Galatians 2:16-21

16Knowing 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 may 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. 17But if, while we seek to be justified by Christ, we ourselves also are found sinners, is therefore Christ the minister of sin? By no means. 18For if I build again the things which I destroyed, I make myself a transgressor. 19For I through the law am dead to the law, that I may live to God. 20I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. 21I do not set aside the grace of God: for if righteousness is gained by the law, then Christ hath died in vain.
