Answer:
Jesus as the savior
Explanation:
According to Judaism, there are specific events that have to occured to the world before the Savior come:
- Jewish people returned to their homeland
- The third Jewish temple should be built
- The arrival of Messianic Age. In this age all people will be living in peace without any conflict
- Knowledge of God is spread all over the world and all people know it.
Jewish people belief that none of this events occurred by the Time Jesus was born, so they reject him as the Savior.
