Mere Christianity - C. S. Lewis [64]
You may ask, ‘if we cannot imagine a three-personal Being, what is the good of talking about Him?’ Well, there isn’t any good talking about Him. The thing that matters is being actually drawn into that three-personal life, and that may begin any time—tonight, if you like.
What I mean is this. An ordinary simple Christian kneels down to say his prayers. He is trying to get into touch with God. But if he is a Christian he knows that what is prompting him to pray is also God: God, so to speak, inside him. But he also knows that all his real knowledge of God comes through Christ, the Man who was God—that Christ is standing beside him, helping him to pray, praying for him. You see what is happening. God is the thing to which he is praying—the goal he is trying to reach. God is also the thing inside him which is pushing him on—the motive power. God is also the road or bridge along which he is being pushed to that goal. So that the whole threefold life of the three-personal Being is actually going on in that ordinary little bedroom where an ordinary man is saying his prayers. The man is being caught up into the higher kinds of life—what I called Zoe or spiritual life: he is being pulled into God, by God, while still remaining himself.
And that is how Theology started. People already knew about God in a vague way. Then came a man who claimed to be God; and yet He was not the sort of man you could dismiss as a lunatic. He made them believe Him. They met Him again after they had seen Him killed. And then, after they had been formed into a little society or community, they found God somehow inside them as well: directing them, making them able to do things they could not do before. And when they worked it all out they found they had arrived at the Christian definition of the three-personal God.
This definition is not something we have made up; Theology is, in a sense, an experimental science. It is simple religions that are the made-up ones. When I say it is an experimental science ‘in a sense’, I mean that it is like the other experimental sciences in some ways, but not in all. If you are a geologist studying rocks, you have to go and find the rocks. They will not come to you, and if you go to them they cannot run away. The initiative lies all on your side. They cannot either help or hinder. But suppose you are a zoologist and want to take photos of wild animals in their native haunts. That is a bit different from studying rocks. The wild animals will not come to you: but they can run away from you. Unless you keep very quiet, they will. There is beginning to be a tiny little trace of initiative on their side.
Now a stage higher; suppose you want to get to know a human person. If he is determined not to let you, you will not get to know him. You have to win his confidence. In this case the initiative is equally divided—it takes two to make a friendship.
When you come to knowing God, the initiative lies on His side. If He does not show Himself, nothing you can do will enable you to find Him. And, in fact, He shows much more of Himself to some people than to others—not because He has favourites, but because it is impossible for Him to show Himself to a man whose whole mind and character are in the wrong condition. Just as sunlight, though it has no favourites, cannot be reflected in a dusty mirror as clearly as in a clean one.
You can put this another way by saying that while in other sciences the instruments you use are things external to yourself (things like microscopes and telescopes), the instrument through which you see God is your whole self. And if a man’s self is not kept clean and bright, his glimpse of God will be blurred—like the Moon seen through a dirty telescope. That is why horrible nations have horrible religions: they have been looking at God through a dirty
