The Bible tells you to know yourself, or to be certain. Certainty is always of God. When you love someone you have perceived him as he is, and this makes it possible for you to know him. Until you first perceive him as he is you cannot know him. While you ask questions about him you are clearly implying that you do not know God. Certainty does not require action. When you say you are acting on the basis of knowledge, you are really confusing knowledge with perception. Knowledge provides the strength for creative thinking, but not for right doing. Perception, miracles and doing are closely related. Knowledge is the result of revelation and induces only thought. Even in its most spiritualized form perception involves the body. Knowledge comes from the altar within and is timeless because it is certain. To perceive the truth is not the same as to know it.
