So it is that the Birth of Jesus in the city of David has not one hint of accident about it. It was fully planned by God, the way paved by God, and consummated by Mary and Joseph whose desire was to cooperate fully with God. Once again, Mary (and Joseph) said yes. Yes to a long, difficult, and harrowing journey while far along in her pregnancy. Yes to separation from family and friends who could help and support at the birth. Yes to uncertain and rugged lodging both on the way and on their arrival. And yes to many, many other things as well, all because God had asked it of her. The Messiah must be born in Bethlehem and so she must go to Bethlehem with Joseph.
