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 longa s you are looking down, you cannot see something that is above you.
