Galatians 2:16-20

yet knowing that a man is not justified by the works of the law but through faith in Jesus Christ, even we believed on Christ Jesus, that we might be justified by faith in Christ, and not by the works of the law: because by the works of the law shall no flesh be justified. But if, while we sought to be justified in Christ, we ourselves also were found sinners, is Christ a minister of sin? God forbid. For if I build up again those things which I destroyed, I prove myself a transgressor. For I through the law died unto the law, that I might live unto God. I have been crucified with Christ; and it is no longer I that live, but Christ liveth in me: and that life which I now live in the flesh I live in faith, the faith which is in the Son of God, who loved me, and gave himself up for me.
