I think this is a song against all those "pentecostal" hypocrite church leaders who use Jesus Christ as an excuse to dominate week-minded people who they fill their churches with. Every time anyone tries to suggest a meaningful interpretation of a message from a spiritual sage in the context of the times these charismatic Church leaders slap us down and tell us that we must not think but only believe the way they want us to believe. "I feel so alive here" is sarcasm, it means "I might as well be dead". They have left a bitter tase in our mouths.
So as a result of the verbal defecation they spill out over "lost deamons" like us "condemned to hell", we are about to become what they accuse us of being -the scourge of God sent on Ragnarok to purge the world of its hypocrisy. The Macabrim who alone have the power to bury the armies of Gog.
