Answer: The Messiah will not be a savior who comes to rescue individuals solely from sin. He will be the leading representative of the Jewish people in all respects and will fulfill his mission during his lifetime (no second advent is needed). It is he who will complete the ingathering of the Jewish exiles and who will bring about a world at peace where "the earth will be full of the knowledge of the Lord, as the waters cover the sea" (Isaiah 11:9). Obviously, he has not yet come.
