Have you ever wanted to be free from all the posing and posturing you catch yourself doing with other people (and if you can't admit the truth of that, you have a whole other problem)? To get rid of this false self, C.S. Lewis argues that contact with God is necessary:
We must not think Pride is something God forbids because He is offended at it, or that Humility is something He demands as due to His own dignity - as if God Himself was proud. He is not in the least worried about His dignity.
The point is, He wants you to know Him: wants to give you Himself. And He and you are two things of such a kind that if you really get into any kind of touch with Him you will, in fact, be humble - delightedly humble, feeling the infinite relief of having for once got rid of all the silly nonsense about your own dignity which has made you restless and unhappy all your life.
He is trying to make you humble in order to make this moment possible: trying to take off a lot of silly, ugly, fancy-dress in which we have all got ourselves up and are strutting about like the little idiots we are. I wish I had got a bit further with humility myself: if I had, I could probably tell you more about the relief, the comfort, of taking the fancy-dress off - getting rid of the false self, with all its 'Look at me' and 'Aren't I a good boy?' and all its posing and posturing.
To get even near it, even for a moment, is like a drink of cold water to a man in a desert.
