When the angel of the Lord appeared, the glory of the Lord surrounded the shepherds. They were afraid, but the angel brought good tidings which changed their fear to joy. The angel said the joy was for all people, and the source of the joy was the baby Jesus.
Not only did the angel tell the shepherds about Jesus, the angel told them how to find Jesus. Our mission is to tell people the story of Jesus so that their fears can be turned to joy. We can share the story and then also tell people how to find Jesus for themselves.
Jesus came to give us life more than abundant. He modeled the perfect life, He paid the perfect price for our sins, and He gives us perfect joy through His resurrection.
