In the book of Acts, Luke shows how the Risen Jesus was exalted as the king of the world. Acts is about the story of Jesus leading His people by the Spirit to go out into the world, and invite all nations to live under His reign. And so the story begins with that message spreading in Jerusalem, and then into the neighboring regions of Judea and Samaria, full of non-Jewish people, and then from there, out to all the nations of the earth. Luke is saying that the new temple promised by the prophets, is Jesus’s new covenant family, the people of Jesus. And so we see Jesus’ Commission coming true.
