You inadvertently hit the nail on the head. This is the core difference between the believer (regardless of belief) and the non-believer. To me it's all about "what if" because the "what if" is the entire question. With all those sect of all those religions if only one is right my chances of picking the right one by chance are negligable, so I've got to study the situation and pick the right one through knowledge and understanding. Because according to most of the religions the what if that happens if I pick wrong is some form of eternal torment, what I still haven't figured out is exactly which eternal torment I'm trying to avoid, once I figure that one out I'll be most of the way to actually figuring which religion really is the one true religion.
I get the impression you've been talking to the wrong believers, if you've been talking to believers at all.
Because of sin, you are separated from G-d. By the sacrifice of Jesus your relationship with G-d is restored. I'm not asking you to avoid eternal torment, I'm offering you a chance to know a more beautiful love relationship than you have ever imagined because the G-d you enter into a relationship with is more beautiful than you have ever imagined.. Not some future relationship, but a relationship you can be a part of now. It starts today and goes on for eternity, getting better as it grows.
If there is an eternal torment, it is realizing that this relationship could have been yours, but you have rejected it.
Is a relationship like that something you would want?
Shalom.
