Well that doesn't fit in the bible at all. So we're going full pop-culture on this one? And who would free, y'know, the devil?

And we'd just be standard humans? Your OP implied we'd be able to be in hell, heaven, OR earth. Or is that just a 'side' for us to pick on? And realistically, god is said to be a literally all powerful being: what actual chances do the others have?
