A technical term for “promise” does not appear in
the OT, but its concept is present throughout Scripture. God unfolds
the history of redemption by employing the idea of promises. The
writers of the NT repeatedly assert that Jesus Christ has fulfilled
God’s promises in the OT (e.g., Luke 24:44–48; 1 Cor.
15:3–8).
Old
Testament
The
promises in the OT are closely related to the history of salvation.
At each stage of redemptive history, God delivered a new message
about redemption, usually in the form of a covenant. Immediately
after the fall of humankind, God first revealed his plan of
salvation: the promise that the seed of the woman would ultimately
crush the head of the serpent (Gen. 3:15). After the flood, God made
a covenant with Noah, promising never again to destroy the earth with
a flood (Gen. 8:21–9:17).
Most
remarkable is the promise that God made to Abraham, Isaac, and Jacob
(Gen. 12:1–3; 13:14–17; 17:4–8; 22:17–18;
26:1–5; 28:13–15). God called Abraham in order to give
him three specific blessings: the land, descendants, and the channel
of blessing among the nations. As a sign of his promise, God made a
covenant of circumcision with Abraham and his descendants (17:10–14).
With Isaac (26:1–5) and Jacob (28:13–15), God repeatedly
reconfirmed the promise made to Abraham. At the time of the exodus
and later the settlement in Canaan, God’s promise to Abraham
was partially fulfilled by multiplying his descendants into millions
and by giving them the promised land.
At
Mount Sinai, God made another covenant with the Israelites. In this
covenant, God promised that they would be his “treasured
possession” among the nations if they would obey him and keep
his covenant (Exod. 19:5). God’s special blessings were
pronounced for them to be “a kingdom of priests and a holy
nation” (19:6). For this purpose, God gave them the Ten
Commandments, which became the religious and ethical standard for his
covenant people (20:1–17). In the book of Deuteronomy,
moreover, God’s promises were made in the form of blessings to
the obedient and of curses to the disobedient (Deut. 28). Later these
became the criteria by which the kings of Israel were judged to
determine whether they had lived an obedient life.
According
to 2 Sam. 7:11–16, God made an eternal covenant with David,
promising the permanence of David’s house, kingdom, and throne.
In this covenant it was also promised that his offspring would build
the house of the Lord. The Davidic covenant was partially fulfilled
at the time of Solomon, who as king built the house of the Lord, the
first temple in Jerusalem (1 Kings 8:15–25). Later, in the
period of the classical prophets, when the hope for the Davidic
throne was endangered, the permanence of the Davidic throne and
kingdom reappeared in the form of messianic prophecy (Jer. 23:5–8;
Ezek. 37:24–28). This promise was ultimately fulfilled by the
coming of Jesus Christ from the line of David (Matt. 1:1–17).
The
history of Israel shows that although the nation repeatedly broke
God’s covenants, he remained faithful to them. According to
Num. 23:19, God’s promises are absolutely trustworthy: “God
is not human, that he should lie, not a human being, that he should
change his mind. Does he speak and then not act? Does he promise and
not fulfill?” The trustworthiness of God’s promises
results from his unchanging character (Ps. 110:4; Mal. 3:6–7).
The almighty God has the power to fulfill his promises (Isa. 55:11).
When Joshua finished conquering the land of Canaan, he confessed that
God was faithful in keeping all his promises to his ancestors (Josh.
21:45; 23:14–15). Joshua himself witnessed that trusting God’s
promises is a life-and-death issue. Those who had not trusted his
promise to give them the land of Canaan perished in the wilderness,
but those who had trusted his promise were allowed to enter it (Num.
14:1–35).
New
Testament
The
central message of the NT is that God’s promises in the OT are
fulfilled with the coming of Jesus Christ. Matthew’s numerous
citation formulas are evidence of this theme. In Luke 4:16–21
Jesus pronounces the fulfillment of Isaiah’s promise (about the
Messiah’s ministry [Isa. 61:1–3]) in his own life. The
book of Acts specifically states that Jesus’ suffering and
resurrection and the coming of the Holy Spirit are the fulfillment of
the OT promises (2:29–31; 13:32–34). Jesus’
identity both as the descendant of David (Acts 13:23) and as the
prophet like Moses (Acts 3:21–26; cf. Deut. 18:15–18) is
also regarded as the fulfillment of the OT.
Paul’s
view of God’s promises is summarized in this statement: “For
no matter how many promises God has made, they are ‘Yes’
in Christ” (2 Cor. 1:20). According to Rom. 1:2–3,
Paul regards the gospel as the message that God “promised
beforehand through his prophets in the Holy Scriptures regarding his
Son.” In Rom. 4 Abraham’s faith is described in terms of
his trust in God’s promises, which leads to his righteousness.
He is presented as our model of faith in God’s promises. The
famous phrase “according to the Scriptures” in 1 Cor.
15:3–4 is, in a sense, understood by Paul as the fulfillment of
God’s promises regarding Christ’s death and resurrection.
In
the book of Hebrews, the concept of promise plays an important role.
In Heb. 6 Abraham is presented as the exemplary man who trusted in
God’s promise. The author exhorts the Hebrew Christians to
follow Abraham’s model of trust in God’s promise
(6:12–20). The author also asserts that Jesus’ new
covenant is superior to the old one because his ministry “is
established on better promises” (8:6). In Heb. 11 the faith of
the great OT saints is acclaimed in terms of their faith in God’s
promises.
In
the NT, God makes new promises based on the work of Christ, including
the final resurrection and the second coming of Christ (John 5:29;
11:25–26; 1 Cor. 15:48–57; 2 Cor. 4:14;
1 Thess. 4:13–18). Furthermore, the message of the gospel
is presented as multiple promises, including eternal life, the
fullness of life in Christ, the forgiveness of sins, the indwelling
of the Holy Spirit, the peace of God, the knowledge of God, and the
joy of God (Matt. 28:18–20; John 3:16; 10:10; 14:16, 27;
16:20–24; 17:25–26; Phil. 4:4–9; 1 John 1:9).
Human
Promises
The
Scriptures contain many cases of people making promises to other
people. For example, Abraham made promises to the king of Sodom and
to Abimelek (Gen. 14:22–24; 21:22–24). The Israelite
spies made a promise to Rahab (Josh. 2:12–21). People also make
promises to God: Jacob, Jephthah, Hannah, and the returning exiles
(Gen. 28:20–21; Judg. 11:29–40; 1 Sam. 1:11–20;
Neh. 10:28–29). Human promises usually are accompanied by the
taking of an oath (Gen. 14:22; 21:24; Deut. 6:13; Josh. 2:12–14)
or the declaration of a curse in case of its breach (Ruth 1:17;
1 Sam. 14:24; 2 Sam. 3:35; 1 Kings 2:23). It is
imperative to keep the promise that one makes to a human being or to
God (Num. 30:1–2; Ps. 50:14). In Mal. 2:14–16, divorce is
regarded as a breaking of the oath between husband and wife. In OT
times, people were afraid of curses falling upon them when they broke
a promise. The Bible warns of the danger of making false promises, as
doing so will bring about sin and judgment (Lev. 19:12; Deut. 23:21;
Zech. 8:17). It is an axiom of the wisdom literature that one should
not make promises rashly or lightly (Prov. 20:25; Eccles. 5:1–7),
and Jesus prohibits the taking of any oath because of the possibility
of its breach (Matt. 5:33–37).
