In biblical theology, the concept of a covenant is central to understanding the relationship between God and His people. A covenant is a solemn agreement or promise, often accompanied by specific terms and conditions, that establishes a binding relationship. The Bible records several covenants, each with its own set of terms, which reveal God's unfolding plan for humanity.

The Noahic Covenant

The Noahic Covenant, found in Genesis 9:8-17, is established between God and Noah following the flood. The terms of this covenant include God's promise never to destroy the earth with a flood again. The sign of this covenant is the rainbow: "I have set My rainbow in the clouds, and it will be a sign of the covenant between Me and the earth" (Genesis 9:13). This covenant is unconditional, requiring no specific actions from Noah or his descendants.

The Abrahamic Covenant

The Abrahamic Covenant, detailed in Genesis 12, 15, and 17, is a foundational covenant in which God promises Abraham land, descendants, and blessing. The terms include God's commitment to make Abraham a great nation and to bless all the families of the earth through him: "I will make you into a great nation, and I will bless you; I will make your name great, so that you will be a blessing" (Genesis 12:2). The sign of this covenant is circumcision, as stated in Genesis 17:10-11.

The Mosaic Covenant

The Mosaic Covenant, also known as the Sinaitic Covenant, is established between God and the Israelites at Mount Sinai. The terms are outlined in the Torah, particularly in Exodus 19-24. This covenant includes the Ten Commandments and various laws governing religious, moral, and social life. God promises to make Israel His treasured possession if they obey His voice and keep His covenant: "Now if you will indeed obey My voice and keep My covenant, you will be My treasured possession out of all the nations" (Exodus 19:5). This covenant is conditional, requiring Israel's obedience.

The Davidic Covenant

The Davidic Covenant, found in 2 Samuel 7:12-16, is God's promise to David that his lineage will endure forever and that his throne will be established eternally. The terms include God's commitment to raise up David's offspring to succeed him and to establish his kingdom: "Your house and kingdom will endure forever before Me, and your throne will be established forever" (2 Samuel 7:16). This covenant is unconditional, emphasizing God's sovereign choice and promise.

The New Covenant

The New Covenant is prophesied in Jeremiah 31:31-34 and fulfilled in the New Testament through Jesus Christ. The terms of this covenant involve the internalization of God's law and the forgiveness of sins: "I will put My law in their minds and inscribe it on their hearts. And I will be their God, and they will be My people" (Jeremiah 31:33). Jesus, at the Last Supper, identifies His sacrificial death as the establishment of this covenant: "This cup is the new covenant in My blood, which is poured out for you" (Luke 22:20). The New Covenant is characterized by grace and is accessible to all who believe in Christ.

Each covenant in the Bible reveals aspects of God's character and His redemptive plan. The terms of these covenants highlight the responsibilities and blessings associated with being in a relationship with God, ultimately pointing to the fulfillment of His promises through Jesus Christ.
