The thing that's always bugged me the most about predicting the end of the world (besides the zillion times it's been wrong) is that the kind of God who'd blow up the world and make everybody's last days full of pain and suck is, by definition, a bad guy. Which sorta works for the early Old Testament God that's all "Sacrifice your kid! Flood the world! Knock down those walls and kill everyone inside!" but is pretty out of character for most non-vengeful turbolaser versions of Jesus. So, yes, a lot of these prophecies are bad biblical fanfic.
Of course, Fred's already covered this over at
slacktivist with "goofy hat Jesus".
Oh, and no, the world's not going to end tomorrow. We'll still be here for my regularly non-updating blog. But just in case it does, I'm gonna be out where things are fallen down and trying to fix them, and rescue people. Because that's what good guys do. They don't sit back and laugh at other people's misery.
