Luke 2:8-20 (CSB)

The story of the shepherds highlights the gospel’s appeal to everyone. The shepherds, an unlikely group viewed as outcasts, untrustworthy often labeled as criminals had no influence or power. Yet, this is the group God selected to reach out to in the fields in a spectacular way. 

We see them being obedient by immediately going to see the newborn King and spreading the good news  which made them first missionaries of the gospel! God calls everyone regardless of affiliation, past or societal standing. The gospel is for everyone.
