No live organism can continue for long to exist sanely under conditions of absolute reality;

When I come to my evening prayers and try to reckon up the sins of the day, nine times out of ten the most obvious one is some sin against charity; I have sulked or snapped or sneered or snubbed or stormed. And the excuse that immediately springs to my mind is that the provocation was so sudden and unexpected; I was caught off my guard, I had not time to collect myself. Now that may be an extenuating circumstance as regards those particular acts: they would obviously be worse if they had been deliberate and premeditated. On the other hand, surely what a man does when he is taken off his guard is the best evidence for what sort of a man he is? Surely what pops out before the man has time to put on a disguise is the truth? If there are rats in a cellar you are most likely to see them if you go in very suddenly. But the suddenness does not create the rats: it only prevents them from hiding. In the same way the suddenness of the provocation does not make me an ill-tempered man it only shows me what an ill-tempered man I am. The rats are always there in the cellar, but if you go in shouting and noisily they will have taken cover before you switch on the light. Apparently the rats of resentment and vindictiveness are always there in the cellar of my soul.

What Satan put into the heads of our remote ancestors was the idea that they could "be like gods"—could set up on their own as if they had created themselves—be their own masters—invent some sort of happiness for themselves outside God, apart from God. And out of that hopeless attempt has come nearly all that we call human history—money, poverty, ambition, war, prostitution, classes, empires, slavery—the long terrible story of man trying to find something other than God which will make him happy.

The reason why it can never succeed is this. God made us: invented us as a man invents an engine. A car is made to run on gasoline, and it would not run properly on anything else. Now God designed the human machine to run on Himself. He Himself is the fuel our spirits were designed to burn, or the food our spirits were designed to feed on. There is no other. That is why it is just no good asking God to make us happy in our own way without bothering about religion. God cannot give us a happiness and peace apart from Himself, because it is not there. There is no such thing.
