I really don't think I'm right.. but..
i think that the song is about wanting to get away from somewhere, like a town, or a situation or something..
"This Town has its claws Buried in my neck This town- it takes lives Without Mercy Without Hate "
and if he stays there for too much longer it will be impossible to leave:
"I'm sinking Wont be long before I'm too deep to run"
OR in the lyric above, he could be talking about geting lost in lies that he's told, this lyric could also support that :
"The line up seems endless underneath the salvation signs"
Like that he's told so many that he doesn't know what to do, to make things right.
Like I said.. I don't know, that's my guess.
