Lyric discussion by the666thmessiah 

This song is about how the evil that people do will find them out:

"I am the sledgehammer messiah, waiting for sins to be born and if you stop for a moment you can hear the machines are playing your song" ~indicating that there is always a tally on the evil actions we perform, and there is an entity out there that will call us on it

"By cosmic retribution I've been sent Cause I'll rise, You'll fall Roll the dice! My call" ~Again, the chorus shows that the more we commit, the more likely we are to be called on the actions we perform

Of course the song might not be about a specific entity at all but rather the way the universe responds to our existance
