This is without a doubt my favorite Advent-Christmas hymn. I particularly revel in the gloriously delicate anti-Pelagianism in the third verse and the triumphant reversal of the course of history (a cheerful spirit of postmillennialism) in the fourth verse. This hymn bursts forth with joy over the First Advent of the Son upon whose shoulders the government now rests and the increase of whose government and peace shall never cease. I had to wade through a lot of contemporary pop-evangelical and pop-secular renditions (which are all okay in their own way) in order to find a traditional choral version (which wasn’t performed by Mormons, despite their impressive skills).
Indeed, joy to the world, because we have received the King who is not of this world but of the world to come, and our King has inaugurated his kingdom which is not of this world but of the world to come.
