Who am I? What is my 'self'? The answer is that I am a Jekyll and Hyde, a mixed-up kid, having both dignity, because I was created and have been re-created in the image of God, and depravity, because I still have a fallen and rebellious nature. I am both noble and ignoble, beautiful and ugly, good and bad, upright and twisted, image and child of God, and yet sometimes yielding obsequious homage to the devil from whose clutches Christ has rescued me. My true self is what I am by creation, which Christ came to redeem, and by calling. My false self is what I am by the fall, which Christ came to destroy.
-From "The Cross of Christ" (John R. W. Stott)
