No, not everybody, but I'd say that in the LDS view, Heaven is much larger than it is to most Christians. And of course, you probably know by now that we believe that those who did not have a chance to hear, understand and accept the gospel of Jesus Christ during their lifetimes will have that opportunity before they are resurrected and stand before God to be judged.
Yes. I know that
quite well by now.
About that, I believe that when little children die, they go to Heaven, because they're unaccountable. They don't understand sin, and they don't know what God expects of them.
Wouldn't it be the same for a 14th-century American Indian who had (obviously) never heard the Word? They don't understand sin...they don't know what God expects of them. So how, then, could we say they were accountable and bound for Hell?
So, as you can see, I'm starting to believe that those who haven't heard the Word are unaccountable, and therefore going straight to Heaven. (Obviously not being a Mormon, I don't think they'll get that 2nd chance, so to speak, I believe they would just go straight there after their judgement.)
