[What if you went before God when you died - and discovered that it was Allah? What would you do?]

Since that is not a possibility, I have no answer.

[Oh go on - how about if we pretend that this happened in a dream?]

Funny you should mention this as a dream. I was just thinking (while walking down the hall at work), maybe I should think of this as some crazy nightmare, then I might be able to give you an answer . But low and behold, that didn't help...I'd be praying to Jesus to wake me up from such a horrible thing.
(Wow, for a couple moments, I was thinking the same as an atheist )
