DeeGee » Has anyone been back from the dead and personally told you about their conversation with God, what he/she said to God and vice versa, and provided you with the details of what the afterlife is like?
That's kind of the whole question about religion, isn't it? And how we face our own demise is central to it all. The JWs most also experience some apprehension when they die as well, because they, too, face a void...a cessation of existence. If there really is a soul sleep, a person will literally cease to exist, never to exist again. Jehovah may reconstruct someone, reconstruct their memories -- the person may even look the same and feel the same -- but all they can expect to be is a carbon copy. Jehovah could crank out two more of them without breaking a sweat! But none would be the same exact person and all three would swear they were the originals (and in a sense they'd all be right...and wrong).
Intelligence would have to be constant to be eternal. God could take all your original particles and recreate you bit by bit, atom by atom, and you still would be only a copy.
The entire idea behind religion is revelation. People don't all experience life after life revelations, nor do they all see God. But it's far too simplified to say that all prophets are con men and that all those who believe them are fools. Con men aren't usually willing to die for their cons and many religionists have been shown to be some of the most brilliant thinkers and writers in world history.
Whether created or the products of generations of evolution, man has some internal need for religion. And many early prophets weren't one-man bands. They had witnesses. Moses had a meal prepared for seventy elders, all of which "saw the God of Israel." So whether the account is true or false, the ancient God of the Hebrews wasn't hidden as many other gods of the world. So it's not a reach to ask whether non-believers might have doubts on their deathbeds, a time when they have to face their own mortality.
