Christmas is coming! That news may conjure mixed emotions for many of us as adults, but for the original hearers it was overwhelmingly wonderful news. When joy erupts in our lives that strongly, it often spills out of us in other ways. (There's a reason stores and radio stations start playing certain songs.) Repeatedly in the Gospel of Luke, the response was spontaneous songs of joy - from Zechariah, Mary, the angels and even Simeon. For the next four weeks, as we prepare to celebrate the Incarnation, we're going to reflect on the joy that led them to erupt in hymns of joy and deliverance. We begin this week with the Benedictus: "The Songs of Advent: Zechariah" (Luke 1:67-80).
