Being a shepherd in biblical times was not necessarily an honorable occupation. They were viewed as nomadic people whose definition of personal property was extremely flexible. When the flocks packed up and moved on, so, often, did the possessions of local inhabitants. So untrustworthy were shepherds that their testimony could not be admitted as evidence in a court of law. They would have been the last people you would think of to entrust an important message. Yet that is what God did.
The first people to ever be entrusted with the Gospel message were shepherds. The angels could have made an announcement in the Roman palace or the courts of the temple or the meeting chamber of the Sanhedrin, but they did not. Heavenly messengers were dispatched to announce the amazing news to people who were considered least in their society.
And how did the shepherds respond? They glorified God. They gladly received the good news. They were filled with praise for what God had revealed to them. They knew full well that they had been entrusted with something extremely important. God is no respecter of persons. He loves each individual. He wants each one to know the incredible news of what He has done for them. He also allows us the amazing privilege of delivering that message on His behalf.
