C.s. Lewis said this quote

You would like to know how I behave when I am experiencing pain, not writing books about it. You need not guess, for I will tell you; I am a great coward... If I knew any way of escape I would crawl through sewers to find it. But what is the good of telling you about my feelings? You know them already; they are the same as yours. I am not arguing that pain is not painful. Pain hurts. That is what the word means. I am only trying to show that the old Christian doctrine of being made 'perfect through suffering' is not incredible. To prove it palatable is beyond my design.
