That's what Raymond Tallis says, and I can understand that view. But when he says he's not interested in a God he can't make sense of that's an ethical choice on his part. It doesn't mean it holds for everyone or is the objective truth. Other people may be comfortable with the idea that God is beyond comprehension.

And I don't think the scenario is all that unrealistic. Suppose a loved one was killed in a car accident last week and God said he would make it not happen. Not merely that you would forget about it but that it would not happen at all and life will be at it is without the accident happening. Is the damage still done, even if, more than simply not remembering it, God actually changed reality so it never happened at all?
