Vitamin Z has a quote from D.A. Carson that is well worth repeating.
But despite all the mysteries bound up with the nature of God, I perceive, on the basis of Scripture, that he is simultaneously personal and transcendent. He is utterly sovereign over his created order, yet he is nothing less than personal as he deals with me. Sometimes it is more important to worship such a God than to understand him.
