Israel’s holiness.

For Christians, God is the creator of the cosmos and the redeemer of humanity. He has revealed himself in historical acts—namely, in creation, in the history of Israel, and especially in the person and work of Jesus Christ. There is only one God (Deut. 6:4); “there is no other” (Isa. 45:5). Because “God is spirit” (John 4:24), he must reveal himself through various images and metaphors.

The OT refers to God by many names. One of the general terms used for God, ’el (which probably means “ultimate supremacy”), often appears in a compound form with a qualifying word, as in ’el ’elyon (“God Most High”), ’el shadday (“God Almighty”), and ’el ro’i (“the God who sees me” or “God of my seeing”). These descriptive names reveal important attributes of God and usually were derived from the personal experiences of the people of God in real-life settings; thus, they do not describe an abstract concept of God.

The most prominent personal name of God is yahweh (YHWH), which is translated as “the Lord” in most English Bibles. At the burning bush in the wilderness of Horeb, God first revealed to Moses his personal name in sentence form: “I am who I am” (Exod. 3:13 15). Though debated, the divine name “YHWH” seems to originate from an abbreviated form of this sentence. Yahweh, who was with Moses and his people at the time of exodus, is the God who was with Abraham, Isaac, and Jacob. According to Jesus’ testimony, “the God of Abraham, the God of Isaac, and the God of Jacob” is identified as the God “of the living” (Matt. 22:32). Hence, the name “Yahweh” is closely tied to God’s self-revelation as the God of presence and life.

Many of God’s attributes are summarized in Exod. 34:6–7: “The Lord, the Lord, the compassionate and gracious God, slow to anger, abounding in love and faithfulness, maintaining love to thousands, and forgiving wickedness, rebellion and sin. Yet he does not leave the guilty unpunished; he punishes the children and their children for the sin of the parents to the third and fourth generation.”

The Christian God of the Bible is the triune God. God is one but exists in three persons: the Father, the Son, and the Holy Spirit (Matt. 28:19). The Son is one with the Father (John 10:30); the Holy Spirit is one with God (2 Sam. 23:2–3). All three share the same divine nature; they are all-knowing, holy, glorious, and called “Lord” and “God” (Matt. 11:25; John 1:1; 20:28; Acts 3:22; 5:3–4; 10:36; 1 Cor. 8:6; 2 Cor. 3:17–18; 2 Pet. 1:1). All three share in the same work of creation (Gen. 1:1–3), salvation (1 Pet. 1:2), indwelling (John 14:23), and directing the church’s mission (Matt. 28:18–20; Acts 16:6–10; 14:27; 13:2–4).

The Bible uses the metaphor of marriage to describe God’s covenant relationship with his people (Isa. 54:5 8). This metaphor captures the intimate character of the relationship that God desires to have with his people. Marriage is the most intimate human relationship in two ways. First, marriage is a relationship in which knowledge is the most intimate. A spouse can see many of the flaws that are hidden from others. Thus, each spouse must accept and love the other for who that person is, in spite of his or her imperfections. Second, the depth and passion of the expressions of love are most intimate in marriage. Consequently, there is no greater pain than that caused by unfaithfulness to this covenant.

Sadly, as the story of the OT unfolds, God’s “wife” betrays him. How so? His people worship idols in their hearts (Ezek. 14:1–5). Because God is jealous for the exclusive love of his people, idolatry is spiritual unfaithfulness. God wants both the allegiance and the affection of their hearts to be reserved exclusively for him. The people continue the formalities of worship, but their hearts have turned away from God. The book of Hosea illustrates the sense of betrayal that God feels when his people are spiritually unfaithful. God tells Hosea to marry a woman who will be unfaithful to him. Subsequently, she leaves Hosea for one lover after another. This story is intended to give God’s people a vivid picture of how painful their spiritual betrayal of him is. His heart is crushed by the rebellious and idolatrous condition of his people. Hosea’s wife ends up on the market as a prostitute, and God tells him to buy her back and love her again.

