C.J. Mahaney reflects on this thought in a recent post. In part ::
During this time of year, it may be easy to forget that the bigger purpose behind Bethlehem was Calvary. But the purpose of the manger was realized in the horrors of the cross. The purpose of his birth was his death.
Or to put it more personally: Christmas is necessary because I am a sinner. The incarnation reminds us of our desperate condition before a holy God.
He then quotes extensively from William H. Smith ::
Many people who otherwise ignore God and the church have some religious feeling, or feel they ought to, at this time of the year. So they make their way to a church service or Christmas program. And when they go, they come away feeling vaguely warmed or at least better for having gone, but not disturbed.
Why aren’t people disturbed by Christmas? One reason is our tendency to sanitize the birth narratives. We romanticize the story of Mary and Joseph rather than deal with the painful dilemma they faced when the Lord chose Mary to be the virgin who would conceive her child by the power of the Holy Spirit. We beautify the birth scene, not coming to terms with the stench of the stable, the poverty of the parents, the hostility of Herod. Don’t miss my point. There is something truly comforting and warming about the Christmas story, but it comes from understanding the reality, not from denying it.
