i think a lot of Jews also reject Jesus because of history…
so many terrible things have been done to Jews in the name of Christ, and Christianity, and getting over that can be very, very difficult for Jews.
many Jews state that because Jesus didn’t restore Israel and bring about peace and righteousness around the world, that He could not have been the Messiah. Christians as well as Messianic Jews would answer that Jesus refered often to His second coming, when these things would be accomplished (Daniel 7:13-14, Matthew 24:27-31, Acts 1:6-9).
many Jews simply don’t know enough about Jesus or the prophecies He fulfilled to believe in Him. they have never read a New Testament to be able to see the prophecies fulfilled in Jesus, and to study the evidence for themselves.
