Nobody can even prove that Jesus is the true Messiah, so how you going to prove there were three more "messiahs" after Jesus? Anyway, just a simple search got me this...
The concept of the Messiah has its foundation in our Jewish Bible, the Tanach, which teaches that all of the following criteria must be fulfilled before any person can be acknowledged as the Messiah:
Reason #1 – The Messiah must be from the Tribe of Judah and a Descendant of King David AND King Solomon – Jesus did not qualify.
The Messiah must be a member of the tribe of Judah (Genesis 49:10) and a direct descendant of King David & King Solomon (2 Samuel
7:12-14; 1 Chronicles 22:9-10). Genealogy in the Bible is only passed down from father to son (Numbers 1:1-18).
There is no evidence that Jesus really had this pedigree, and the Christian Bible actually claims that he did not have a “birth-father” from the tribe of Judah descending from King David and King Solomon (Matt.
1:18-20).
Reason #2 – Ingathering of the Jewish Exiles – Jesus did not do this.
When the Messiah is reigning as King of Israel, the Jews will be ingathered from their exile and will return to Israel, their homeland (Deut. 30:3; Isaiah 11:11-12; Jeremiah 30:3, 32:37; Ezekiel 11:17, 36:24).
This has clearly not yet happened and we still await its fulfillment.
Reason #3– Rebuilding of the Holy Temple – Jesus failed to achieve this.
The Temple in Jerusalem will be rebuilt (Isaiah 2:2-3, 56:6-7, 60:7, 66:20; Ezekiel 37:26–27; Malachi 3:4; Zech. 14:20-21).
The Temple was still standing in Jesus’ day. It was destroyed 38 years after Jesus’ crucifixion and it has not yet been rebuilt.
Reason #4– Worldwide Reign of Peace – Jesus did not accomplish this.
There will be universal disarmament and worldwide peace with a complete end to war (Micah 4:1-4; Hoseah
2:20; Isaiah 2:1-4, 60:18).
Wars have increased dramatically in the world since the start of Christianity.
Reason #5 – Observance of the Torah Embraced by All Jews – Jesus didn’t bring this about.
The Messiah will reign as King at a time when all the Jewish people will observe G-d’s commandments (Ezekiel 37:24; Deut. 30:8,10; Jeremiah 31:32; Ezekiel 11:19-20, 36:26-27).
Jesus never ruled as King, nor have all Jews embraced the commandments of G-d’s Torah.
Reason #6 – Universal Knowledge of G-d – Jesus clearly failed here also.
The Messiah will rule at a time when all the people of the world will come to acknowledge and serve the one true G-d (Zechariah 3:9, 8:23,14:9,16; Isaiah 45:23, 66:23; Jeremiah 31:33; Ezekiel 38:23; Psalm 86:9; Zeph. 3:9).
This, as well, has not yet taken place and we await its fulfillment.
No matter how many unusual & miraculous things Jesus seems to accomplish in the New Testament, he doesn't fulfill even one of the 6 criteria by which the Nation of Israel can recognize him as the true Jewish Messiah.
After you have shown a convincing argument on how Jesus is the Messiah, then after that you'll have to do the same with the three messengers that came after Jesus. Yet, how many of these six things have been fulfilled... especially the reason four, the one about peace? If all you can do is give an alternative interpretation... like making it metaphorical and not literal, then how are Baha'is different than Christians? But then, the Baha'i alternative interpretation differs from the Christian one. So you've got to not only reject the Jewish interpretation but also the Christian interpretation and I wouldn't be surprised if you'd have to reject the Islamic interpretation also. So what do we got? A bunch of religions telling the Jews that they should believe in these others religions because their prophet says he is the True One.
