I felt that, for Christmas, a song celebrating the holiday was in order.
In 1985, the world changed. Christian pop superstar Amy Grant released an album - Unguarded - that had some secular success - and it made the sales of ALL her albums go up. That INCLUDED her 1983 A Christmas Album, which finally broke through in 1985. In fact, I believe I brought the album myself in 1985.
This song - written by Michael W. Smith - was the single from that Christmas album, and ended up being something of a holiday hit as well. It is clearly a song about, well, the son of God (Matthew 1:23). It is quite celebratory, and joyous, without getting overtly preachy or melancholic. It remains one of my favorite religious songs to this day.
