He is talking about 2 types of spiritual animal in the overall nation of Israel. He is teaching that the blinding of the majority was not wholesale and did not prevent future Jews coming through. There was/is a remnant that have eyes to see and ears to hear.
So much for us not talking about this topic anymore! Haha. But we can do so respectfully and maybe just one last time.
I believe that you're missing the context. Let's take a closer look at the text.
Romans 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 stumblingblock, and a recompence unto them: 10
Let their eyes be darkened, that they may not see, and bow down their back alway. 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. 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? 13 For I speak to you Gentiles,
inasmuch as I am the apostle of the Gentiles, I magnify mine office: 14 If by any means I may provoke to emulation them which are my flesh, and might save some of them.
So, in verse 7, Paul initially points out that the election (remnant) "hath obtained" that "which he seeketh for", and the rest were blinded. After that his focus remains on "the rest that were blinded" in verses 8-10 since they are the ones with "the spirit of slumber" and darkened spiritual eyes. Agree?
Well, in my view, Paul continued to talk specifically about the rest who were blinded in verse 11 and he asked if thy stumbled to the point that they would fall and he said "God forbid". Surely, he wasn't asking if the remnant had stumbled. He was asking that about the ones whose table was made "a stumblingblock", which were those who were blinded. So, those who were blinded and whose table was made a stumblingblock did not stumble to the point of falling. Calvinism says they fell and were made reprobate, but Paul says they stumbled and did not fall.
So, in my view, Paul was saying God forbid that they had fallen and were reprobate. No, they were blinded only temporarily for the purpose of bringing the gospel to the Gentiles to make them jealous. Paul wished to take advantage of their jealously to make them too want to be saved like the Gentiles were, and that's what he was saying in verses 13 and 14.
Later Paul said this about those Israelites who were blinded and cut off in his day.
Romans 11:23 And they also, if they abide not still in unbelief, shall be grafted in: for God is able to graft them in again.
Paul did not give up on those who were blinded and cut off because of their unbelief. He hoped to lead some of them to "abide not still in unbelief" so that they could be saved.
Edit: My letter "e" key on my keyboard is not working well, so if I have any typos missing the letter "e", that's why.
