Since the fall of Adam, the Prophets, Temple priests and the entire world is looking towards Israel for the redemption of mankind. Few centuries later, prophet Isaiah writes in his scroll about a Messiah with a mysterious letter which they roughly translate as Immanuel and states that he will be born of a virgin.
So everyone including Lucifer is looking for the man born of a virgin and named Immanuel. But a rabbi named Yahushua rises in influence and claims to be the Messiah.
Meanwhile Lucifer hire a man named Judas to help him ascertain if he is truly the one they are expecting. Everything matches the description of the Messiah except for the name. Was he really the Messiah or is there anyone more to come? This man named Yahushua was called as JESUS CHRIST, THE KING OF THE JEWS by the Romans later on.
