The scripture tells us in Matthew 2, "After Jesus was born in Bethlehem in Judea, wise men from the east came to Jerusalem and asked, ‘Where is the one who has been born king of the Jews? We saw his star in the east and have come to worship him.’" In other words, the star was guiding them to this new Savior of the world. After Jesus started his ministry on earth, a star was no longer needed to direct people to him.
