The only invitation from God to anyone to come and visit Mary and Joseph and the infant Jesus is to a group of shepherds. They were common people on the bottom of the social ladder of the day, perhaps the last people that you’d expect God to send as the first VIP guests to see His Son.
The shepherds represented Jesus’ identity as a descendent of King David, who was also a shepherd. They also remind us that Jesus was the sacrificial lamb. Because of the Messiah’s perfect life and death, we have a restored relationship with God.
