Galatians 2:18-21

For if I rebuild what I have once destroyed, I prove myself to be a transgressor. For through the Law I died to the Law, so that I might live to God. I have been crucified with Christ; and it is no longer I who live, but Christ lives 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 Himself up for me. I do not nullify the grace of God, for if righteousness comes through the Law, then Christ died needlessly.”
