Well, no one else has shown up fulfilling the words of the prophets like he did... Isaiah 7:14 states he will be born of a virgin, Micah 5:2 was recognized by all the old rabbis of Jesus' time as a prophetical verse referring to the messiah... it placed Bethlehem as his place of origin. Isaiah 53, the whole chapter so perfectly describes the mission of Jesus as to be called "the Gospel of Isaiah"; and all these were written around 760 B.C !!!
