What I don't accept is you beating around the bush but I think with this post we can put together what you're trying to say. Your god isn't kind and or fair. According to you these indigenous people who have never heard of Jesus are condemned because they never had a chance to put all their chips on a human. By that same logic babies and kids are also condemned. Floss, you're not a very good missionary lol.
I don't think the Bible answers everything. For example, I think the Bible basically leaves you with no idea what exactly heaven is like. And I think you've brought up another unanswered question- what about people who never heard about Jesus? I have no idea. My guess would be that maybe God decides on a case-by-case basis regarding them.
I don't necessarily think that we have all the answers regarding who goes where in the afterlife. For example, if someone is a sincere follower of another religion and they honestly don't realize that Christianity is the truth, I don't necessarily think they go to hell.
I do believe Christianity is the true religion but I don't think anyone really knows exactly what happens after we leave. But if I'm on my deathbed and I have to put my chips on anyone, I'm putting all my chips on Jesus. As I do now.
