Within our contemporary society, and amongst normal and sensible people with Scriptural understanding, are two opposite extreme types of prejudicial humans who confront us in their encounters with and against us.
One type has a racist, idolatrous, and even blasphemous worship of Jews, Israel, jewishness, and whatever else is related to jewish tradition(s) or claims to be related to judaism.
The opposite type has a racist antisemitic hatred against Jews, insisting that the gentile church has replaced and forever will replace Jews, Israel, and Hebrews as God's chosen. This type adamently disregards the physical blood-descendancy of Jews from Isaac and Jacob on, not only pertaining to racial purity and distinctive-tribes identification but also capacity to become saved and especially function as church leaders over gentiles.
Both are obviously incorrect in their false ideas and in propagating their deviant indoctrination against all who oppose and would oppose them.
Pertaining to the first type mentioned above, we have historical precedence in the Bible recording God's call to Abram away from his former polytheism to Judaic monotheism, and Abraham's accomodating response to serve the Trinitarian singular LORD.
We also see Ruth the Moabitess gentile not only brought into the family of Jews but becoming an integral part of the family tree from who Christ Jesus was born into (Ruth 4:17-22). In Romans 2:25-29 Saint Paul (a great Jew by blood and lineage of the tribe of Benjamin according to Romans 11:1), informs us that those who faithfully! practice the Law are the ones who are the true Jews, and not of the synagogue of Satan Saint John (another great Jews by blood and lineage) referred to in Revelation 2:9 and 3:9. Paul also mentions that Abraham had God-incepted faith before he was circumcised, and thus was an heir by faith in God though Christ to be humanly manifested when He was birthed through the virgin Mary later on.
However, concerning the second type mentioned above, God did promise the Holy Land - the borders of which were geographically specified within the Pentateuch - to be the eternal inheritance of blood-descendant Hebrew Jews who get and maintain allegience with God through Christ. Some, as Paul reminds us, in Galatians, were unfaithful and lost their property rights, but other Jews repented (and are repending and will repent) and therefore retained (and are retaining and will retain) their territorial allotments. In Romans chapters 9 though 11, Paul makes a point of reminding us that he himself is of the Jewish tribe of Benjamin and so God has obviously not rejected blood descendants of Isaac and Jacob and that lineage, even though a hardening has temporarily come upon part of them (and who - if remain hardened - will be damned like accursed gentiles who similarly remain hardened as part of the wicked majority "on the broad and easy road to destruction"). "Jews are entrusted with the oracles of God" said Paul in Romans 3:2. "To the Jews first, then also to the Greek" states Romans 1:16, 2:9 and 2:10. Paul continues in Romans 9:4-8 in declaring that Jews are Israelites, and to them belong the sonship, glory, covenants, giving of the law, worship, promises, patriarchs, and of their race, according to the flesh, is the Christ." Jesus Himself told the Samaritan woman in John 4:22 that "salvation is of the Jews."
Note that even when Paul speaks of Hosea reaching out to people who are not of jewish descendancy in Romans 9:25-26, he ties in blood-descendancy promise of salvation with Isaac and Jacob in Romans 9:7-13 instead of Ishmael and Esau.
Speaking of arabs and their ancient child-of-the-flesh-and-not-promise forefather Ishmael and his slave-mother Hagar, Paul the Jew by inference associates them with no-promised-inheritance-to-them exclusion-resultant faithlessness and disobedience, according to Galatians 4:22-31.....again relating that to futile and imperfect human-effort attempts at trying to please God merely though hit-and-miss obedience and disobedience to law without faith in Christ Jesus as Redeemer/Savior and Lord.
At the heart of this matter is the tension between obeying the law and simply accepting the Lord as Lord by faith. Some people have always had trouble reconciling law with gospel, and wrongly placing gospel over law to the abolition against law, misbelieving that the law is now a worthless death-causing thing to be replaced by a live-like-the-devil irresponsibility of misused grace and forgiveness in a workless dead faith Saint James despised in James 2:24 where he reminded us that "a man is JUSTIFIED (saved) by [good] works and not faith alone"....which balances out the faith-alone apparent-one-sidedness of Romans 3:20-26 and Romans 9:32.
