Zager and Evans rather depressingly assert that we’ll still be waiting for Judgement Day in 5000 years’ time. God, it seems, moves in ways that mysterious and ineffable, but above all, slow.
To be fair, Z&E also set this point as a deadline for God, and state that if he hasn’t made it be then, he might as well not bother, and we should stop waiting for him.
If they’re right, it would seem that there would never be a Rapture, which may or may not be good thing, depending on your beliefs.
