What would have to occur or to have occurred to constitute for you a disproof of the love of, or the existence of, God?

I am open to [the notion of theistic revelation], but not enthusiastic about potential revelation from God. On the positive side, for example, I am very much impressed with physicist Gerald Schroeder's comments on Genesis 1. That this biblical account might be scientifically accurate raises the possibility that it is revelation.

The evidence for the resurrection is better than for claimed miracles in any other religion. It's outstandingly different in quality and quantity.

The Koran calls for belief and consequent obedience. It is, surely, calculated to inspire fear, indeed abject terror, rather than love.

Someone tells us that God loves us as a father loves his children. We are reassured. But then something awful happens. Some qualification is made.... We are reassured again. But then perhaps we ask: what is this assurance of God's (appropriately qualified) love worth, what is this apparent guarantee really a guarantee against? Just what would have to happen not merely (morally and wrongly) to tempt but also (logically and rightly) to entitle us to say "God does not love us" or even "God does not exist"?

I'm thinking of a God very different from the God of the Christian and far and away from the God of Islam, because both are depicted as omnipotent Oriental despots, cosmic Saddam Husseins.
