It's nice to see that you've obviously given this a lot of thought and if you don't mind me saying, you seem pretty passionate too which is cool. What should people be more passionate about than how they view the universe? (Incidentally have we talked before? I think i recognise your name?]
If it's okay may I ask you a question, if right now God proved his existence to you, would you want to go to heaven? In that heaven is being perfectly united with God?
CS Lewis wrote 'There are only two kinds of people in the end: those who say to God, 'Thy will be done,' and those to whom God says, in the end, 'Thy will be done''
God is perfect, not as descriptor, but as a thing. Literally perfect. And heaven is being with God. But for something to be perfect it has to have no faults, and that's not true of any of us, since we chose to be as we are. So he decided that he would take the consequences of our perfection, so that if we ask him, when he'll look on us he'll choose to see perfection instead and in the end, if we let him, he'll make us perfect.
But 'God is love'. Every time you have smiled in your life, every time you've felt love for someone or been loved by someone, that was God. So if you become completely seperate from God, that's how life will be. Without hope, love, humility, patience, kindness, because all of those things ultimately stem from God.
And you don't quite need the bible, it's a shaky point theologically, but it's possible to believe in God, without being told about God it's just a lot harder. And yeah it's an ancient book, but it's an ancient book that's been read by more people in the world than any other book ever. And in the end, he didn't just write a book, he did things with people and left them with experiences that guided them to write the things down that he willed. Even if your atheist, especially if you're atheist, it's almost undeniable that there is no single person in the world that has had a more significant effect on the course of history than Jesus (Except possibly The Buddha there's roughly 500 million Buddhists to 1 billion Christians but I don't know enough eastern/indian history to gauge the overall affect through time). And he was just one guy. To you, one ordinary guy.
You are right Hell is intricately linked to the whole christian faith, but even by reference it's only mentioned a handful of times throughout the whole bible. The vast majority of books don't talk about it/reference it/imply it even once, but you are right, it's there and thing. It's just not the central purpose or even something that's highlighted or particularly valued. People's understanding of hell is far more based on things like Dante's Inferno (which is in itself a lot more focused on mercy and compassion than people think) and Paradise lost.
And I'll be frank with you, hopefully those creationists who talked to you had a think and pray about what they said afterwards. Hell is a thing and a fact but if God sees no joy in it, then they don't have any right to want to see people there either.
Pascal's wager I'll talk about more, because it's something i particularly joy because it suits my world view very well. The point about pascals wager isn't actually about hell as such. It's simply if life is finite, than ultimately there is nothing to be won or lost. It happens, you die, you don't even get to know what happens. The most important thing you care about now will be more than nothing. You could punch someone today and in the blink of an eye no-one will be around to remember it happened. Whereas something eternal will always be infinitely more important than something finite. If you aim for ever and you miss, you won't be around to know and if it is true then you'll have done something that actually has meaning.
But Pascal meant it pretty tongue in cheek, I like it more because I'm a mathematician and like to think that I'm pretty logical and well, if things aren't eternal, then yeah, there aren't really any consequences to our actions. 1/n -> 0 as n ->infinity.
I hope you're okay with what I've said. I don't want to make you irate but I hope you can understand that as much as you can't agree with what I say (unless you do), I can't agree with what you say (unless I do). I feel a little uncomfortable talking like this because 1)I'm not God and so can easily be wrong and 2) The only way I can talk is to talk about what I believe in, but that's something you don't believe in and take objection to, so at best I can only make you feel uncomfortable about my weird mindwashedness
In the end we look at the same thing in a completely different way and we've almost got no common point. Thanks for taking the time to read this, although to you it must just seem like righteous tripe
