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.

The tangible presence of God, experienced as overwhelming power and splendor. The main Hebrew word referring to glory, kabod, has the root meaning “heavy” (1 Sam. 4:18), which in other contexts can mean “intense” (Exod. 9:3; NIV: “terrible”), “wealthy” (i.e., “heavy in possessions” [Gen. 13:2]), and “high reputation” (Gen. 34:19; NIV: “most honored”). When used of God, it refers to his person and his works. God reveals his glory to Israel and to Egypt at the crossing of the sea (Exod. 14:4, 17 19). He carefully reveals his glory to Moses after Israel’s sin with the golden calf in order to assure him that he will not abandon them (33:12–23).

In the NT the glory of God is made real in the person of Jesus Christ (John 1:14; Heb. 1:3). He is, after all, the very presence of God. When he returns on the clouds, he will fully reveal God’s glory (Matt. 24:30; Mark 13:26; Luke 21:27).

Sin enters the biblical story in Gen. 3. Despite God’s commandment to the contrary (2:16 17), Eve ate from the tree of the knowledge of good and evil at the prompting of the serpent. When Adam joined Eve in eating the fruit, their rebellion was complete. They attempted to cover their guilt and shame, but the fig leaves were inadequate. God confronted them and was unimpressed with their attempts to shift the blame. Judgment fell heavily on the serpent, Eve, and Adam; even creation itself was affected (3:17–18).

In the midst of judgment, God made it clear in two specific ways that sin did not have the last word. First, God cryptically promised to put hostility between the offspring of the serpent and that of the woman (Gen. 3:15). Although the serpent would inflict a severe blow upon the offspring of the woman, the offspring of the woman would defeat the serpent. Second, God replaced the inadequate covering of the fig leaves with animal skins (3:21). The implication is that the death of the animal functioned as a substitute for Adam and Eve, covering their sin.

In one sense, the rest of the OT hangs on this question: How will a holy God satisfy his wrath against human sin and restore his relationship with human beings without compromising his justice? The short answer is: through Abraham and his offspring (Gen. 12:1–3), who eventually multiplied into the nation of Israel. After God redeemed them from their slavery in Egypt (Exod. 1–15), he brought them to Sinai to make a covenant with them that was predicated on obedience (19:5–6). A central component of this covenant was the sacrificial system (e.g., Lev. 1–7), which God provided as a means of dealing with sin. In addition to the regular sacrifices made for sin throughout the year, God set apart one day a year to atone for Israel’s sins (Lev. 16). On this Day of Atonement the high priest took the blood of a goat into the holy of holies and sprinkled it on the mercy seat as a sin offering. Afterward he took a second goat and confessed “all the iniquities of the people of Israel, and all their transgressions, all their sins, putting them on the head of the goat, and sending it away into the wilderness. . . . The goat shall bear on itself all their iniquities to a barren region; and the goat shall be set free in the wilderness” (Lev. 16:21–22 NRSV). In order for the holy God to dwell with sinful people, extensive provisions had to be made to enable fellowship.

During the next four hundred years of prophetic silence, the longing for God to finally put away the sins of his people grew. At last, when the conception and birth of Jesus were announced, it was revealed that he would “save his people from their sins” (Matt. 1:21). In the days before the public ministry of Jesus, John the Baptist prepared the way for him by “preaching a baptism of repentance for the forgiveness of sins” (Luke 3:3). Whereas both Adam and Israel were disobedient sons of God, Jesus proved to be the obedient Son by his faithfulness to God in the face of temptation (Matt. 2:13–15; 4:1–11; 26:36–46; Luke 3:23–4:13; Rom. 5:12–21; Phil. 2:8; Heb. 5:8–10). He was also the Suffering Servant who gave his life as a ransom for many (Mark 10:45; cf. Isa. 52:13–53:12). On the cross Jesus experienced the wrath of God that God’s people rightly deserved for their sin. With his justice fully satisfied, God was free to forgive and justify all who are identified with Christ by faith (Rom. 3:21–26). What neither the law nor the blood of bulls and goats could do, Jesus Christ did with his own blood (Rom. 8:3–4; Heb. 9:1–10:18).

