Galatians 2:16-17
2:16 yet we know that no one is justified by the works of the law but by the faithfulness of Jesus Christ. And we have come to believe in Christ Jesus, so that we may be justified by the faithfulness of Christ and not by the works of the law, because by the works of the law no one will be justified.
2:17 But if while seeking to be justified in Christ we ourselves have also been found to be sinners, is Christ then one who encourages sin? Absolutely not!
