O. K. You both have pretty good opinions on what the song is about, but. Take into account the name of this song and how this band are Christian. They speak of comfort, complacency and how staying dependent to this comfort will ultimately lead you to hell. The lyrics state that the singer almost let comfort (here personified as a being) destroy him/her, and that even though comfort may seem like a great friend, in the end, it betrays and will destroy you.
