It may be Mustard Seeds, although it doesn't sound like it, because they refer to faith being the size of a Mustard seed often in the Bible to describe the faithless. Not sure what that has to do with the song, this man seems to have very much faith. Also I second the baby-ankle line, I keep hearing baby.
