That isn't what is being done. Rather you should take the verse you've presented and consider what the apostle says about the Jews, and Israel in Romans 11. They are not incompatible, its all addressed in Romans 11. "All Israel shall be saved."
Which all Israel, inward jews born agin of the Spirt of Chrsit or outward in respect to thier corrutped flesh .This is seeing if any person has not the Spirt of Chrsit they simply do not belong to Him
Rom 9:6 Not as though the word of God hath taken none effect. For they are not all Israel, which
are of Israel:
All Israel are not Israel as the bride of Christ or born again Jews. Jews in respect to the inward, born again of the Spirit of Christ, and not outward in respect to their corrupted flesh. We simply do not know Christ, the anointing Holy Spirit of God after any rudiment of this world. Even Christ of his own self clearly said his flesh does not profit as if it was Spirit.
Why in the world would a person desire glory in the flesh of any man is a puzzle?
All Israel is not the Israel as the bride of Christ is Israel as born again Jews. Those Jews in respect to the inward born of the Spirit of Christ not outward in respect to their corrupted flesh. We simply do not know Christ the anointing Holy Spirit of God after any rudiment of this world. Even Christ of his own self said his flesh does not profit as if it were Spirit. Why in the world a person desire in the glory in flesh of any man is a puzzle.
God is eternal Spirit, not a man as us
Christian is the new name “God named” his born again people, previously call Jews or Israel.
Romans 2:28 For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh:
Below a inward Jew is rebuking one that is outward of the flesh and not inward of the Holy Spirit.
Rev 2:9 I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy
of them which
say they are Jews,
and are not, but are the synagogue of Satan.
