I wonder what you have to say about Abraham. Jesus and the apostles thought highly of his faith, and I find he mightily influenced Christianity.
I have met people dressed like a Jew, strongly affirming they are Jewish, but don't convince anyone they ever knew God. Jewishness for them is just a peculiar way of life. History is full of those who defamed true Jews who loved God with all their might. Some Christians these days shame the Church, though claiming they are dedicated believers. Many demonstrate they have yet to know Jesus personally.
When Jesus comes back here, He will have some startling changes to make in restored Israel, Jerusalem to be capitol of the world, in religion, commerce, medicine, sheer might, under rule of Jesus the Christ, according to Zechariah 8, partially fulfilled, broken up with destruction of Jerusalem, to be resumed in the last days. God stopped the feasts and ordinances when Israel rejected Him, but has made it clear He will restore Israel to it's former glory, while the Church, including both Jews and gentiles, thrives and will populate the New Jerusalem together.
Rev 3:9 concerns the Church (at Philadelphia) and mentions those who pose as Jews will end up worshiping at their feet. That in no way condemned all Jews, of which Jesus was one all His life. The problem in Jesus' day, and during the next few centuries, were Judaizers, chiefly corrupt scribes and Pharisees. Understand that Pharisees were always known to be corrupters of Judaism, and were not official arms of Judaism. They were more of a political party, a movement of ideas, who added rules and regulations onto Judaism, which Jesus resisted.
The earliest Church population was Jewish for about the first 7 years until Cornelius was saved, birthing the Gentile Church movement. That should at least suggest all of Judaism were not of the household of Satan. They remained Jews, and were Christian too, nedding to be discipled like us all. When the Jews took the gospel to the Gentiles, that didn't stop the Christian Jews from preaching Christ. Most of the New Testament was written by Jews who knew Jesus. It's interesting that even now some "Christian" movements claim they are the true Jews, including "Replacement Theology" adherents, claiming they are the new Israel and stand to inherit the ancient blessings. It is all lies. They will worship properly some fine day.
The 144,000 virgins of Rev 7, 12,000 of each tribe of Israel, who do you say they will be? Some Gentiles falsely claim to be of each of those tribes by personal revelation by angels. It won't be God changing the religion of the Pentateuch, or renaming the descendants who longed for the Messiah to come in His glory. Yes, they missed Jesus, and have paid a huge, tragic price for that through the centuries. But the remnant will be there as prophesied. They will celebrate their feasts in view of Jesus on the throne among them, along with the redeemed Church coming with Him.
