17Now 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.
18For if the inheritance is of the law, it is no more of promise: but God hath granted it to Abraham by promise.
19What 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.
20Now a mediator is not [a mediator] of one; but God is one.
21Is 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.
22But the scriptures shut up all things under sin, that the promise by faith in Jesus Christ might be given to them that believe.
23But before faith came, we were kept in ward under the law, shut up unto the faith which should afterwards be revealed.
