Galatians 2:19-20

19But God's Law showed me that I could never obey all its rules. So I became like a dead person, free from the authority of those rules. That means that I can now live to please God.

20Christ died on the cross on my behalf. It is like I died there with him. So I do not live my own life any more. Instead, Christ lives in me. The life that I live now in my body, I live because I trust what he has done for me. He has loved me so much that he died on my behalf.
