"But the angel said to them, 'Don't be afraid, for look, I proclaim to you good news of great joy that will be for all the people: Today a Savior, who is Messiah the Lord, was born to you in the city of David. This will be a sign for you: You will find the baby wrapped snugly in cloth and lying in a feeding trough" (Luke 2:10-12, HCSB).
It's pretty cool that God chose these shepherds to hear the Good News of the Messiah's birth. God must have seen something in their hearts, something that showed a willingness to move and act, a willingness to believe that the Messiah had finally come. They must have felt such confusion, but also, such excitement when they heard the angels' words! Being visited by an angel wasn't really an everyday occurrence then, or even now. It was unique, it demanded attention. Something important was happening. The long awaited Messiah had come. Not charging in on royal steed, dressed in purple, ready to save the Israelites from their oppression, but as a tiny baby. A tiny baby born into a poor family, who had no place to lay in other than a manger. So small. So humble. So accessible to the shepherds out in the field. So approachable. So... exactly how God had planned.
