In the drama of the incarnation, Jesus is, of course, the star. That’s the way it is at every birth. All eyes are on the baby. The co-star, though, is definitely mom. Without her love and labor, the event could not have happened. In this case, without mom’s faith it couldn’t have happened either. According to Luke’s Gospel, an angel brought her stunning news. She believed the unbelievable and said “let it be.”
But there is a best supporting actor in the drama as well. True, Joseph was not the biological father. But the messiah had to be of David’s royal line. In ancient Israel, a child’s clan was determined by that of his father. So it was Joseph who legally bound Jesus to the house of David. It was because of Joseph that the family had to go to Bethlehem for the census, that the prophecy might be fulfilled.

For genes are not the only thing parents impart to their children. Jesus, in his humanity, had to grow in wisdom, age, and grace (Luke 2:52). Joseph must have responsible for a good deal of this growth. It was Joseph who was Jesus’ male role model. From Joseph Jesus learned many things, including the trade that he would practice for some twenty years.
