As you read the Christmas story from Luke this Christmas, consider the words written by Darrell Bock in his commentary on Luke:
Luke 2:1-21 portrays Jesus’ birth with a simplicity that belies the event’s universal significance. The birth of the Davidic Savior and Messiah occurs in a room normally reserved fro animals. His crib is a feed trough. And yet the birth in Bethlehem is the beginning of the fulfillment of God’s most significant act for humans. From this simple setting emerges the Lord Jesus, the focus of all God’s promises and of all human hopes.
In Luke 2:11, Jesus’ life is introduced in terms of three titles: Savior points to his role as deliverer; Messiah points to his office in terms of the promised Anointed One of God; and Lord indicates his sovereign authority.
Jesus’ birth is set in the middle of Roman history, in the reign of Caesar Augustus, However, for Luke the key historical figure is not the powerful Roman ruler; it is the frail child, Jesus, the Christ, who is Lord.
In the angelic exchange with the shepherds, the major point is heaven’s testimony to simple folk. The shepherds seem to represent humankind. After hearing angelic testimony of heaven’s joy over the birth, they respond admirably and go to see the child. They share the joy of heaven upon fulfillment of the word. The see, hear, and testify. Other bystander at the event marvel at what is happening as the birth produces a variety of responses. In Jesus, heaven and earth come together.
