This is one of my favorite Christmas songs. It's by Point of Grace, but I wasn't able to find a youtube of them that I could embed here. (I have their album "A Christmas Story" which is where the song is from, and I heartily recommend it.) Anyway, this is a rendition done by some sisters in a church...I don't know who they are or where they're from, but they do the song justice.
One king held the frankincense One king held the myrrh One king held the purest gold... and One King held the hope of the world
