Luke stresses the fact that Jesus was born in Bethlehem because Joseph, his father, was of David's House and line, and Bethlehem was David's town. So Joseph set out to that town in Judaea in order to be registered in the census ordered by Caesar Augustus, together with Mary who was with child. While they were there, the time came for her to have her child and she gave birth to a son, her first-born. But, what is the religious significance/meaning of the fact that Jesus was born in Bethlehem? Why does Luke stress the fact that Jesus was born in Bethlehem?
A clue: Read this text of the Gospel of Luke 2,1-7:
"Now it happened that at this time Caesar Augustus issued a decree that a census should be made of the whole inhabited world. This census -the first- took place while Quirinus was governor of Syria, and everyone went to be registered, each to his own town. So Joseph set out from the town of Nazareth in Galilee for Judaea, to David's town called Bethlehem, since he was of David's House and line, in order to be registered together with Mary, his betrothed, who was with child. Now it happened that, while they were there, the time came for her to have her child, and she gave birth to a son, her first-born. She wrapped him in swaddling clothes and laid him in a manger, because there was no room for them in the living-space." Another clue: Look at this painting by Fra ANGELICO, dated from 1441, that is the St Mark's National Museum in Florence, Italy.
