Lots of good stuff in Galatians:
Galatians 2:16
“Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.”
Galatians 3:19
“Wherefore then
serveth the law? It was added because of transgressions,
till the seed should come to whom the promise was made;
and it was ordained by angels in the hand of a mediator.”

Galatians 3
24Wherefore the law was our schoolmaster
to bring us unto Christ, that we might be justified by faith.
25But after that faith is come, we are no longer under a schoolmaster.
26For ye are all the children of God by faith in Christ Jesus.
27For as many of you as have been baptized into Christ have put on Christ.
