The sermon is based on Luke 2:8-14 (CEB)
Announcement to shepherds
8 Nearby shepherds were living in the fields, guarding their sheep at night. 9 The Lord’s angel stood before them, the Lord’s glory shone around them, and they were terrified.
10 The angel said, “Don’t be afraid! Look! I bring good news to you—wonderful, joyous news for all people. 11 Your savior is born today in David’s city. He is Christ the Lord. 12 This is a sign for you: you will find a newborn baby wrapped snugly and lying in a manger.” 13 Suddenly a great assembly of the heavenly forces was with the angel praising God. They said, 14 “Glory to God in heaven, and on earth peace among those whom he favors.”
