Therefore the Lord himself will give you a sign. Look, the young woman is with child and shall bear a son, and shall name him Immanuel. (Isaiah 7:14)
We read about the dislocated people in the Nativity story. Mary was startled by the angel’s announcement of the Messiah’s coming into the world through her. Joseph was told a similar story in a dream, and both of them set off into strange, dangerous, history-making circumstances. The Wise Men followed a star across deserts and mountains to the Messiah’s manger-crib. Sheepherders in the fields—minding their own business!—received the news from a heavenly host. All these people were given signs; and all of them were given companions as they wondered and wandered.
This seems to be how God works: strangely, for sure, yet always compassionately aware of our need for human accompaniment, especially when experiencing divine revelation.
