This "question" is not even an original thought. It's from some fundie tract whose title and author escape me at the moment. But it does highlight a disconcerting theme that is shared between fundies and Muslims. And that is the notion that Heaven is bound by the temporal. In the case of the fundie it's the notion of time. For Muslims it's the notion of sexual relations and the 72 virgins.
