You are funny. Jews are not a race or a nation. Jews are a religious group a subset of the house of Israel further divided into Pharisees and Sadducees. Non-Jews are not Jews. The scripture existed before the Jews. Simon the Canaanite was not a Jew. Was Simon the Canaanite excluded? What the Jews hear as a warning the world hears as hope.
Paul answers your question in Rom 11
7 What then? Israel hath not obtained that which he seeketh for;
but the election hath obtained it, and the rest were blinded.
Only the election obtained it, the rest are blinded
8 (According as it is written, God hath given them the spirit of slumber, eyes that they should not see, and ears that they should not hear
unto this day.
That includes you
9 And David saith, Let their table be made a snare, and a trap, and a stumblingblock, and a recompence unto them:
10 Let their eyes be darkened, that they may not see, and bow down their back alway.
David is peaking about you and all of Isreal.
11 I say then, Have they stumbled that they should fall? God forbid: but rather through their fall salvation is come unto the Gentiles, for to provoke them to jealousy.
Paul says the fall of Israel brought salvation to the Gentiles. Therefore Gentiles are not Israelites.
12 Now if the fall of them be the riches of the world, and the diminishing of them the riches of the Gentiles; how much more their fulness?
Notice the fall of Israel is the riches of the world. and their diminishing the riches of the Gentiles...
13 For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, I magnify mine office:
Paul is speaking to Gentiles here not Israelites.
14 If by any means I may provoke to emulation them which are my flesh, and might save some of them.
He wants to provoke Israelites(his flesh) to follow his teachings that they might be saved
15 For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead?
He says they are cast away so that the world might be reconciled to God
16 For if the firstfruit be holy, the lump is also holy: and if the root be holy, so are the branches.
He is indicating that all can be holy
17 And if some of the branches be broken off, and thou, being a wild olive tree, wert grafted in among them, and with them partakest of the root and fatness of the olive tree;
He is showing gentiles the wild olive are grafted with Israel to form the Church.
18 Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee.
19 Thou wilt say then, The branches were broken off, that I might be grafted in.
Gentiles are warned not to boast against Israel
20 Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear:
21 For if God spared not the natural branches, take heed lest he also spare not thee.
22 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.
Israel was broken off because of unbelief and gentiles were grafted in because of belief
23 And they also, if they abide not still in unbelief, shall be grafted in: for God is able to graft them in again.
God is able to graft in Israelites who believe.
24 For if thou wert cut out of the olive tree which is wild by nature, and wert grafted contrary to nature into a good olive tree: how much more shall these, which be the natural branches, be grafted into their own olive tree?
Gentiles were cut off from Israel but are now given the opportunity to be grafted in so Paul is saying the same way God is able to graft in an Israelite who believes.
25 For 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.
Notice Israel is blinded until the fulness of the Gentiles be come in, that mean until the gospel is preached throughout the world.
So I don't agree with you, my friend. I agree with Paul.
