And the Messiah has not come - to us His second coming. To Israel and the Jews the first appearance of their Messiah.
It was revealed to the Jewish people at the FIRST coming of Christ that Jesus is their Messiah. Therefore, when the Lord Jesus comes again, it will be His SECOND coming to ALL, BOTH Jews and Gentiles.
At the first coming of Christ, John the Baptist announced to the Jewish people that that Jesus is the Lord, Jehovah, prophesied by Isaiah:
John 1:22-23 ”“
Then they said to him, "Who are you, so that we may give an answer to those who sent us? What do you say about yourself?” He said, "I am a voice of one crying in the wilderness, ‘Make straight the way of the Lord,’ as Isaiah the prophet said.”
God the Father revealed to Peter that Jesus is the Christ, the Messiah:
Matt. 16:15-16 ”“
He said to them, "But who do you say that I am?” Simon Peter answered, "You are the Christ, the Son of the living God.” And Jesus said to him, "Blessed are you, Simon Barjona, because flesh and blood did not reveal this to you, but My Father who is in heaven.
And on the Day of Pentecost Peter declared to the Jewish people that Jesus is the Lord and Christ, their Messiah:
Acts 2:22,36
"Men of Israel, listen to these words: ……………… Therefore let all the house of Israel know for certain that God has made Him both Lord and Christ””this Jesus whom you crucified.”
Paul continually proved to the Jewish people from the scripture that Jesus is the Christ, the Messiah:
Acts 9:22 ””
But Saul kept increasing in strength and confounding the Jews who lived at Damascus by proving that this Jesus is the Christ.
Acts 17:2-3 ”“
And according to Paul’s custom, he went to them, and for three Sabbaths reasoned with them from the Scriptures, explaining and giving evidence that the Christ had to suffer and rise again from the dead, and saying, "This Jesus whom I am proclaiming to you is the Christ.”
Acts 18:5 ”“
But when Silas and Timothy came down from Macedonia, Paul began devoting himself completely to the word, solemnly testifying to the Jews that Jesus was the Christ.
Acts 18:28 ”“
for he powerfully refuted the Jews in public, demonstrating by the Scriptures that Jesus was the Christ.
Note:
Messiah comes from the Hebrew word mashiach and means "anointed one” or "chosen one.” The Greek equivalent is the word Christos or, in English, Christ. The name "Jesus Christ” is the same as "Jesus the Messiah.”
