So a Christian fundamentalist asks me, puzzled about the fact that Unitarians and Quakers and similar religions take no position on whether there is a heaven or hell, "why belong to a religion if it doesn't promise you heaven?"
Apparently, many people believe that the only reason to belong to a religion is not because it is a moral framework for behavior, but because you'll get lots of goodies if you belong, and any religion that doesn't promise you goodies for belonging is bogus. If they don't promise you Heaven, why go to church?
Ohhhkay.... I think I can dig where they're coming from. But I'm more practical than them. I don't want something after I die. I want something now. I want a pony! If a religion doesn't promise me a pony, why should I join?
