The supreme vice

If anyone thinks that Christians regard unchastity as the supreme vice, he is quite wrong. The sins of the flesh are bad, but they are the least bad of all sins. All the worst pleasures are purely spiritual: the pleasure of putting other people in the wrong, of bossing and patronising and spoiling sport, and back-biting, the pleasures of power, of hatred. For there are two things inside me, competing with the human self which I must try to become. They are the Animal self, and the Diabolical self. The Diabolical self is the worse of the two. That is why a cold, self-righteous prig who goes regularly to church may be far nearer to hell than a prostitute. But, of course, it is better to be neither.

Living in the present

Jesus said,] "But now tell me, where do you spend most of your time in your mind, in your imagination: in the present, in the past, or in the future?”

Mack thought for a moment before answering. “I suppose I would have to say that I spend very little time in the present. I spend a big piece in the past, but most of the rest of the time, I am trying to figure out the future.” 

“Not unlike most people. When I dwell with you, I do so in the present—I live in the present. Not the past, although much can be remembered and learned by looking back, but only for a visit, not an extended stay. And for sure, I do not dwell in the future you visualize or imagine. Mack, do you realize that your imagination of the future, which is almost always dictated by fear of some kind, rarely, if ever, pictures me there with you?” 

Again Mack stopped and thought. It was true. He spent a lot of time fretting and worrying about the future, and in his imagination it was usually pretty gloomy and depressing, if not outright horrible. And Jesus was also correct in saying that in Mack’s thoughts of the future, God was always absent. “Why do I do that?” asked Mack. 

“It is your desperate attempt to get some control over something you can’t. It is impossible for you to take power over the future because it isn’t even real, nor will it ever be real. You try to play God, imagining the evil that you fear becoming reality, and then you try to make plans and contingencies to avoid what you fear.”

Remember the signs

But long before she had got anywhere near the edge, the voice behind her said, “Stand still. In a moment I will blow. But, first, remember, remember, remember the signs. Say them to yourself when you wake in the morning and when you lie down at night, and when you wake in the middle of the night. And whatever strange things may happen to you, let nothing turn your mind from following the signs.

And secondly, I give you a warning. Here on the mountain I have spoken to you clearly: I will not often do so down in Narnia. Here on the mountain, the air is clear and your mind is clear; as you drop down into Narnia, the air will thicken. Take great care that it does not confuse your mind.

And the signs which you have learned here will not look at all as you expect them to look, when you meet them there. That is why it is so important to know them by heart and pay no attention to appearances. Remember the signs and believe the signs. Nothing else matters. And now, daughter of Eve, farewell—”
