You're missing a major part of the 'mystery'......The church age. There is neither Jew nor gentile. Anybody who has faith alone in Christ alone in the church age is a new creation, His body, His Bride, His royal family. When the fullness of the Gentiles/His Bride is complete.......He will deal with national Israel. The tribulation.
Another part of the 'mystery?' Romans 11. I will start it for you.....
1I say then, Hath God cast away his people? God forbid. For I also am an Israelite, of the seed of Abraham, of the tribe of Benjamin. 2God hath not cast away his people which he foreknew.
23And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again. 24For if thou wert cut out of the olive tree which is wild by nature, and wert graffed contrary to nature into a good olive tree: how much more shall these, which be the natural branches, be graffed into their own olive tree? 25For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in. 26And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob: 27For this is my covenant unto them, when I shall take away their sins. 28As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers' sakes. 29For the gifts and calling of God are without repentance.

I don’t think you ever heard what I’m saying or rather what Paul’s saying israel and the gentiles are one group now any israelite who repents and accepts the gospel or any gentile who repents and accepts the gospel that’s the only salvation for anyone Jew or gentile there is no difference all have proven to be sinners
The gospel is what israel was promised would save them if they repent and accept the gospel they also can inherit the kingdom just as any gentile can inherit the kingdom
Jew and gentile are the same to God flesh and blood doesn’t mean a thing anymore
What you’ve quoted there that Paul’s saying is perfectly in line with ot prophecy but doesn’t really fit with what I’m saying or change this part
“Wherefore remember, that ye being in time past Gentiles in the flesh, who are called Uncircumcision by that which is called the Circumcision in the flesh made by hands; that at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world: but now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ.
For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us; having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace; and that he might reconcile both unto God in one body by the cross, having slain the enmity thereby: and came and preached peace to you which were afar off, and to them that were nigh.
For through him we both have access by one Spirit unto the Father. Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God; and are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone; in whom all the building fitly framed together groweth unto an holy temple in the Lord: in whom ye also are builded together for an habitation of God through the Spirit.”
Ephesians 2:11-22 KJV
That’s all I’m getting at pretty straightforward quoting from Roman’s doesn’t address what Paul’s saying there at all
“which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit; that the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel:”
Ephesians 3:5-6 KJV
That’s all saying friend this that you quoted
“Well; because of unbelief they were broken off, ( they rejected Jesus and the fospel )and thou standest by faith.
Be not highminded, but fear: for if God spared not the natural branches, take heed lest he also spare not thee. ( if he cut them off he will cut you off also if e persist in unbekief)?
Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness, if thou continue in his goodness: otherwise thou also shalt be cut off.
And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again.”
Romans 11:20-23 KJV
If israel repents and accepts the gospel indeed they are included with the f titles and any other israelite who had believed the gospel
a ot really sure how you’ve connected the two
