The Christians are right: it is Pride which has been the chief cause of misery in every nation and every family since the world began. Other vices may sometimes bring people together: you may find good fellowship and jokes and friendliness among drunken people or unchaste people. But pride always means enmity — is is enmity. And not only enmity between man and man, but enmity to God.
In God you come up against something which is in every respect immeasurably superior to yourself. Unless you know God as that — and, therefore, know yourself as nothing in comparison — you do not know God at all. As long as you are proud you cannot know God. A proud man is always looking down on things and people: and, of course, as long as you are looking down, you cannot see something that is above you.
~ C.S. Lewis (Mere Christianity)
