to be completely honest you guys are getting way to religious about this its, simply about a powerful king who was at the top, got betrayed and now he's at the bottom, and he thinks saint peter won't call his name because the things he's done "blew down the doors to let me in" and what he was when he got power, "people couldn't believe what i'd become". and on the chorus h talks about the good things that happened when he ruled the world (was the king).it was also in the roman times
