Now God, who has made us, knows what we are and that our happiness lies in Him. Yet we will not seek it in Him as long as He leaves us any other resort where it can even be plausibly be looked for. While what we call “our own life” remains agreeable we will not surrender it to Him. What then can God do in our interests but make “our own life” less agreeable to us, and take away the plausible source of false happiness?
--C.S. Lewis, The Problem of Pain
