Galatians 3:16-18

16Now the promises were spoken 1to Abraham and to his seed. He does not say, “And to seeds,” as one would in referring to many, but rather as in referring to one, “2And to your seed,” that is, Christ. 17What I am saying is this: the Law, which came 3430 years later, does not invalidate a covenant previously ratified by God, so as to nullify the promise. 18For 4if the inheritance is 5based on law, it is no longer 6based on a promise; but 7God has granted it to Abraham by means of a promise.
