Well, I don't have a religion, so I'm not sure that you're going to get very far.
Actually, most atheists don't believe that such a thing as a "soul" exists in the first place.
I'm sorry you find so little joy or happiness in this life. Yes, there are horrible things in the world, but there are also beautiful things that, for most of us, make life worth living. I hope you find some.
Oh, so this is Pascal's Wager. Okay, here's what's wrong with Pascal's Wager:
1. I can't force a belief. If I see no reason to imagine that your God is anything but the invention of the human imagination, I literally, physically CAN'T just up and start believing in him to hedge my bets. Can you manage the sincere belief that you are a duck? How about that the sky is green with neon pink polka dots? Believe that. Or that your mother is a space alien from the planet Quoz. Can you believe that one?
2. There are plenty of religions, not just Christianity. What if the ancient Egyptians were right, and what I really have to worry about is my soul weighing less than a feather so I don't get eaten by a giant crocodile? Or what if I have to die in glorious battle in order to pass into Valhalla, as the Vikings believed?
3. Isnt your God supposed to be omniscient? So wouldn't he know if I was only pretending to believe in case hell was real? Do yo really think your God is stupid enough that I could put one over on him like that?
So-called "near death experiences" are hallucinations of an oxygen-starved brain. They are not evidence of an afterlife.
It's not the case that "one of these religions must be right" -- they could just as easily all be wrong.
"The word of the Lord has never been wrong yet." Really? Wasn't Christ supposed to return within the lifetimes of his disciples?
...Oh, okay, you're a Poe. Gotcha!
In response to your Additional Details: I don't "believe that God isn't real" -- I simply reject your claim that God IS real. I'm not saying your claim is impossible, but at the moment it has absolutely no power to persuade, so I don't believe it. The idea that God isn't real and there is no life after death is simply the null hypothesis, and claims to the contrary have not been presented with sufficient evidence to accept.
