Luke 2:1-7 In those days a decree went out from Caesar Augustus that all the world should be registered. (2) This was the first registration when Quirinius was governor of Syria. (3) And all went to be registered, each to his own town. (4) And Joseph also went up from Galilee, from the town of Nazareth, to Judea, to the city of David, which is called Bethlehem, because he was of the house and lineage of David, (5) to be registered with Mary, his betrothed, who was with child. (6) And while they were there, the time came for her to give birth. (7) And she gave birth to her firstborn son and wrapped him in swaddling cloths and laid him in a manger, because there was no place for them in the inn.
In those days. Those days are the height of Roman reach and power. They stretched from Britain to Parthia. Even Jerusalem had come under the power of the Romans and they were ruled by Quirinius. They were subject to this Roman census. God had ordained the world stage to move all the pieces into place in the fulfillment of prophecy. The power of Rome is used to bring about these events but these events would destroy the power of Rome. Dan 2:44 And in the days of those kings the God of heaven will set up a kingdom that shall never be destroyed, nor shall the kingdom be left to another people. It shall break in pieces all these kingdoms and bring them to an end, and it shall stand forever,
This new and heavenly kingdom began in the humble flesh of an infant boy. He had done it. God had emptied himself of glory. Later, on the night he would be betrayed Jesus would take off his robe and wash the feet of his disciples. This act would be a reenactment of this humility. He has disrobed himself of glory and come to serve those he would lead. The miracle of this birth: John 1:14 And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.