The story of God’s love for his people is expanded by what the Father did centuries later when he sent Jesus to pay the ransom for the sins of his people so that they might be healed of their rebellion and receive eternal life (John 3:16; 17:24). The death and resurrection of Christ were necessary because sin had to be atoned for. This love is a free gift that comes to the one who trusts in Christ for forgiveness of sin and a new heart. The new heart inclines one to please God. The gift of the Spirit enables one to bear the “fruit” of love (Gal. 5:22–23). As Abraham’s engrafted children (Gal. 3:7), believers are called by God to live as pilgrims on their way to a heavenly promised land (Heb. 11:9–10; 1 Pet. 2:11).

Christ modeled genuine love by serving us (Mark 10:42–45). His love should motivate us and enable us to practice sacrificial service toward others (Matt. 22:39; 1 John 3:16). It should also cause us to practice forbearance, long-suffering, and forgiveness toward those who wrong us (Matt. 18:21–35). It should cause us to repay evil with good (Rom. 12:14). Our love for truth should motivate us to act in the best interests of others (1 Cor. 13:4–8) in the hope that they may become reconciled to God (2 Tim. 2:24–26).

In the world of the Bible, a person was viewed as a unity of being with the pervading breath and thus imprint of the loving and holy God. The divine-human relationship consequently is portrayed in the Bible as predominantly spiritual in nature. God is spirit, and humankind may communicate with him in the spiritual realm. The ancients believed in an invisible world of spirits that held most, if not all, reasons for natural events and human actions in the visible world.

The OT writers used the common Hebrew word ruakh (“wind” or “breath”) to describe force and even life from the God of the universe. In its most revealing first instance, God’s ruakh hovered above the waters of the uncreated world (Gen. 1:2). In the next chapter of Genesis a companion word, neshamah (“breath”), is used as God breathed into Adam’s nostrils “the breath of life” (2:7). God thus breathed his own image into the first human being. Humankind’s moral obligations in the remainder of the Bible rest on this breathing act of God.

The OT authors often employ ruakh simply to denote air in motion or breath from a person’s mouth. However, special instances of the use of ruakh include references to the very life of a person (Gen. 7:22; Ps. 104:29), an attitude or emotion (Gen. 41:8; Num. 14:24; Ps. 77:3), the negative traits of pride or temper (Ps. 76:12), a generally good disposition (Prov. 11:13; 18:14), the seat of conversion (Ezek. 18:31; 36:26), and determination given by God (2 Chron. 36:22; Hag. 1:14).

The NT authors used the Greek term pneuma to convey the concept of spirit. In the world of the NT, the human spirit was understood as the divine part of human reality as distinct from the material realm. The spirit appears conscious and capable of rejoicing (Luke 1:47). Jesus was described by Luke as growing and becoming “strong in spirit” (1:80). In “spirit” Jesus “knew” what certain teachers of the law were thinking in their hearts (Mark 2:8). Likewise, Jesus “was deeply moved in spirit and troubled” at the sickness of a loved one (John 11:33). At the end of his life, Jesus gave up his spirit (John 19:30).

According to Jesus, the spirit is the place of God’s new covenant work of conversion and worship (John 3:5; 4:24). He declared the human spirit’s dependence on God and ascribed great virtue to those people who were “poor in spirit” (Matt. 5:3).

Human beings who were possessed by an evil spirit were devalued in Mediterranean society. In various places in the Synoptic Gospels and the book of Acts, either Jesus or the disciples were involved in exorcisms of such spirits (Matt. 8:28 33; Mark 1:21–28; 7:24–30; 9:14–29; 5:1–20; 9:17–29; Luke 8:26–33; 9:37–42; Acts 5:16).

