The announcement of Jesus Christ's birth carries profound significance, as conveyed by the angel to the shepherds. The angel declares that a Savior, who is Christ the Lord, is born in the city of David, linking His arrival to ancient prophecies. This title, likely expressed as Messiah Adonai in the Aramaic spoken by the shepherds, underscores that this newborn is not merely a special child but God Himself born as a human being. The sudden appearance of a multitude of the heavenly host, praising God with the hymn "Glory to God in the highest, and on earth peace, goodwill toward men," amplifies the importance of this event. Their presence and song reflect the immense joy and the significant step in God's purpose, as the great Captain of the heavenly host has been born. This birth initiates the process of bringing true peace to the earth, first through His sacrifice to reconcile God and sinful man, and ultimately through His return in glory to establish lasting peace.
