The story is about a shepherd boy (Tommy) who is tending the sheep when the angels appear to tell them about the birth of Jesus. He goes and gets his older brothers (who always make him pull the night watch because they can). They all hear the message and want to go, but Tommy realizes that someone needs to stay with the sheep. He volunteers to stay behind.
The brothers go to Bethlehem and see the baby Jesus in the stable (all to a musical interlude).
While they are there, Jesus appears to Tommy back in the field and promises that someday he will be a “shepherd of people” because of his faithfulness.
The next act skips forward many years to when Tommy is now grown. He is in Capernaum and has been diligent in studying the Scriptures. He hears about a man who teaches with authority and can heal people. Tommy comes to see if he is the one who appeared to him that night in the field. It is Jesus and Jesus calls him to follow him.
The narrator does a quick synopsis of Jesus’ ministry and what the disciples’ experience was. Then there is a brief portrayal of the Last Supper, Gethsemane, and the Crucifixion.
The story picks up again with the disciples coming to get Tommy because Jesus has appeared to them. Tommy doesn’t believe it. Then there is the scene in the locked room where Jesus appears to Thomas. Thomas now believes and sends him out to be a shepherd in the church—to lead, guide, protect, inspire, nurture the believers.
