The Jews did believe Christ was the Messiah. They are now called Christians. The others are just late to the party. They will come in time, think of it as wandering in the desert.
Just the truth.
Christianity is only understood by looking at Judaism through the lens of the New Testament.
Starting from the beginning and heeding the instruction of Torah - that the Torah is given to Jews, that God is not a man, to ask priests and teachers, to ask your fathers and not follow teachers your fathers didn’t know, etc, etc - makes it impossible for a Jew to get to Christianity.
Don't bet on it. Why is my religion in need of something from your religion? It's not. Your ridiculous self-centered statement is tantamount to me suggesting you take up Islam and accept Allah as your god. Or worship Thor. Or start sacrificing children to Baal.
Most Jews did NOT believe J.C. was the messiah, because he did not fulfill the messianic requirements put forth in the Torah. Stop inventing "facts" to support your pathetic statements.
No amount of argument from you or your messiah buddies here will be sufficient to deny what the Torah says, so save bandwidth, save time, and peddle your "facts" elsewhere.
