Joseph and Mary and the Command

Caesar Augustus was the emperor of Rome during the time shortly before the birth of Jesus, and commanded that a census be taken of all the people of the world. Everyone had to go to their own city to register, including Mary, who was engaged to Joseph.

And Joseph also went up from Galilee, from the city of Nazareth, to Judea, to the city of David, which is called Bethlehem, because he was of the house and family of David.
– Luke 2:4

Insofar as Caesar Augustus had commanded the census to be taken, he had only fulfilled the will of the Father in Heaven, who had commanded that all things be set in their proper place for the arrival of his Son.

But when the fullness of the time came, God sent forth his Son, born of a woman, born under the Law.
– Galatians 4:4

While the Heavenly Father took care of the arrival of Jesus into the world, so he sends the Holy Spirit to all newborn members of the family of God. The Holy Spirit teaches us to be obedient to the commands of Jesus, just as Jesus was to the commands of his Father. There is especially one command from Jesus that all believers would do well to follow, a command Jesus gave to his disciples;

“This is my commandment, that you love one another, just as I have loved you.”
– John 15:12
