This one is about compromising one's own convictions and the destruction it brings, provided they are the right sort of convictions.
The chorus is pretty straight forward. I admit that I have in, a sense, died morally.
The pre-chorus talks about me pretty much digging my own grave by continuously ignoring my convictions and the consequences of ignoring them. In the end, I join those who's convictions are long gone.
The chorus is actually me lecturing myself with slight admittance that I fell into the seduction of this world and it's way. Damnation may seem like a strong word and a little extreme, but once we've lost all senses of righteousness, we've banished ourselves from the convictions that kept us on the right track.
The second verse is basically just me realizing that I've messed up and wondering if there is even a way back at all.
The extended chorus furthers the lecture, saying that I will "feel the surge of divine wrath." What I mean by this is the feeling of spiritual pain and guilt felt afterwards.
All it takes to pull ourselves out of the destruction is one simple choice; to choose to step back and think things over before acting.
In conclusion, take into consideration your convictions before you take a step too far. It could possibly save you from the heartache and chaos that could destroy you for life.
