Galatians 3:15-18 - The Promise To Abraham And His Descendant
15 Brothers, I speak according to man. But no one abolishes a man's covenant when it is established, or makes additions to it. 16 The promises were spoken to Abraham and his offspring. He said not, And to offsprings, as of many, but as of one, And to your offspring, which is Christ. 17 And this I say; that the law which was four hundred and thirty years after, cannot abrogate the covenant previously established by God, to make the promise of no effect. 18 For if the inheritance is by the law, it is no longer by the promise. But God gave it to Abraham by the promise.