The apostle Paul pointed to the spirit as the seat of conversion (Rom. 7:6; 1 Cor. 5:5). He described believers as facing a struggle between flesh and spirit in regard to living a sanctified life (Rom. 8:2–17; Gal. 5:16–17). A contradiction seems apparent in Pauline thinking as he appears to embrace Greek dualistic understanding of body (flesh) and spirit while likewise commanding that “spirit, soul and body be kept blameless” (1 Thess. 5:23). However, the Christian struggle between flesh and Spirit (the Holy Spirit) centers around the believer’s body being dead because of sin but the spirit being alive because of the crucified and resurrected Christ (Rom. 8:10). Believers therefore are encouraged to lead a holistic life, lived in the Spirit.

Water is mentioned extensively in the Bible due to its prevalence in creation and its association with life and purity. The cosmic waters of Gen. 1 are held back by the sky (Gen. 1:6 7; cf. Pss. 104:6, 13; 148:4). God is enthroned on these waters in his cosmic temple (Pss. 29:10; 104:3, 13; cf. Gen. 1:2; Ps. 78:69; Isa. 66:1). These same waters were released in the time of Noah (Gen. 7:10–12; Ps. 104:7–9).

Water is also an agent of life and fertility and is therefore associated with the presence of God. Both God himself and his temple are described as the source of life-giving water (Jer. 2:13; 17:13; Joel 3:18; cf. Isa. 12:2–3). Ezekiel envisions this water flowing from beneath the temple and streaming down into the Dead Sea, where it brings life and fecundity (Ezek. 47:1–12; cf. Zech. 14:8). The book of Revelation, employing the same image, describes “the river of the water of life, as clear as crystal, flowing from the throne of God and of the Lamb” (22:1). This imagery is also illustrated in archaeological remains associated with temples. Cisterns are attested beneath the Dome of the Rock (presumably the location of the Jerusalem temple) and beneath the Judahite temple at Arad. Other temples, such as the Israelite high place at Tel Dan, are located close to freshwater springs. The Gihon spring in the City of David may also be associated with the Jerusalem temple (Ps. 46:4; cf. Gen. 2:13).

This OT imagery forms the background for Jesus’ teaching regarding eternal life in the writings of the apostle John. Jesus claims to be the source of living water, and he offers it freely to everyone who thirsts (John 4:10–15; 7:37; Rev. 21:6; 22:17; cf. Rev. 7:17). This water, which produces “a spring of water welling up to eternal life” (John 4:14), is the work of the Holy Spirit in the believer (John 7:38–39).

Water is also described in the Bible as an agent of cleansing. It is extensively employed in purification rituals in the OT. In the NT, the ritual of water baptism signifies the purity and new life of the believer (Matt. 3:11, 16; Mark 1:8–10; Luke 3:16; John 1:26, 31–33; 3:23; Acts 1:5; 8:36–39; 10:47; 11:16; 1 Pet. 3:20–21; cf. Eph. 5:26; Heb. 10:22).

Finally, the NT also reveals Jesus as the Lord of water. He walks on water (Matt. 14:28–29; John 6:19), turns water into wine (John 2:7–9; 4:46), and controls water creatures (Matt. 17:27; John 21:6). Most important, Jesus commands “the winds and the water, and they obey him” (Luke 8:25; cf. Ps. 29:3).

The English term “witness” occurs in both Testaments numerous times, with a wide range of meanings. One common meaning relates to someone who gives legal testimony and to the legitimacy of that testimony (Num. 35:30; Deut. 17:6; 19:15 16, 18; Prov. 12:17; Isa. 8:16, 20). Throughout the NT the term occurs primarily in the context of someone bearing witness—especially God—or testifying to something (Rom. 1:9; 2 Cor. 1:23; Phil. 1:8; 1 Thess. 2:5, 10), though it also has a forensic dimension in regard to one who establishes legal testimony (e.g., Acts 6:13; 7:58; 2 Cor. 13:1; 1 Tim. 5:19; Heb. 10:28).