After his resurrection and ascension, Jesus’ followers began proclaiming the “good news” (gospel) of what Jesus did and calling to people, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins” (Acts 2:38). As people began to experience God’s forgiveness, they were so transformed that they forgave those who sinned against them (Matt. 6:12; 18:15–20; Col. 3:13). Although believers continue to struggle with sin in this life (Rom. 8:12–13; Gal. 5:16–25), sin is no longer master over them (Rom. 6:1–23). The Holy Spirit empowers them to fight sin as they long for the new heaven and earth, where there will be no sin, no death, and no curse (Rom. 8:12–30; Rev. 21–22).

As even this very brief survey of the biblical story line from Genesis to Revelation shows, sin is a fundamental aspect of the Bible’s plot. Sin generates the conflict that drives the biblical narrative; it is the fundamental “problem” that must be solved in order for God’s purposes in creation to be completed.

Righteousness is an important theme in both Testaments of the Bible. The concept includes faithfulness, justice, uprightness, correctness, loyalty, blamelessness, purity, salvation, and innocence. Because the theme is related to justification, it has important implications for the doctrine of salvation.

Being careful to avoid imposing Western philosophical categories onto OT texts, we may say that the core idea of righteousness is conformity to God’s person and will in moral uprightness, justness, justice, integrity, and faithfulness. Behind the many and varied uses of righteousness language in the OT stands the presupposition that God himself is righteous in the ultimate sense (e.g., Ezra 9:15; Isa. 45:21; Zeph. 3:5). Righteousness is the expression of his holiness in relationship to others (Isa. 5:16), and all other nuances of righteousness in the biblical texts are derived from this.

Related to humans, righteousness is often found as the opposite of wickedness. Righteousness often occurs in evaluative contexts, where it relates to proper conduct with respect to God, the order of the world as he created it, the covenant, or law (e.g., Deut. 6:25). God reigns in righteousness and justice (e.g., Ps. 97:2), and humans should align their conduct with this righteous reign. Righteousness can be expressed as personal integrity with phrases such as “my righteousness” (2 Sam. 22:21, 25; Ps. 7:8) and “their righteousness” (1 Sam. 26:23). Unrighteousness is found in poetic parallel to injustice (e.g., Jer. 22:13); the unjust are parallel with the wicked (Ps. 82:2).

Righteousness language is more rare in the Gospels than one might expect in light of OT and Jewish intertestamental usage. These references fit with the Jewish setting: righteousness is required of God’s people, and unrighteousness is to be avoided. Righteousness is proper conduct with respect to God or Torah (Matt. 21:32) in contrast to wickedness (Matt. 13:49). Righteousness could be conceived as one’s own (e.g., Luke 18:9) and has its reward (Matt. 10:41). While the specific terms related to righteousness are infrequent in the Gospels, the broader concept of conformity to God’s will is widely apparent in calls for repentance, personal moral uprightness, mercy, and concern for the marginalized. The NT Epistles continue these general strands of the concept. Righteousness is related to personal conduct (1 Thess. 2:10; 1 Tim. 6:11; 2 Tim. 2:22; 1 Pet. 2:24) and is contrasted with wickedness (2 Cor. 6:14); it is a matter of doing, not knowing (Rom. 2:13). An example of righteousness in doing is the kindness shown by the prostitute Rahab, who hid the Israelite spies (James 2:25).

The NT does signal some new dimensions related to righteousness. In the Sermon on the Mount (Matt. 5 7), Jesus extends the requirements of righteousness to conformity to his own teaching and directives, a shocking display of authority. In his mission to call sinners rather than the “righteous” (e.g., Mark 2:17), Jesus implicitly questions the righteousness of the “righteous.” In similar manner, personal righteousness in terms of a righteousness of one’s own is negative in the NT (Rom. 10:3; Phil. 3:6; cf. Luke 18:9).

