Galatians 2:15-21 - Justified By Faith In Christ

15 We, who are Jews by birth, and not sinners of the gentiles, 16 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 shall no flesh be justified. 17 But if while we seek to be justified by Christ, we ourselves also are found sinners, is Christ therefore the minister of sin? 18 God forbid. And if I build again the same things which I demolished, I shew myself a transgressor: for I through the law am dead to the law, 19 that I might live unto God. 20 I am crucified with Christ; yet I live, though no longer I, but Christ liveth in me: and the life which I now live in the flesh, I live by faith in the Son of God, who loved me, and gave up himself for me. 21 I do not frustate the grace of God: for if righteousness be by the law, then Christ died in vain.
