Galatians 2:15-18

We who are Jews by nature, and not sinners of the Gentiles, knowing that a man is not justified by the works of the law but by faith in Jesus Christ, even we have believed in Christ Jesus, that we might be justified by faith in Christ and not by the works of the law; for by the works of the law no flesh shall be justified. “But if, while we seek to be justified by Christ, we ourselves also are found sinners, is Christ therefore a minister of sin? Certainly not! For if I build again those things which I destroyed, I make myself a transgressor.
