If someone who had never heard the story of Jesus were to ask about His origins, we would, I suspect, begin with the story of His annunciation and birth and end with the story of His resurrection and ascension. While that does capture His life, that’s not how the Gospels either begin or end His story. The story of Jesus and the meaning of Christmas can only really be understood by looking at where Jesus came from, His family tree, and by looking at how His story has continued in history. Indeed, that’s how the Gospels tell His story.
