No need to waste time reading the hundreds of Left Behind books, or even the Bible. The answers are all right here.
I kid the Left Behinders, yet find myself enjoying economic doomsayers like the Golden Jackass entirely too much (and what's not to love about the 1st generation Nintendo console animated donkey gif?). I understand the appeal of wanting the world to end soon, as apparently most conservative Christians do. If it turns out you don't get to live for all eternity after all, the obvious selfish reflex is to want everybody else in the Universe to die at the exact same time you do. Otherwise somebody might be getting a better deal than you.
