Reminds me of Simeon in Bethlehem (which is one of my four favorite songs).Something I noticed from the radio and previews and whatnot.....a few of the songs seem to be "perspective songs"
I AM is from God's perspective, He's talking about Himself in 1st person
Nailed is from Martin Luther's perspective
Altar to the Unknown God is from Paul's perspective
Drown seems to be from Peter's perspective (at least the samples I've heard of it)
