Bridge-players tell me that there must be some money on the game 'or else people won't take it seriously'. Apparently it's like that. Your bid - for God or no God, for a good God or the Cosmic Sadist, for eternal life or nonentity - will not be serious if nothing much is staked on it. And you will never discover how serious it was until the stakes are raised horribly high, until you find that you are playing not for counters or for sixpences but for every penny you have in the world.

He's not safe, but he's good (referring to Aslan, the Lion, in The Lion, the Witch and the Wardrobe)

What seem our worst prayers may really be, in God's eyes, our best. Those, I mean, which are least supported by devotional feeling. For these may come from a deeper level than feeling. God sometimes seems to speak to us most intimately when he catches us, as it were, off our guard.

[S]omething inside us, the feeling of resentment, the feeling that wants to get one's own back, must be simply killed. I do not mean that anyone can decide this moment that he will never feel it anymore. That is not how things happen. I mean that every time it bobs its head up, day after day, year after year, all our lives long, we must hit it on the head. It is hard work, but the attempt is not impossible.

[M]an has been accustomed, ever since he was a boy, to having a dozen incompatible philosophies dancing about together inside his head. He doesn't think of doctrines as primarily "true" or "false," but as "academic" or "practical," "outworn" or "contemporary," "conventional" or "ruthless." Jargon, not argument, is your best ally in keeping him from the Church. Don't waste time trying to make him think that materialism is true! Make him think it is strong or stark or courageous—that it is the philosophy of the future. That's the sort of thing he cares about.

First be sure that you know exactly what you want to say. Then be sure you have said exactly that.

I wish they would remember that the charge to Peter was "Feed my sheep", not "Try experiments on my rats", or even "Teach my performing dogs new tricks".
