One Covenant of Grace, established at the fall, further established in Abraham, confirmed in Christ.

And this I say, that the covenant, that was confirmed before of God in Christ [diathēkē kekyrōmenē eis Christon], the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of none effect. (Galatians 3:17, KJV)
