Are Jews still Jews whether they accept Jesus as Messiah or not? Yes.
Are Gentiles Jews after they become “adopted” (i.e., “grafted in”) to God’s family by the Holy Spirit through Jesus as Savior? No.
Will we all be speaking Hebrew when we get to heaven? There is no reason to believe that according to Scripture.
These questions are not supposed to be difficult, but due to the rise of domestic ‘Hebrew Roots’ cults many American Christians are confused about the Jews. Here are some simple verses that should clear up the confusion.
Revelation 2:9 and Revelation 3:9 are referring to a sect of people claiming to be Jews who are NOT Jews, but rather the “synagogue of Satan.” This could be a reference, and I believe it is, to the cults on the rise, teaching Gentiles that they are Jewish when they are not, convincing pseudo-Christians against the veracity of the Bible and making them doubt the Trinity. These former church goers, turn their back on the church, believing the church is pagan, along with Christian holidays including Christmas and Easter/Resurrection Sunday. Kabbalah is incorporated in these teachings, and the pseudo “Christian Jews” turn away from a saving knowledge of God and are neither Christians or Jews.
Revelation 21:24—In heaven there will be “nations”, plural—not just people from Israel present. “Nations” will be represented.
Revelation 15:4—“all the nations will come and worship before Thee.”
Galatians 2:14-15—“if you, being a Jew, live like the Gentiles and not the Jews, how is it that you compel the Gentiles to live like the Jews? We are Jews by nature and not sinners from among the Gentiles.”—What we see here is a distinction between the Jew and the Gentile. (Some Christians have been persuaded to believe that by faith in Jesus they are now Jewish, through the New Covenant, but this is not found in Scripture. God makes a distinction from Gentiles and the physical lineage of Jews.)
A new covenant has come to the house of Israel. (Hebrews 8:8). God now dwells in a “temple not made with hands”, so there is a New Covenant offered through the Holy Spirit living inside God’s people. He now lives inside the human heart of a person who has been saved, because the Holy Spirit has come! (Romans 12:1). Jesus came first for the Jew and then the Gentile, so the New Covenant also extends to the Gentiles, due to the Jews’ rejection of Jesus. (Romans 10: 18-21)
ROMANS 11:25—28: There is a partial hardening of the Jews until the “fullness of the Gentiles”; “from the standpoint of the Gospel they are enemies for your sake, but from the standpoint of God’s choice, they are beloved for the sake of the fathers, for the gifts and calling of God are irrevocable.” Jews are still Jews whether they believe in Jesus or not! They are still considered God’s chosen, though they have rejected their Messiah as God has allowed a “partial hardening” for Israel. Christians are not called Jews here, and Jews are not called Gentiles!
Abraham was made a “father to many nations” (Romans 4:17). If we were all supposed to be Jews through our faith in God, God would have never made Abraham a father of “many nations”, and we would have all been grafted in to be considered Israelites. That is not God’s view. Saved Gentiles are still Gentiles, though we have been adopted through Christ into God’s family.
Mark 11:17—“…My house shall be called a house of prayer FOR ALL THE NATIONS.” Again, we see here that we are not all considered “Israel” in the New Covenant.
1 Corinthians 12:13: “for by one Spirit we were all baptized into one body, whether Jews OR GREEKS…” We see once again that God does not call us all Jews in the “one body” of believers!!!!!!!!! This is an excellent verse to show that Gentile Christians are not considered to be Jews.
Acts 14:1—“a great multitude believed BOTH OF JEWS AND OF GREEKS.” If God considers all Christians “Jewish”, why does the Bible continue to make the differentiation?
Cornelius was NOT considered a Jew. He was called “righteous and God fearing,” but he was “of the Italian cohort” and Acts 10 NEVER refers to him as “Jewish” just because of his faith in God! Acts 10:22 refers to him “well spoken of by the entire nation of the Jews.” It does not say, “The Jews called Cornelius a Jew!” or “Cornelius, the Italian Jew through faith was right at home among his people, the Jews.” The Bible again makes a distinction between a “righteous” Gentile “giving alms to the Jewish people” (v. 2) but never refers to Cornelius as Jewish.
Finally, Acts 2:10-11 describes the various languages being spoken at the Day of Pentecost. If we will all be speaking Hebrew in heaven, and if Hebrew is the official godly language of all time, why didn’t God just make them all speak Hebrew on the Day of Pentecost? Why did He not reveal to them that with the Holy Spirit now everyone is Jewish? He allowed them to speak in their own tongue, because He is a God of love for all nations and “every tongue” shall confess that Jesus Christ is Lord, not just the Hebrews. He is a Father to all of His own, Jew and Gentile, “for God so loved the WORLD that He sent His only Son that WHOSOEVER believes in Him shall not perish but have everlasting life.” John 3:16. There is no mention of Gentiles becoming Jewish, because the Jews are a distinct race from the Gentiles according to God’s word.
It is both quixotic and anti-Semitic for Christian Gentiles to call themselves “Jews” just because they are now God’s chosen people, too. Our Gentile forefathers worshiped idols, but now we can pray to the God of Abraham, Isaac and Jacob, too. Such a message is offensive to the most Orthodox Jews, just like Romans 11:27-28 warns. Nowhere does the Bible say that we, as Gentile believers, will REPLACE Israel in God’s eyes. Though most Orthodox Jews are enemies of Christians, belligerent against our claim of knowing the God of the Hebrews as our Father for Christ’s sake, we should not claim to have taken their place in God’s heart.
