Gal 2:17-21

17But if, in our effort to be justified in Christ, we ourselves have been found to be sinners, is Christ then a servant of sin? Certainly not!18But if I build up again the very things that I once tore down, then I demonstrate that I am a transgressor.19For through the law I died to the law, so that I might live to God. I have been crucified with Christ;20and it is no longer I who live, but it is Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me.21I do not nullify the grace of God; for if justification comes through the law, then Christ died for nothing.
