I ran across this song some time ago. It is by no means new music, it's been out for years I think. It is Watermark singing "Light of the World." This is one of my favorites when it comes to Christian music. How interesting to think that even the best music we hear while on earth, will pale by comparison to God's Chorus in Heaven. That alone would be worth the price of admission in my book!
