I'm going to be blunt, You made a poor choice! Not only might you go to hell, but if you find yourself "left behind" or not surrounded by Christians, then you're most certainly going to be surrounded by nasty people; who really don't care whether you live or die. And, your future, well; I wouldn't give a bucket of piss for it. 

You need Jesus! I need Jesus. And without God's help, no matter how much you prepare, you won't be ready for what's coming!
