On this Christmas Eve, we celebrate the birth of Jesus Christ, who came to the world as fully God and fully man. Yet centuries before the birth of the Messiah, there was no person to declare, “Behold the lamb of God, who takes away the sin of the world!” (John 1:29). There was only an expectation of God’s promise, with some prophetic puzzle pieces that could not be truly assembled without the full revelation of Jesus Christ. However, that expectation had fallen into deep depression during the Babylonian captivity.
