Jesus did not embody the personal qualifications of the Messiah.
A. MESSIAH AS PROPHET Jesus was not a prophet. Prophecy can only exist in Israel when the land is inhabited by a majority of world Jewry. During the time of Ezra (circa 300 BCE), when the majority of Jews refused to move from Babylon to Israel, prophecy ended upon the death of the last prophets -- Haggai, Zechariah and Malachi.
Jesus appeared on the scene approximately 350 years after prophecy had ended.
b. DESCENDENT OF DAVID The Messiah must be descended on his father's side from King David (see Genesis 49:10 and Isaiah 11:1). According to the Christian claim that Jesus was the product of a virgin birth, he had no father -- and thus could not have possibly fulfilled the messianic requirement of being descended on his father's side from King David!
c. TORAH OBSERVANCE The Messiah will lead the Jewish people to full Torah observance. The Torah states that all mitzvot remain binding forever, and anyone coming to change the Torah is immediately identified as a false prophet. (Deut. 13:1-4)
Throughout the New Testament, Jesus contradicts the Torah and states that its commandments are no longer applicable. (see John 1:45 and 9:16, Acts 3:22 and 7:37)
