20 Now a mediator is not of one, yet God is one.
21 So then, was the law contrary to the promises of God? Let it not be so! For if a law had been given, which was able to give life, truly justice would be of the law.
22 But Scripture has enclosed everything under sin, so that the promise, by the faith of Jesus Christ, might be given to those who believe.
23 But before the faith arrived, we were preserved by being enclosed under the law, unto that faith which was to be revealed.
24 And so the law was our guardian in Christ, in order that we might be justified by faith.
25 But now that faith has arrived, we are no longer under a guardian.
26 For you are all sons of God, through the faith which is in Christ Jesus.
