It may not say specifically "convince people to believe in god because of hell", but Christians *are* supposed to witness, and the hell card is part of their best arsenal for scaring people into believing.
Yes, this is what I find most abhorrent about the way some Christians witness, but what many of them don't realize is that this belief is actually more ammunition
against god than it is for, as I've known quite a few people, myself included, that turned away from Christianity because of the hideousness in which some portray God-- this fatherly being who is supposedly OF love and yet is capable of such extreme and unforgiving cruelty. This can be likened to the prophet Mohamed using fear of the sword as a means to convert dissidents to Islam. Both methods are equally disgusting and primitive, so we're in agreement on that.
May I ask how/why you believe in god, when you seem to have your head on straight about some of the things that are wrong with religion?
My belief is not that we have some personal deity sheltering and tending to our spiritual well-beings, just to be clear. My spirituality revolves around this certainty that we all need something to believe in-- yes, even atheists. We're all struggling to understand and, since we're all different, we all interpret what we feel our hearts and minds are trying to tell us in many different ways.
My beliefs are difficult to explain because they're constantly "evolving", as I like to consider it. This is why I can't so easily dismiss other people's beliefs, because we're all reaching for the same thing, though we take our separate paths to reach it.
Once more, it's been a pleasure. Hopefully we'll disagree again some time.
