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

15 Brethren, I speak after the manner of men; Though it be but a man's covenant, yet if it be confirmed, no man disannuls, or adds thereto. 16 Now to Abraham and his descendant were the promises made. He says not, And to descendants, as of many; but as of one, And to your descendant, who is Christ. 17 And this I say, that the covenant, that was confirmed before by God in Christ, the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of no effect. 18 For if the inheritance is of the law, it is no more of promise: but God gave it to Abraham by promise.
