A Different Kind of Throne...

In those days a decree went out from Caesar Augustus that all the world should be registered. This was the first registration when Quirinius was governor of Syria. And all went to be registered, each to his own town. 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, to be registered with Mary, his betrothed, who was with child. And while they were there, the time came for her to give birth. 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.
(Luke 2:1-7 ESV)
Christ was at the Father's right hand.  Then He chose to come to earth. "Thou didst leave Thy throne..." we sing, and rightfully so.  At the incarnation, he chose another throne - the manger.  It may not look, or smell, like much, but it was still His throne, because that is where He chose to be.  To make it clear that this was a throne, The Father moved the shepherds to come and see, and worship Him.  It is not because the manger scene makes the perfect Hallmark card picture that things happened the way they did.  It is because the Lord, Savior and King, for a time, relocated to earth.  Wherever He is, is where His throne is.  He rules the world. Even though He has ascended back to the Father's right hand, He still is the King on the throne, over all.  That's what we recognize when we come to the manger.
