Christ in me - the only power a dead man has to live again and to live right. It's all Christ and none of me. Before Christ, I was dead in trespasses and sins; and without yielding to Christ living through me I have no power to overcome sin and live for God.
"I 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." Galatians 2:20
