“Christianity tells people to repent and promises them forgiveness. It therefore has nothing (as far as I know) to say to people who do not know they have done anything to repent of and who do not feel that they need any forgiveness. It is after you have realized that there is a real moral law and a power behind that law, and that you have broken that law and put yourself wrong with that power — it is after all this, and not a moment sooner, that Christianity begins to talk. When you know you are sick, you will listen to the doctor. When you have realized that our position is nearly desperate you will begin to understand what the Christians are talking about…
They tell you how the demands of this law, which you and I cannot meet, have been met on our behalf, how God Himself becomes a man to save man from the disapproval of God.
…All I am doing is to ask people to face the facts - to understand the questions which Christianity claims to answer. And they are very terrifying facts. I wish it was possible to say something more agreeable. But I must say what I think true. Of course, I quite agree that the Christian religion is, in the long run, a thing of unspeakable comfort. But it does not begin in comfort; it begins in the dismay I have been describing, and it is no use at all trying to go on to that comfort without first going through that dismay. In religion, as in war and everything else, comfort is the one thing you cannot get by looking for it. If you look for truth, you may find comfort in the end: if you look for comfort you will not get either comfort or truth — only soft soap and wishful thinking to begin with and, in the end, despair.”
