Sufjan Stevens is not your typical Christian musician. The lyrics of this song are haunting and desperate. I imagine them to be about both the relationship between God and Jesus and our relationship with the two. A while back I was angry at God for creating us in a vacuum of the self. We are completely alone in this world without God in our lives and our ability to communicate with the divine is shaky at best rendering us almost to the level of orphaned. This song points out how much God wants us to be involved with him or her and how much Jesus gave up for out of shear love.
