One of the standard complaints heard at Christmas time is that it is getting more and more expensive to celebrate this holiday. But I recognize that the answer to this question depends on one's point of view.
Lets look at what it cost.
It cost Mary and Joseph the comforts of their home during a journey to Bethlehem. And then once again, when the angel directed them into exile in Egypt to protect the Christ child from the wrath of Herod it cost them. It cost mothers and father in and around Bethlehem the massacre of their babies by the wicked Herod. It cost the shepherds the neglect of the shepherd's life for a journey to Bethlehem to see the thing the Lord had made know to them by angels. It cost the wise men a long journey, expensive gifts of gold, frankincense, and myrrh.
