Christians believe the messiah, that is, the one foretold in the Hebrew Text who has come in the person of Jesus of Nazareth. Jews emphatically do not believe that Jesus is the messiah. If his own people did not believe he was the Messiah, also his hometown people of Nazareth, why should anyone else. He was definably not the Messiah of the Hebrews. And yet he claimed to be sent to be sent only to the lost sheep of Israel. (Gentiles need not apply)
But he answered and said, "I am not sent but to the lost sheep of the house of Israel."
