Which biblical verses support covenant theology?

Covenant theology is a framework for understanding the overarching narrative of the Bible, emphasizing the role of covenants as the means by which God relates to humanity. This theological perspective posits that God has established a series of covenants throughout history, each advancing His redemptive plan. To support covenant theology, we can look at several key biblical passages that highlight the concept of covenants and their significance in God's relationship with humanity.

Covenant theology often begins with the Covenant of Works, which is seen in the relationship between God and Adam in the Garden of Eden. In Genesis 2:16-17, God commands Adam, saying, "You are free to eat from any tree in the garden; but you must not eat from the tree of the knowledge of good and evil, for when you eat from it you will certainly die." This covenant implies a promise of life for obedience and death for disobedience. Although the term "covenant" is not explicitly used here, Hosea 6:7 refers to Adam's transgression, indicating a covenantal framework: "But like Adam, they have transgressed the covenant; there they have dealt treacherously against Me" (NASB).

Following the fall, God initiates the Covenant of Grace, which is progressively revealed throughout Scripture. This covenant begins with God's promise to Adam and Eve in Genesis 3:15, often called the protoevangelium, or the first gospel. God declares, "And I will put enmity between you and the woman, and between your offspring and hers; he will crush your head, and you will strike his heel." This verse is seen as the first hint of God's redemptive plan through the seed of the woman, ultimately fulfilled in Jesus Christ.

The Noahic Covenant in Genesis 9 further develops the idea of God's gracious dealings with humanity. After the flood, God establishes a covenant with Noah and his descendants, promising never to destroy the earth with a flood again. Genesis 9:11 states, "I establish my covenant with you: Never again will all life be destroyed by the waters of a flood; never again will there be a flood to destroy the earth." This covenant is marked by the sign of the rainbow, serving as a reminder of God's mercy and faithfulness.

The Abrahamic Covenant is another pivotal moment in the unfolding of the Covenant of Grace. In Genesis 12:1-3, God calls Abram and makes several promises: "I will make you into a great nation, and I will bless you; I will make your name great, and you will be a blessing. I will bless those who bless you, and whoever curses you I will curse; and all peoples on earth will be blessed through you." This covenant is further confirmed and expanded in Genesis 15 and 17, where God promises Abraham numerous descendants and the land of Canaan, and institutes circumcision as the covenant sign. The Abrahamic Covenant is foundational to understanding God's plan to bless all nations through Abraham's offspring, ultimately fulfilled in Christ (Galatians 3:16).

The Mosaic Covenant at Mount Sinai is another critical component of covenant theology. In Exodus 19:5-6, God tells the Israelites, "Now if you obey me fully and keep my covenant, then out of all nations you will be my treasured possession. Although the whole earth is mine, you will be for me a kingdom of priests and a holy nation." This covenant, given through Moses, includes the giving of the Law, which serves to guide Israel in their relationship with God and set them apart as His people. The Mosaic Covenant also points to the need for a greater solution to the problem of sin, as the Law reveals humanity's inability to achieve righteousness on their own (Romans 3:20).

The Davidic Covenant is another significant covenant in the biblical narrative. In 2 Samuel 7:12-16, God promises David that his descendants will rule forever: "When your days are over and you rest with your ancestors, I will raise up your offspring to succeed you, your own flesh and blood, and I will establish his kingdom. He is the one who will build a house for my Name, and I will establish the throne of his kingdom forever." This covenant establishes the hope of a Messianic King, a descendant of David who will reign eternally, fulfilled in Jesus Christ (Luke 1:32-33).

The New Covenant, prophesied in the Old Testament and fulfilled in the New Testament, is the culmination of the Covenant of Grace. Jeremiah 31:31-34 provides a profound description of this covenant: "'The days are coming,' declares the Lord, 'when I will make a new covenant with the people of Israel and with the people of Judah. It will not be like the covenant I made with their ancestors when I took them by the hand to lead them out of Egypt, because they broke my covenant, though I was a husband to them,' declares the Lord. 'This is the covenant I will make with the people of Israel after that time,' declares the Lord. 'I will put my law in their minds and write it on their hearts. I will be their God, and they will be my people. No longer will they teach their neighbor, or say to one another, "Know the Lord," because they will all know me, from the least of them to the greatest,' declares the Lord. 'For I will forgive their wickedness and will remember their sins no more.'"

This New Covenant is inaugurated by Jesus Christ, as seen in Luke 22:20, where Jesus, at the Last Supper, says, "This cup is the new covenant in my blood, which is poured out for you." The New Covenant brings the ultimate fulfillment of God's redemptive plan, providing forgiveness of sins and the indwelling of the Holy Spirit, enabling believers to live in obedience to God.

The Epistle to the Hebrews extensively discusses the superiority of the New Covenant over the old, particularly in Hebrews 8:6-13. Verse 6 states, "But in fact the ministry Jesus has received is as superior to theirs as the covenant of which he is mediator is superior to the old one, since the new covenant is established on better promises." This passage goes on to quote Jeremiah 31, emphasizing the fulfillment of the New Covenant in Christ.

In summary, covenant theology is deeply rooted in Scripture, with numerous verses supporting the concept of covenants as central to God's relationship with humanity. From the Covenant of Works with Adam to the New Covenant in Christ, these covenants reveal God's unfolding plan of redemption, culminating in the person and work of Jesus Christ. This framework helps us understand the unity and coherence of the biblical narrative, highlighting God's faithfulness and grace throughout history.
