19 Why, then, was the law given at all? It was added because of transgressions until the Seed to whom the promise referred had come. The law was given through angels and entrusted to a mediator.
20 A mediator, however, implies more than one party; but God is one.
21 Is the law, therefore, opposed to the promises of God? Absolutely not! For if a law had been given that could impart life, then righteousness would certainly have come by the law.
22 But Scripture has locked up everything under the control of sin, so that what was promised, being given through faith in Jesus Christ, might be given to those who believe.

Children of God

23 Before the coming of this faith,a we were held in custody under the law, locked up until the faith that was to come would be revealed.
24 So the law was our guardian until Christ came that we might be justified by faith.
25 Now that this faith has come, we are no longer under a guardian.
