With the who-knows-when-book in the back of my mind, I read books and articles with an eye toward finding quotes that explain what I want to say better than I can say it. Here is one example; it is C.S. Lewis describing the new life Christians have in Christ:
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.
(From Mere Christianity, p. 64)
