Galatians 3:15-18 - The Promise To Abraham And His Descendant
15 Brothers, I speak like a man speaks: Though it is only a man's covenant, yet when it has been confirmed, no one makes it void, or adds to it. 16 The promises were spoken to Abraham and to his seed. He did not say to seeds, as of many; but as of one, And to your seed, which is Christ. 17 Now this I say: the Law, which came four hundred and thirty years later, does not invalidate a covenant previously ratified by God, so as to nullify the promise. 18 If the inheritance is based on the Law, it is no longer based on a promise. However God granted it to Abraham by means of a promise.
