Bethlehem was more or less remarkable for its proximity to Jerusalem as well as the birthplace of David. All well and good, but nothing had been happening now, for literally centuries, nothing lasting.
In comes that mysterious, glorious night when in God's providential working, the son of David, Jesus is born. Announced to the shepherds in a majestic display by angels, what had been listless (my guess) was now buzzing with hope.
I find in my experience I can so easily become listless. But like the shepherds of old, I have to remind myself what God's word already tells us: "Look to Jesus; come and see. Keep looking, and then learn to follow. And keep following no matter what."
If we have our eyes of faith open, which by the way are opened by simple faith in God's word, then we'll come alive in this new hope and reality found in Jesus. And we'll want to tell others so they can share it with us. We'll no longer be listless in a sleepy existence, but awake and alert and eager for what God wants to do and is doing- God's will in Christ Jesus. And we need to keep doing this.
