It's very interesting to contrast the two "annunciations" we find in the 1st chapter of Luke's Gospel. The announcement of the conception and birth of John the Baptist is made in a very religious context: To a priest who is ministering at the Holy of Holies in the Temple in Jerusalem. Far more surprising and unexpected (and powerful) is the announcement of the conception of God-in-the-flesh, which occurs in a much more ordinary and less overtly religious scenario: To a young woman in Nazareth, a podunk town in "Galilee of the Gentiles". This is a good reminder to us that in Jesus God enters time and space and makes the most ordinary extraordinary. Are we waiting for Him and expecting Him to do that?
