I will confess that I went to Youtube looking for Sufjan's version of this song and found this one hovering around it. Not to worry. Christmas is coming, and Sufjan will get his turn.
These guys intrigue me. When I listen to their music, I think either they have been greatly harmed by attempting a Christian walk, or greatly served by it. If their walk has been anything like mine, I will assume both.
These lyrics always get me:
"Prone to wander, Lord I feel it,
Prone to leave the God I love
here's my heart, Lord,
take and seal it.
Seal it for the courts above."
