Venerable Fulton Sheen offers us beautiful reflections on the mystery of the Incarnation as we approach that great solemnity:
A Jewish scholar who became a Christian and who knew the Old Testament very well and all of the traditions of the Jews, said that at the time of Christ the rabbis had gathered together 456 prophecies concerning the Messiah, the Christ, the conqueror of evil who was to be born and to enter into a new covenant with mankind. Suppose the chances of anyone prophecy being fulfilled by accident, say the place where he would be born, was one in a hundred.
Then, if two prophecies were fulfilled, the chances would be one in a thousand. If three prophecies were to coincide in Christ, that would be one in ten thousand. If four, one in a hundred thousand. If five, one in a million. Now if all of these prophecies were fulfilled in Christ, what would be the chance of them all concurring at the appointed moment, not only in place but also in time, as was foretold by the prophet Daniel? Take a pencil and write on a sheet of paper the numeral 1, and draw a line beneath it. Under the line write 84, and after 84, if you have time, write 126 zeros. That is the chance of all of the prophecies of Christ being fulfilled. It runs into millions and millions, trillions and trillions.

Mary is now with child, awaiting birth, and Joseph is full of expectancy as he enters the city of his own family. He searched for a place for the birth of him to whom heaven and earth belonged. Could it be that the Creator would not find room in his own creation? Certainly, thought Joseph, there would be room in the village inn. There was room for the rich; there was room for those who were clothed in soft garments; there was room for everyone who had a tip to give to the innkeeper.
But when finally the scrolls of history are completed down to the last word of time, the saddest line of all will be: "There was no room in the inn." No room in the inn, but there was room in the stable. The inn was the gathering place of public opinion, the focal point of the world's moods, the rendezvous of the worldly, the rallying place of the popular and the successful. But there's no room in the place where the world gathers. The stable is a place for outcasts, the ignored and the forgotten. The world might have expected the Son of God to be born in an inn; a stable would certainly be the last place in the world where one would look for him. The lesson is: divinity is always where you least expect to find it. So the Son of God made man is invited to enter into his own world through a back door.
