If it turns out that Yahweh exists all of us atheists and agnostics are going to hell for eternity right? Wrong, and here is why: According to every Christian that I have ever asked Yahweh is a just god. However punishing people for not holding a belief is unjust (especially punishing them for eternity, but really any punishment at all would be unjust). Therefore even if Yahweh turns out to exist atheists and agnostics have nothing to fear. This argument applies to any god that is supposed to be just. There are some things which we would hold people accountable for not believing. For example if a parent let a child starve because they believed that the child could live without food we would hold them accountable for that, however belief in a god in general, and Yahweh or any other specific god in particular, is not on par with that sort of belief, and therefore not grounds for punishment.
