Knock knock, Christ was Jewish. Hashem is their God. Practising Jews of faith who follow the Torah are saved. They don’t need Christianity.
Right now the Jews in Israel make a mockery of God's law, a recent example being how the Orthodox Jews temporarily sell their land to Gentiles to work them, because God no longer gives them an abundance during the 6th year so that they can let the land rest on the 7th. The Jews have no Priesthood. Their sacrifices are no good to them. Gentiles stomp all over the Temple Mount. The Temple has been destroyed for almost 2000 years, destroyed on the anniversary of God's judgment for their sins when He destroyed their last temple. There is no Prophet. There is no law giver from the house of Judah. There is only silence.
Israel is nothing more than a secular state where even the Orthodox do not follow the Old Testament, but instead render the law void through their interpretations so that they do not fall under the curse of the law:
Deu 27:26 Cursed be he that confirmeth not all the words of this law to do them. And all the people shall say, Amen.
