We do this when we open our presents...
...as a reminder that Christmas is not all about this.
It's easy to get caught up in the getting. Especially when you are a child and the whole house changes. The tree is so front and center. All the packages under it are so front and center. But there is another deeper reason we celebrate Christmas.
Now in those days a decree went out from Caesar Augustus, that a census be taken of all the inhabited earth. This was the first census taken while Quirinius was governor of Syria. And everyone was on his way to register for the census, each to his own city. Joseph also went up from Galilee, from the city of Nazareth, to Judea, to the city of David which is called Bethlehem, because he was of the house and family of David, in order to register along with Mary, who was engaged to him, and was with child.While they were there, the days were completed for her to give birth.And she gave birth to her firstborn son; and she wrapped Him in cloths, and laid Him in a manger, because there was no room for them in the inn. In the same region there were some shepherds staying out in the fields and keeping watch over their flock by night. And an angel of the Lord suddenly stood before them, and the glory of the Lord shone around them; and they were terribly frightened.
But the angel said to them, "Do not be afraid; for behold, I bring you good news of great joy which will be for all the people; for today in the city of David there has been born for you a Savior, who is Christ the Lord." ~Luke 2
