Galatians 2:19-21
19For I through the law am dead to the law, that I might live unto God.
20I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.
21I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain.
(KJV)
