I believe that this song is about a soldier beginning to question why he is fighting and what it is all for. The lyrics do say that God is on our side, but the following line should lead you to believe that he is telling himself this to justify the fighting in his own mind because of the fact that he can't have any physical evidence of any real reason as to why. This is an amazing song, but sometimes you have to look deeper into the song, or learn a little more about the band/singer to understand the meaning to some songs.
