17 My point is this: the Law which arose four hundred and thirty years later does not repeal a will previously ratified by God, so as to cancel the Promise.
18 If the Inheritance is due to law, it ceases to be due to promise. Now it was by a promise that God bestowed it on Abraham.
19 Then what about the Law? Well, it was interpolated for the purpose of producing transgressions till such time as the Offspring arrived to whom the Promise was made; also, it was transmitted by means of angels through the agency of an intermediary
20 (an intermediary implies more than one party, but God is one).
21 Then the Law is contrary to God's Promises? Never! Had there been any law which had the power of producing life, righteousness would really have been due to law,
22 but Scripture has consigned all without exception to the custody of sin, in order that the promise due to faith in Jesus Christ might be given to those who have faith.
23 Before this faith came, we were confined by the Law and kept in custody, with the prospect of the faith that was to be revealed;
24 the Law thus held us as wards in discipline, till such time as Christ came, that we might be justified by faith.
