some Christians will say that you are not a "Real" Christian after reading your post. they will say that you can't pick out stuff to believe in and see the rest as a metaphor. they will especially have a problem about the fact that you believe in the big bang. Some Christians will say that you are gonna Burn for that.
Sure, but everyone chooses how they interpret any literature to a certain degree. If I'm reading a science textbook on evolution and I see the classic cartoon with the giraffes and their necks (the shorter ones dying out because they can't reach the trees), do I assume the science textbook is false unless all trees are as tall as giraffes? Do I assume that there's one day between the frames, one century, a million years? Do I assume the text underneath the cartoon is describing this cartoon, or something else entirely? These are all assumptions and interpretations taken as common knowledge in our culture and our society, so we know exactly how to read into them.
The key is I'm not "picking out stuff to believe in" any more than they really are. Unless they are (for instance) wearing clothes made of more than one fabric amongst many other things (Leviticus 19:19., they don't have a leg to stand on in that debate.
so my big problem with religion is that there is SOOO many possibilities. So many Different religions and different ways to understand it. and all this talk about hell and a punishing afterlife just because you didn't believe in something unnatural described in a book, is just rubbing me the wrong way.
The bible's message is one of forgiveness, and it does tell us that no-one will be judged until everyone has been given the chance to see and repent. Unfortunately I don't have time to dig out the corresponding passage now, but will later if you like.
The big bang theory, to my knowledge nobody knows what caused the big bang? Could it be possible that God caused the Big Bang?
I believe God set the universe in motion somehow. Whether he did this directly through the big bang, or through something else entirely, I don't know - and I fully support and encourage science to try to investigate this as much as they can. Just because we don't really know what caused the big bang, I think it would be a disservice to God to just "wheel him in" (as Dawkins puts it) to cover up our lack of knowledge.
BikerEcho quoted above saying many Christians believe your will "burn" for not believing in god or even worst let's say for sinning etc. Doesn't the Christian religion firmly believe in forgiveness? When does this come into play?
Yes, it does believe in forgiveness - from *anything* you could do. The key is you have to accept Jesus as saviour and ask for forgiveness - there's debate on when you can still do that, but some maintain you could do it after you died and still be saved. It's nothing about praying "hard enough", you just need to ask (the murderer on the cross alongside Jesus asked for forgiveness and it was simply given to him then and there.) Heck, some maintain that *everyone* is saved somehow (look up universalism.)
Regardless, going into Christianity because of a "fear" aspect is the wrong way about it - if you believe it's true, then there's nothing to be afraid of (because you can be forgiven easily enough) and if you believe it isn't true, then there's nothing to be afraid of because, well, you don't believe it's true!
