Galatians 2:18-21

For if I build again those things which I destroyed, I make myself a transgressor. For I through the law died to the law that I might live to God. I have been crucified with Christ; 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 for me. I do not set aside the grace of God; for if righteousness comes through the law, then Christ died in vain.”
