During the Christmas season or "advent" Christians all over the world celebrate the wondrous miracle that our God became a human being in the person of Jesus Christ of Nazareth. But why did he need to become a man? Why was it essential for him to actually live?

So why did Jesus have to live? This Christmas season we explore what the Old Testament has to say about the need for God to become a man.