The NT continues the OT theme of righteousness as it relates to God himself. God is righteous (John 17:25; Rom. 3:5; 9:14; Heb. 6:10; cf. Matt. 6:33). His judgments are righteous (Rom. 2:5), and his commands and laws are righteous (Rom. 7:12; 8:4). God is a righteous judge (2 Tim. 4:8). His saving activity is righteous; he does not compromise his own justice in justifying the ungodly (Rom. 3:24–26). The righteousness of God is contrasted with human unrighteousness and wickedness (Rom. 3:5; James 1:20). Since God reigns over creation in righteousness, human conduct should conform to that standard (e.g., Rom. 14:17). Jesus is also noted as righteous (Acts 3:14; 7:52; 22:14; 1 Pet. 3:18; 1 John 2:1, 29). He fulfilled righteousness in the absolute sense of demonstrating complete conformity to the nature and will of God (e.g., 1 Pet. 3:18). He also fulfilled God’s righteousness in the sense of his saving activity toward humans (e.g., 2 Pet. 1:1).

“Salvation” is the broadest term used to refer to God’s actions to solve the plight brought about by humankind’s sinful rebellion and its consequences. It is one of the central themes of the entire Bible, running from Genesis through Revelation.

In many places in the OT, salvation refers to being rescued from physical rather than spiritual trouble. Fearing the possibility of retribution from his brother Esau, Jacob prays, “Save me, I pray, from the hand of my brother Esau” (Gen. 32:11). The actions of Joseph in Egypt saved many from famine (45:5 7; 47:25; 50:20). Frequently in the psalms, individuals pray for salvation from enemies that threaten one’s safety or life (Pss. 17:14; 18:3; 70:1–3; 71:1–4; 91:1–3).

Related to this usage are places where the nation of Israel and/or its king were saved from enemies. The defining example of this is the exodus, whereby God delivered his people from their enslavement to the Egyptians, culminating in the destruction of Pharaoh and his army (Exod. 14:1–23). From that point forward in the history of Israel, God repeatedly saved Israel from its enemies, whether through a judge (e.g., Judg. 2:16; 3:9), a king (2 Kings 14:27), or even a shepherd boy (1 Sam. 17:1–58).

But these examples of national deliverance had a profound spiritual component as well. God did not save his people from physical danger as an end in itself; it was the necessary means for his plan to save them from their sins. The OT recognizes the need for salvation from sin (Pss. 39:8; 51:14; 120:2) but, as the NT makes evident, does not provide a final solution (Heb. 9:1–10:18). One of the clearest places that physical and spiritual salvation come together is Isa. 40–55, where Judah’s exile from the land and prophesied return are seen as the physical manifestation of the much more fundamental spiritual exile that resulted from sin. To address that far greater reality, God announces the day when the Suffering Servant would once and for all take away the sins of his people (Isa. 52:13–53:12).

As in the OT, the NT has places where salvation refers to being rescued from physical difficulty. Paul, for example, speaks of being saved from various physical dangers, including execution (2 Cor. 1:8–10; Phil. 1:19; 2 Tim. 4:17). In the midst of a fierce storm, Jesus’ disciples cry out, “Lord, save us! We’re going to drown!” (Matt. 8:25). But far more prominent are the places in the Gospels and Acts where physical healings are described with the verb sōzō, used to speak of salvation from sin. The healing of the woman with the hemorrhage (Mark 5:25–34), the blind man along the road (Luke 18:35–43), and even the man possessed by a demon (Luke 8:26–39), just to name a few, are described with the verb sōzō. The same verb, however, is also used to refer to Jesus forgiving someone’s sins (Luke 7:36–50) and to his mission to save the lost from their sins (Luke 19:10). Such overlap is a foretaste of the holistic salvation (physical and spiritual) that will be completed in the new heaven and earth (Rev. 21–22). The NT Epistles give extensive descriptions of how the work of Jesus Christ saves his people from their sins.

In the OT, the phrase “son of man” usually refers to humanity in general or to a specific individual. In Ezekiel, for instance, God addresses the prophet himself as “son of man,” possibly indicating his human status compared with God or, alternatively, highlighting his unique status as God’s prophet in contrast with the rest of humanity.

