Hell? What's That?

Noone really talks about Hell. It's almost like we're hoping it doesn't exist. In a way it's almost ridiculous... you could go up to any Christian I know asking about Heaven, and they'd babble on for hours about how freaking amazing it is and all the wonderful things attached. But if you go up the same person a week later and question them about Hell, you'll get a pretty sketchy answer: a vague description and assurance that you don't want to go there. But... why? According to unbiased polls about Christian faith and beliefs, we can't even agree on whether or not Hell is eternal. Is that why nobody ever talks about it? Are we really that unsure? And if we don't even know how long we're supposed to be there, if we only know half of our faith, how can we expect to bring non-believers to our God? Maybe that's why it's so hard to save people these days. I mean, there are countless pamphlets talking about God and Heaven and how you'll go to Hell if you don't believe in them... but it never lists "What's so horrible about Hell" or "How do you know it exists" under Frequently Asked Questions. To some people, that sounds kind of hypocritical.
Now, don't get me wrong, I do believe in Heaven and Hell and all that. I have for my whole life. I'm just saying that, as Christians, we should take a step back and ask ourselves; why do we believe in Hell? Maybe then we wont seem so crazy to non-believers.
