They do seem to be saying that people alive at Armageddon have as good a chance of surviving as the billions who died beforehand. If they really mean that then it would mean billions surviving. Does that make any sense in view of everything else they teach about God and salvation? No, it doesn’t seem to make sense at all. But that is to state the problem, not to solve it.
It’s not they seem to be saying it, they are definitely saying it. there is no ambiguity in what they are saying here.
person’s eternal future does not depend on when he happens to die
Unrighteous ones have the same chance of being in paradise if they died beforehand or not.
It is clear they are saying there is no difference between those alive at Armageddon to everyone who has died throughout all of history. This is very very clearly the new light,
it is stupid new light, but it is definitely what they say. The earth is no way large enough for billions to survive Armageddon and then for many more billions to be resurrected.
