“ a Christian is not a man who never goes wrong, but a man who is enabled to repent and pick himself up and begin over again after each stumble ”
 C. S. Lewis, Mere Christianity (1952). copy citation

“As long as the natural life is in your body, it will do a lot towards repairing that body. Cut it, and up to a point it will heal, as a dead body would not. A live body is not one that never gets hurt, but one that can to some extent repair itself. In the same way a Christian is not a man who never goes wrong, but a man who is enabled to repent and pick himself up and begin over again after each stumble—because the Christ-life is inside him, repairing him all the time, enabling him to repeat (in some degree) the kind of voluntary death which Christ Himself carried out.
That is why the Christian is in a different position from other people who are trying to be good. They hope, by being good, to please God if there is one; or—if they think there is not—at least they hope to deserve approval from good men.” source
