I'm Jewish. Prove to me your Jesus is the Messiah and I will become a Christian.
Isaiah 7:14 is wrongly translated by Christian Bibles. This was due to a mistake by the translators of the Septuagint who wrongly translated the Hebrew "almah" as virgin into Greek when actually the word almah simply means a young woman, not a virgin. Also, read the context of this verse, it's clearly about King Hezekiah not the Messiah.
The servant in Isaiah 53 in not the Messiah it's Israel. Read the context of the chapter.
The criteria for the Messiah:
Jesus was not born of the house of David. Joseph was not his biological father even according to your own scriptures. Therefore he was not the house of David. It is not possible to be adopted into the house of David either, it must be 100% biological. There is no proof Mary was from the house of David. In fact, even if Joseph was his biological father, there is no proof he was from the descended from David either since the New Testament gives contradicting genealogies for Joseph.
Jesus did not restore Israel but instead got himself crucified.
The world has been exactly the same since the time of Jesus. It is in no way like the prophesied Messianic age.
Jesus did not build the Third Temple. He was crucified instead.
In fact Christians are taught to abhor the Law given to Moses at Sinai and do not follow it at all in accordance with the teachings of Paul. Jesus actually did follow the Law but clearly since Paul corrupted his message and did the complete opposite of Jeremiah 31:33 Jesus did not fulfill this prophecy and thus Jesus cannot be the Messiah.
Christians in fact worship Jesus and the Holy Spirit alongside God. This is not monotheism. The Tanakh nowhere says the Messiah will God and this is a later Christian concept invented when it mixed with Greek philosophy.
Welp Christians, it looks like Jesus isn't the Messiah after all and your religion is a gentile corruption of Judaism. That Jesus rose from the dead and is going to come back to fulfill the prophecies has got to be one of the worst cop outs ever and is nowhere in the Hebrew Bible.
You don't have to convert to Judaism but perhaps become a Noahide. This would suit you best. Unless you have some master proof, please offer it up to me.
Right now, offer it up. I challenge you to prove to me from the Hebrew Bible that Jesus is the Messiah. Do this and I will convert to Christianity in a heart beat.
