Christians concoct many different scenarios about what they'll do in heaven for all eternity. None of them make good sense. Will they eternally play golf? Baseball? How about hockey, football, or even rugby? Boxing anyone? What about bear hunting? Hey, guys, how about having everlasting sex with a harem of 70 virgins? Oh, sorry, wrong religion. Regardless, what if YOU were part of a harem of 70 guys for some nymphomaniac in heaven who is just as ugly as YOU are? More seriously, what about being in a prostate position eternally worshiping God? This just seems boring to most Christians, that's all. I can hear some of the saints in heaven now:
Hey, God, can I get up and do something productive? Do you sincerely not want me to do anything now that I'm here? Doing productive activities is self-fulfilling and makes me happy. Let me do something, please, anything. Can I at least get up and stretch, or go catch up with the "few" family and friends of mine that made it here? If nothing else, your wonderfulness, can I go to the bathroom? ;-)
