If I had undeniable proof of the existence of Yahweh, aka Jehovah, aka Adonai, aka El Shaddai, aka Yahweh Elohim, the father of Jesus and the ancient leader of the Semitic peoples, I still would not worship the bastard. If an angel appeared to me and removed my appendectomy scar so I could never deny the reality of divine power, I still would not be a Christian. My primary reason for not being a Christian has nothing to do with my lack of belief in their god. My primary reason is that the Bible is a disgusting book describing the behavior of a god without the morality of the average high school student.
That God does what he wants, when he wants, without even an attempt at self-justification, and all for what reason? According to Paul, all for his own greater glory. For his own glory he condemns billions to eternal torment, drowns millions of innocent beasts and thousands of children, orders the slaughter of entire cities down to the last man, woman, and child, creates a race that he knows is flawed and will hurt itself, refuses to deal with any other god on a friendly basis, rains doom on those who dare to try to be as knowledgable as he is, and so on.
