Yeah. So they can continue on doing whatever they want without having to face the apocalyptic consequences here when it hits. They're chosen.
Of course, the math ain't mathing. They conveniently gloss over that part. If we're to take Revelations literally, it's something like 145K or 172K across all of time, since Adam, that get raptured. I can't remember the number, exactly; I'd have to look it up again. Everyone else, still alive, faces the Tribulation. The dead await Judgement Day.
So the odds are not in their favor.
Whether you believe in the literal interpretation of the Bible, or not, or are an atheist ....it's completely reckless and decidedly un-Jesus-like thinking.
But it makes you feel really good while the world burns around you. Ah, the sweet sweet smell of cognitive dissonance. Smells like candy corn.
