I believe the meaning of this song is that any person can be corupted when they obtain even a small amount of power like when the singer sang (I know saint peter won't call my name) possibly stateing the person has been corrupted it also seems they say someone can be saved by being forgiven as stated when the singer sang (i know saint peter will call my name) I believe the song simbly states anybody can be saved from their own corruptioun.
