In the sixth chapter, “Human Pain,” from The Problem of Pain (1940), C.S. Lewis writes:
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. But what is that to the purpose? When I think of pain—of anxiety that gnaws like fire and loneliness that spreads out like a desert, and the heartbreaking routine of monotonous misery, or again of dull aches that blacken our whole landscape or sudden nauseating pains that knock a man’s heart out at one blow, of pains that seem already intolerable and then are suddenly increased, of infuriating scorpion-stinging pains that startle into maniacal movement a man who seemed half dead with his previous tortures—it “quite o’ercrows my spirit.” 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.
I am progressing along the path of life in my ordinary contentedly fallen and godless condition, absorbed in a merry meeting with my friends for the morrow or a bit of work that tickles my vanity to-day, a holiday or a new book, when suddenly a stab of abdominal pain that threatens serious disease, or a headline in the newspapers that threatens us all with destruction, sends this whole pack of cards tumbling down. At first I am overwhelmed, and all my little happinesses look like broken toys. Then, slowly and reluctantly, bit by bit, I try to bring myself into the frame of mind that I should be in at all times. I remind myself that all these toys were never intended to possess my heart, that my true good is in another world and my only real treasure is Christ. And perhaps, by God’s grace, I succeed, and for a day or two become a creature consciously dependent on God and drawing its strength from the right sources. But the moment the threat is withdrawn, my whole nature leaps back to the toys: I am even anxious, God forgive me, to banish from my mind the only thing that supported me under the threat because it is now associated with the misery of those few days. Thus the terrible necessity of tribulation is only too clear. God has had me for but forty-eight hours and then only by dint of taking everything else away from me. Let Him but sheathe that sword for a moment and I behave like a puppy when the hated bath is over —I shake myself as dry as I can and race off to reacquire my comfortable dirtiness, if not in the nearest manure heap, at least in the nearest flower bed. And that is why tribulations cannot cease until God either sees us remade or sees that our remaking is now hopeless.
