And, perhaps, take notes for a more successful venture of their own. I never thought I would live in times when I felt such despair at the evil on our planet.
you should insert muslim for "islamic terror group"
You know, what if heaven is exactly what you expect, and nothing more? Let's think about that for a moment - the ultimate high destiny for a muslim has been declared to be eternal sex with 70 flawless women. Do they really understand the meaning of the world eternal? The first day would be amazing. The 100th day, even the first year, tours of lust and pleasure beyond description. But there's only 70 of them, and there's only a few hundred positions, and there's only so many times you can do something, no matter how pleasureable, before the pleasure starts to fade. Even the most brutish and lustful among them would start to feel the barest tinges of boredom after, say, 400 years or so, and after that, an ever accelerating desperate attempt to recapture and even exceed the pleasure at the beginning - ever higher expenditures of energy - all for nothing. Then comes the day where he tries to destroy them, and finds that is impossible, because it is what he expects. Then he realizes he is in hell, of his own creation, for eternity.
A religion that relies solely on physical pleasure and not joy to describe heaven has no power to save its adherents from hell.
