Galatians 3:15-18 - The Promise To Abraham And His Descendant

¹⁵ To give a human example, brethren: even though it is only a man's covenant, yet when it has been ratified, no one sets it aside or adds conditions to it. ¹⁶ Now the promises were spoken to Abraham and to his seed. He does not say, "And to seeds," as referring to many, but rather to one, "And to your seed," that is, Christ. ¹⁷ What I mean is this: 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 For if the inheritance is based on the law, it is no longer based on a promise; but God gave it to Abraham by a promise.