Central to the concept of witness is the truthfulness of the witness. This was a vital component of the OT concept of witness. Thus, in legal proceedings a lone witness was insufficient to establish testimony against anyone (Deut. 17:6). This principle carries over into the NT (cf. Matt. 18:16; 2 Cor. 13:1). Such truthfulness was so significant that the ninth commandment expressly forbids bearing false witness (Exod. 20:16; Deut. 5:20; cf. Prov. 19:5, 9).

Truth-telling was not something that the people of Israel were called to merely among themselves. They were to be God’s witnesses to the nations (Isa. 43:10; 44:8). As witnesses of God’s existence and holiness, they were called to be separate from the nations (Exod. 19:6) and to be a light to them (Isa. 49:6). Tragically, Israel failed in this responsibility and was deemed “blind” (Isa. 42:19).

The NT continues the concept that the people of God are to be God’s witnesses. John the Baptist is commissioned “to testify concerning that light” (John 1:7). It is in this context that Jesus later declares himself to be “the light of the world” (John 8:12; 9:5). Jesus himself is the exemplar of a “faithful witness” (Rev. 1:5). And his followers, whom he has designated as “the light of the world” (Matt. 5:14), are then called to bear witness to the ends of the earth (Acts 1:8).

“Witness” is also employed in terms of a legal testimony regarding what one has seen. That the disciples were intent on establishing such legal testimony is evident in their stipulation that the person to replace Judas Iscariot be someone from among those who had been with Jesus from the beginning of his ministry to his ascension, so that “one of these must become a witness with us of his resurrection” (Acts 1:22). This forensic aspect of witness appears in the close of the Gospel of John: “This is the disciple who testifies to these things and who wrote them down. We know that his testimony is true” (21:24). Paul demonstrates this forensic concern for witnesses when he references Peter, the Twelve, some five hundred others, and himself as among those who have witnessed the resurrection (1 Cor. 15:3–8).

Throughout Revelation there resides a direct link between Christians bearing witness and suffering, and perhaps dying, as a consequence of this witness. This is evident in the mention of Antipas, who was martyred, and is then designated as “my faithful witness” (Rev. 2:13). Also, the two unnamed witnesses in 11:1–12, who explicitly function as witnesses, are the subject of attack and are eventually murdered. Their murder occurs only after they have finished “their testimony” (11:7).

It is this association of persecution and martyrdom that likely leads to the second-century employment of “martyr” as a designation for those who bear witness to Christ to the point of death.

“Word” is used in the Bible to refer to the speech of God in oral, written, or incarnate form. In each of these uses, God desires to make himself known to his people. The communication of God is always personal and relational, whether he speaks to call things into existence (Gen. 1) or to address an individual directly (Gen. 2:16 17; Exod. 3:14). The prophets and the apostles received the word of God (Deut. 18:14–22; John 16:13), some of which was proclaimed but not recorded. The greatest revelation in this regard is the person of Jesus Christ, who is called the “Word” of God (John 1:1, 14).

The psalmist declared God’s word to be an eternal object of hope and trust that gives light and direction (Ps. 119), and Jesus declared the word to be truth (John 17:17). The word is particularized and intimately connected with God himself by means of the key phrases “your word,” “the word of God,” “the word of the Lord,” “word about Christ,” and “the word of Christ” (Rom. 10:17; Col. 3:16). Our understanding of the word is informed by a variety of terms and contexts in the canon of Scripture, a collection of which is found in Ps. 119.

The theme of the word in Ps. 119 is continued and clarified in the NT, accentuating the intimate connection between the word of God and God himself. The “Word” of God is the eternal Lord Jesus Christ (John 1:1; 1 John 1:1–4), who took on flesh and blood so that we might see the glory of the eternal God. The sovereign glory of Christ as the Word of God is depicted in the vision of John in Rev. 19:13. As the Word of God, Jesus Christ ultimately gives us our lives (John 1:4; 6:33; 10:10), sustains our lives (John 5:24; 6:51, 54; 8:51), and ultimately renders a just judgment regarding our lives (John 5:30; 8:16, 26; 9:39; cf. Matt. 25:31–33; Heb. 4:12).
