I do not want to make this a complicated situation. IMO, you are making it that way, based on your posts... Which are very interesting, yet at the same time, I can't help but shake my head and say, "But if you believed in God, you wouldn't do that, so what the hell?". In other words, you have to make up your mind sometime, ledlead. I know you are happy this way, I'm sure you are indifferent about God's presence and all. I can tell you are an Agnostic Theist, which is err, "fine." You just like to sit on the fence. I don't really want to change your stance by making you rationalize things further right now, but just think about one last thing: Why do you believe your god to be the one true god out of all gods that are out there? Why not be part of all religions, since you'd rather feel secure knowing that you are going to the afterlife?
Personally, there is no afterlife. It's very simple. Your existence and state of mind stop when your brain stops. Everything stops. You simply die, and thinking of an afterlife to me is just a fairytale to tell the kiddies that they will be safe when they die. Obviously, I'd tell them the actual truth as to what happens when they die, but if that's what they want to believe as a silly kid thing, that's fine, too, just like the whole Santa Claus and the North Pole thing. It doesn't make me a less happy person to know that eventually, I will die, and so will everyone else. Thinking that they, or myself, are going to be in a better place is silly, and a bit insulting, IMO, because saying it's God's plan means their whole entire lives where planned out, only a pawn in this plane of existence.
I feel safer to know that when I die, I'll know I had a good life, I tried to live it to the best of my capabilities, I enjoyed the ride, and that I'll forever be rid of suffering and finally rest in peace. Being immortal is not something humans would like, because it is human nature to get bored and even go crazy if something like that were to happen. Humans, and all living organisms, are meant to die. It's the proper order of things. An afterlife sounds like a nightmare. IMO, if there were hell, being immortal would be the punishment.
