I read an intersting article today about a Rabbi who wrote down the name he believed was of the Messiah, but it was to be sealed until one year after his death.  The name was revealed to be Yehoshua..  Jesus.  From the article it says you can indentify the Messiah become He will appear to Israel after Airel Sharon's death (who is still currently in a coma).  More can be found at:
