Some brethren apparently have a problem with what Apostle Paul taught about the Israel in part that God blinded, per Romans 11.
Paul taught the blindness away from The Gospel which God put upon his brethren the Jews, would not be removed until the "fulness of the Gentiles be come in". That blindness, Paul called "the spirit of slumber" (also the idea of 'a stupor' or 'lethargy' per the Greek).
Rom 11:7-11
7 What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were 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.
9 And David saith, "Let their table be made a snare, and a trap, and a stumbling block, and a recompence unto them:
10 Let their eyes be darkened, that they may not see, and bow down their back alway."
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.
KJV
Apostle Paul goes on to tell us, Christ's Church, that we are not to be wise in our own conceits, because God has not forgotten those Jews He blinded away from The Gospel of Jesus Christ. They are still His elect chosen according to Apostle Paul...
Rom 11:25-34
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.
That means, when that "fulness of the Gentiles be come in" happens, that is when God is going to remove their spiritual blindness away from The Gospel. Then they shall believe on our Lord Jesus Christ and be saved.
26 And 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:
27 For this is My covenant unto them, when I shall take away their sins."
Apostle Paul is pulling from the Old Testament prophets where God promised to save His chosen 'seed' of Israel. Those Scriptures are about God Himself doing that. Even in Isaiah 65 God said He in final will make Jerusalem a rejoicing and her people "a joy". Just like Lord Jesus divinely intervened with Saul on the road to Damascus, per Acts 9, and Paul was converted to Jesus, The Lord Jesus is able to convert these unbelieving Jews to Him on that day also. Those who think He can't do that in the future show they don't know the Power of The LORD. One who is a 'chosen' elect He already owned from the foundation of the world. And such are His elect chosen of the seed of Israel.
28 As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers' sakes.
29 For the gifts and calling of God are without repentance.
And there it is, what I just explained, that God's chosen elect He will not go back on His promises to them. That's what "the gifts and calling of God are without repentance" means.
Thus for this present world, the unbelieving Jews are enemies of The Gospel for 'our sakes'. How's that? Because of their rejecting Jesus, The Gospel would then be sent to us the Gentiles.
30 For as ye in times past have not believed God, yet have now obtained mercy through their unbelief:
31 Even so have these also now not believed, that through your mercy they also may obtain mercy.
32 For God hath concluded them all in unbelief, that He might have mercy upon all.
As in times past, when we Gentiles were without Christ Jesus and God's promises, we were not under His mercy. But now, through the unbelieving Jew's rejection of The Gospel, we Gentiles have obtained God's Mercy by Faith on Jesus Christ.
That 32nd verse suggests that God is going to eventually have mercy upon them too, the unbelieving Jews that He blinded. When? When that "fulness of the Gentiles be come in." That will be when our Lord Jesus Christ returns, and then their blindness will be removed, and they will hear The Gospel with eyes to see, and ears to hear, and believe.
¶ 33 O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are His judgments, and His ways past finding out!
34 For who hath known the mind of the Lord? or who hath been His counsellor?
KJV
Paul then points out how this mystery of the Jew's spiritual blindness being for the purpose of His Mercy eventually being upon all, is a matter of The LORD's Own Wisdom.
