The Abrahamic Covenant is really the beginnings of the formal revelation of the covenant of grace, of God's decision to reach into humanity and specifically save people for Himself. It comes in the form of a promise to Abraham. Abraham, who's the son of an idolater, who did not know God. God takes the initiative with him, calls him into a relationship with Himself, and makes just unilaterally some promises to Abraham. He promises that Abraham is going to be a great nation, that he is going to be given a land, a place to live, and that through Him, all of the nations will be blessed.
