Jesus, in "The Nativity Story", is described as someone divine, from heaven, as the Messiah, or the Savior. He is the son of God, and often times described as the King of Kings, as someone that stood above all others. The scriptures, songs and stories and even the movie, all serve to exemplify and reiterate these titles. In the christmas carol. "Away in a manger" The first lines of the thirds stanza goes,
"
The cattle are lowing
The poor baby wakes
"
This serves to illustrate where he was born. And it was in a very humble manger. To think that the son of God was born in such a place, as a baby, is mind blowing. It is as though his love for us, was shown through putting himself in such a lowly position. Mary and Joseph, as were shown in the nativity, were required to accept. Accept the events that were being thrown at them such as Mary's immaculate conception as well as their journey all the way to Jerusalem. This same thing was required of the astrologers and shepherds. And it was to accept that such a thing was happening, and that it was not some big coincidence. But because they did accept, the story was able to play out as it did. As I said, Jesus was the Messiah, the Lord, The King of Kings, the Lord of Lords, and was equal with God. Jesus, however, came down. And this shows several things about him. It shows that he loves us. But not only that, it shows a type of God that is willing to approach his people in a non-threatening, non-forceful yet loving and kind way. And it is because it is non-forceful that it would be the right way for God to come to his people anyways, because he wants us to love him back, not just be forced to worship him.
