Answer 2

Lets see what the Tankah says the Mashiach will achieve: In the Messianic era there is peace In the Messianic era there is no poverty In the Messianic era there is no disease In the Messianic era the dead are resurrected In the Messianic era all the Jews are gathered in Israel In the Messianic era all the nations of the world acknowledge the holiness of the Jews and look to them for guidance Lets see which of those Jesus fulfilled: See the problem? Nowhere does the Tanakh discuss the Pagan concept of G-d having children and then walking around doing miracles. It does discuss a person with a human father and a human mother being the vehicle (The Mashiach) through which G-d will work to fulfill the above prophecies. And what are the requirements for the Mashiach: a Jewish mother since without that he is not Jewish; A Jewish father from the House of David without which he cannot be from the house of David; to be a righteous Jew- which Jesus was not since 1) he failed to fulfill the mitzva (commandment) of p'ru urevu (be fruitful and mulitply) and 2) he told his followers it was ok to break the Shabbo * The Sanhedrin will be re-established (Isaiah 1:26) * Once he is King, leaders of other nations will look to him for guidance. (Isaiah 2:4) * The whole world will worship the One God of Israel (Isaiah 2:17) * He will be descended from King David (Isaiah 11:1) via King Solomon (1 Chron. 22:8-10) * The Moshiach will be a man of this world, an observant Jew with "fear of God" (Isaiah 11:2) * Evil and tyranny will not be able to stand before his leadership (Isaiah 11:4) * Knowledge of God will fill the world (Isaiah 11:9) * He will include and attract people from all cultures and nations (Isaiah 11:10) * All Israelites will be returned to their homeland (Isaiah 11:12) * Death will be swallowed up forever (Isaiah 25:8) * There will be no more hunger or illness, and death will cease (Isaiah 25:8) * All of the dead will rise again (Isaiah 26:19) * The Jewish people will experience eternal joy and gladness (Isaiah 51:11) * He will be a messenger of peace (Isaiah 52:7) * Nations will end up recognizing the wrongs they did to Israel (Isaiah 52:13-53:5) * The peoples of the world will turn to the Jews for spiritual guidance (Zechariah 8:23) * The ruined cities of Israel will be restored (Ezekiel 16:55) * Weapons of war will be destroyed (Ezekiel 39:9) * The Temple will be rebuilt (Ezekiel 40) resuming many of the suspended mitzvot * He will then perfect the entire world to serve God together (Zephaniah 3:9) * Jews will know the Torah without Study (Jeremiah 31:33) * He will give you all the desires of your heart (Psalms 37:4) * He will take the barren land and make it abundant and fruitful (Isaiah 51:3, Amos 9:13-15, Ezekiel 36:29-30, Isaiah 11:6-9) In short- there is no comment in the Torah that the Mashiach has come.
