There is a book written by a man who had a near death experience, Didn't You Read My Book? by Dr. Richard E. Eby (available at Amazon). During this experience he asked God many questions. God responded by asking him "Didn't you read my book."
God wants to reveal Himself to us, but do we really want to know Him? Or would we rather know as little as possible so we can go about living our lives as we please.
