There's actually a great book series written like a religious sci-fi series that really portrays how shit would play out in real life, it's by Wendy Alec if you like that sort of thing. Interestingly enough it involves a fake pandemic and forced vaccinations, internment camps, fake body bags, the whole works. My understanding from reading the bible is Jesus comes like a thief in the night. Bible describes how there will be two people sleeping in bed, one will be gone. Two people working in the fields and one disappears. I think, and I may be wrong, that this is the rapture where God's children, His faithful, are taken up. Anyone who isn't taken up is in for one hell of a shit show. Armageddon, reckoning, the final battle. But I am no bible scholar, just a simple anon.
