Is this a Pascal's wager decision, or do you have other reasons for believing in an afterlife?
If you do believe there is an afterlife, how do you envision it - do people go to some type of heaven/hell, do some people just not get one? What proportion (approximate!) of people either get an afterlife (if not everyone does), or get a happy one (if everyone gets something) - in your mind, is it "very difficult" (i.e. only the very pious), or is a general life of being "good" (whatever that means) sufficient?
I have no judgment on this, just curious to learn more about a belief system that varies so differently from mine. Personally, I don't think there is anything after you're in the ground, nothing good or bad, no immortal soul in our bodies, etc. But that's my opinion only, and I don't begrudge others who feel differently. It's unknowable and some of the smartest people I know have different opinions on it than me.
I have to believe in some sort of afterlife. Whether it is going to a place, or reincarnation
Watever happens I do believe God is fair. Say for example that christianity is true, isn it really fair for someone raised in a contrary faith to be judged the same as one who is raised in a christian family? Maybe as one philosopher once said, "There are many mountain tops and they are all reaching for the stars".
