Galatians 3:15-22

Brethren, I speak after the manner of men: Though it be but a man’s covenant, yet when it hath been confirmed, no one maketh it void, or addeth thereto. Now to Abraham were the promises spoken, and to his seed. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ. Now this I say: A covenant confirmed beforehand by God, the law, which came four hundred and thirty years after, doth not disannul, so as to make the promise of none effect. For if the inheritance is of the law, it is no more of promise: but God hath granted it to Abraham by promise. What then is the law? It was added because of transgressions, till the seed should come to whom the promise hath been made; and it was ordained through angels by the hand of a mediator. Now a mediator is not a mediator of one; but God is one. Is the law then against the promises of God? God forbid: for if there had been a law given which could make alive, verily righteousness would have been of the law. But the scripture shut up all things under sin, that the promise by faith in Jesus Christ might be given to them that believe.
