This is what it says on Jesusfreakhideout.com about this song:
Behind the Song:
“Mystery of You” examines an emotionally war-torn soul looking for answers. Over a stream of loops and keys, singer Michael Barnes pines, “You always said you'd be here/Where are you now?” and the sobering “Don't leave me all alone.” With its deep melodies and climactic chorus, “Mystery of You” is ultimately less about the fear of being alone and more about recognizing that some mysteries can only be revealed beyond this life.