One of the most crucial OT “son of man” texts is Dan. 7 because of its influence on the “Son of Man” in the Gospel tradition. The first half of the chapter records Daniel’s vision (7:1 14), while the second half contains its interpretation (7:15–27). In the vision Daniel sees “one like a son of man, coming with the clouds of heaven” (7:13). This exalted figure contrasts with the first three beasts, which are “like a lion” (7:4), “like a bear” (7:5), and “like a leopard” (7:6). The fourth beast is so gruesome that it defies comparison with any species of the animal kingdom (7:7). Many agree that the beasts likely refer to ancient world empires; however, the referent of “one like a son of man” has given rise to much debate. The figure may refer to earthly Israel, since at this figure’s vindication he is endowed with authority and glory. This is precisely what “the holy people of the Most High” receive in verse 27. In this way, the “one like a son of man” is a symbol for the persecuted, earthly saints. Alternatively, the exalted figure could be a heavenly being such as the archangel Gabriel (9:21) or Michael (10:13; 12:1). Here “one like a son of man” is the heavenly counterpart and leader of suffering Israel and fights a cosmic battle on its behalf.

In the NT the term “Son of Man” occurs mostly in the Gospels and, with the exception of John 12:34 (where the crowd quotes Jesus), is uttered exclusively by Jesus himself. Unlike in Daniel, the epithet occurs in the Gospels with the definite article, likely indicating that the Son of Man was a known figure. In first-century Judaism many Jews believed that the Son of Man would return at the end as savior and judge. The OT provides the most helpful background for understanding the Son of Man in the Gospels.

The Son of Man sayings in the Gospels fall within three categories: earthly, suffering-resurrection, and future-vindication sayings. Starting with the earthly sayings, in Mark 2:10, for example, the Son of Man has “authority on earth to forgive sins,” and in 2:28 he exercises dominion over the Sabbath. Although in Daniel the Son of Man does not receive such authority until his appearance in Yahweh’s presence at his vindication, the Son of Man in the Gospels exercises such authority during his earthly ministry. Jesus also predicts that the Son of Man will suffer, die, and be raised again. In Mark, these suffering-resurrection predictions occur three times (8:31; 9:31; 10:33–34). Echoing Dan. 7, this plight of Jesus recalls the suffering of the holy ones caused by the little horn (v. 21). If the “one like a son of man” represents the holy ones in their vindication, then it is reasonable that he does so in their suffering as well; however, the text of Daniel is silent on this point. Finally, the clearest reference to Dan. 7 occurs in the future-vindication sayings. In Mark 13:26; 14:62 the Son of Man comes with/on the clouds, which points to his vindication over the Sanhedrin, the dominant adversaries of Jesus in Mark. Matthew appears to develop even more than Mark the judicial responsibilities of the Son of Man (Matt. 13:41–43; 25:31–33). Meanwhile, in Luke the church must stay alert and be prepared for the return of the Son of Man (12:39–40; 17:22–37; 21:34–36).

Finally, the Son of Man in Revelation is in the heavenly temple functioning as both judge and caretaker of the seven churches (Rev. 1:12–20) and reaps the saints while “seated on the cloud” (14:14–16).

The way the word “soul” is used in English does not align well with any single Hebrew or Greek word in the Bible. It is widely accepted that the biblical view (both OT and NT) of humanity does not recognize sharp boundaries between body and soul (bipartite anthropology) or between body, soul, and spirit (tripartite). The human being is, according to biblical teaching, a psychosomatic unity.

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.

In the OT, this image is used to convey the concept of a “stumbling block” in a literal (Lev. 19:14) or figurative (Jer. 6:21) sense. In the NT, the image is used as a messianic reference—Christ as a stumbling block (Rom. 9:32 33; 1 Cor. 1:23; 1 Pet. 2:8). This rendition of messianic expectation plays off the Isaianic presentation of God as a stumbling block to his faithless people. The NT Greek words that are translated as “stumbling block” (skandalon) or “to cause to stumble” (skandalizō) have either a christological or a moral application.

The watchman was stationed on the city wall or in a watchtower. He was to identify potential enemies approaching the city and alert the city’s inhabitants by blowing a trumpet (Jer. 6:17; Amos 3:6). It was the duty of some watchmen to inform the king of any suspicious person approaching the city wall (2 Sam. 18:24 27). Just as the watchman warned of potential danger so that people could prepare themselves, so the prophet was to warn of impending judgment on the unrighteous (Ezek. 33:1–11).

“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).
