God has deemed the ENTIRETY of humanity unworthy.
Not a single soul will be raptured to heaven on May 21st. Of all of the six-or-however-many-billion of us there are on the planet, the Almighty has determined that we are all individually and collectively a bunch of LOSERS.
Rapture WILL come and pass, but with nobody raptured anywhere on the planet, we will mistake the EVENT OF THE AGES as a non-event.
The Lord is also reportedly regretting having previously stated that animal companions (aka pets) would not be raptured, facing as He is the lack of a single golden retriever or calico, nay nary even a goldfish, with whom to spend the rest of all eternity.
(Believe me, if you had to spend eternity with that annoying ArchAngel Micheal, always preening his wings and dancing on the head of a pin like the vain show-off he is, you'd be longing for the companionship of a goldfish as well.)
On that Fated Date of May 21st, when zero humans are being raptured, an intense string of tornadoes will hit the industrial feedlots and chicken houses of the south and midwest, resulting in cows and chickens sucked into the air by the thousands. Confused evangelicals, witnessing this, will be unable to reconcile the observed-presumed fact that heifers and poultry are being raptured, yet they are not (in reality, aforementioned cows and chickens won't really be ratpured {see above} but merely deposited in the neighboring county, back here on earth.) As a side-effect, a strange new cult of cattle and poultry worshiping evangelicals will arise in these areas. Not that these creatures will no longer be inhumanely raised and slaughtered, mind you; rather, the feedlots and slaughter-houses will bizarrely become their new temples, and they will splash themselves with the blood of the Cow and the Chicken, (now written in All Capitals as the True Chosen Ones of God)
As for Jubilee, what a bummer of a party that's going to be for God. He's rented all these white (of course) tents, punch bowls, and folding chairs, and now He's going to look like a fool sitting at the center of the head table, all alone with the insufferable Michael by his side.
And the booze bill, simply staggering. (I know, it's a little contradictory, God having spent millions on the bar to toast the supposedly faithful, whom one would more typically suspect to be tea-totalers; but one supposes that He figured a few of the faithful would want to let loose just a little after their lives of (supposed, but now shown to be false) devotion.
So here's God, alone (save that damned Michael - well, God would damn well damn Michael to You-Know-Where if HE could, but since he's already played that card once - with Lucifer, that's no longer an option.)
What is The Almighty to do in such a situation? The Rapture has come and past, and ZERO have been raptured, what should God do?
Of course, stick with Plan A:
BRING ON THE TRIBULATIONS.
Fire, Famine, War, Drought, Flood, Plagues, Disease, Satan's Kingdom on Earth (TM), etc.
In other words, May 22 will be pretty much like May 20th and 21st, and May 23rd as well. Call it just another day in eternity for God.
