Galatians 3:15-18 - The Promise To Abraham And His Descendant
15 Brothers, speaking of human terms, though it is only a man's covenant, yet when it has been confirmed, no one makes it void, or adds to it. 16 Now the promises were spoken to Abraham and to his seed. He does not say, "To seeds," as of many, but as of one, "To your seed," which is Christ. 17 Now I say this. A covenant confirmed beforehand by God, the law, which came four hundred thirty years after, does not annul, so as to make the promise of no effect. 18 For if the inheritance is of the law, it is no more of promise; but God has granted it to Abraham by promise.
