Question
What are the covenants in the Bible? (the major agreements God makes with His people)
Analysis
A single unfolding story
The covenants build on one another rather than replacing each other at random. The Abrahamic promise (blessing to all nations, Genesis 12:3) sets the trajectory; the Mosaic covenant shapes Israel as a nation to carry it; the Davidic covenant narrows the promise to a coming king from David's line (2 Samuel 7:16); and the new covenant brings the forgiveness and heart-change the earlier ones pointed toward. The New Testament presents Jesus as the one in whom the promises converge, the offspring of Abraham (Galatians 3:16), the son of David (Matthew 1:1), and the mediator of the new covenant (Hebrews 8:6).
The new covenant and the old
Jeremiah foretold a new covenant, not like the one Israel broke, in which God writes His law on hearts and remembers sin no more (Jeremiah 31:31–Jeremiah 31:34). Jesus took the cup at the Last Supper and called it 'the new covenant in my blood' (Luke 22:20; 1 Corinthians 11:25). Hebrews explains that this makes the old, Mosaic arrangement 'obsolete' as a system (Hebrews 8:13) while fulfilling everything it anticipated. How exactly the Mosaic Law now applies to Christians is discussed differently across traditions (covenant theology vs dispensationalism), a seam noted, but all agree the new covenant is established in Christ.
