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.
19. Why then the law? It was added because of transgressions, till the descendant should come to whom the promise was made; and it was ordained by angels in the hand of a mediator.
20. Now a mediator is not a mediator of one, but God is one.
21. Is the law then against the promises of God? God forbid: for if there had been a law given which could have given life, verily righteousness should have been by the law.
22. But the scripture has consigned all under sin, that the promise by faith in Jesus Christ might be given to them that believe.
23. But before faith came, we were kept under the law, shut up unto the faith which should afterwards be revealed.
24. Therefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.
