There are many things to address here:
1, 1948 is not what you are saying. There is no 'restoration' that does not include the outpouring of the Spirit and the new covenant and even the outreach to Gentiles.
Prophecy has been my calling for nigh 40 years. There is a two step process, God revives Israel as a Nation, then later he revives them spiritually, the very passages we speak about says this.
Ez. 37:7 So I prophesied as I was commanded: and as I prophesied, there was a noise, and behold a shaking, and
the bones came together, bone to his bone. 8 And when I beheld, lo, t
he sinews and the flesh came up upon them, and the
skin covered them above:
but there was no breath in them(No Holy Spirit in them).
9 Then said he unto me,
Prophesy unto the wind, prophesy, son of man, and say to the wind, Thus saith the Lord God;
Come from the four winds, O breath, and breathe upon these slain, that they may live. 10 So I prophesied as he commanded me,
and the breath came into them, and they lived, and stood up upon their feet, an exceeding great army.
11
Then he said unto me, Son of man, these bones are the whole house of Israel: behold, they say, Our bones are dried, and our hope is lost: we are cut off for our parts. 12 Therefore prophesy and say unto them, Thus saith the Lord God; Behold, O my people,
I will open your graves, and cause you to come up out of your graves, and bring you into the land of Israel.
13 And
ye shall know that I am the Lord, when I have opened your graves, O my people, and brought you up out of your graves, 14
And shall put my spirit in you, and ye shall live, and I shall place you in your own land: then shall ye know that I the Lord have spoken it, and performed it, saith the Lord.
Think this through, there is no way God could ever get Israel o repent as a Nation from their unbelief, unless they are brought back in unbelief, then they repent as one nation. We see when they repent, its obvious.
Zech. 13:8 And it shall come to pass, that in all the land, saith the Lord,
two parts therein shall be cut off and die; but
the third shall be left therein. 9 And
I will bring the third part through the fire, and will refine them as silver is refined, and will try them as gold is tried:
they shall call on my name, and I will hear them: I will say, It is my people: and they shall say, The Lord is my God.
Then the very next verse shows when this all goes down.
Zech. 14:1 Behold, the day of the Lord cometh, and thy spoil shall be divided in the midst of thee. 2
For I will gather all nations against Jerusalem to battle; and the city shall be taken, and the houses rifled, and the women ravished; and half of the city shall go forth into captivity, and the residue of the people shall not be cut off from the city.
So, Israel does not repent unto just before the DOTL/God's Wrath. The Nation of Israel is restored unto the EXACT STATE they were in at the Diaspora, a Nation that is dead spiritually. Later, the 70th week of penance finally sees them repent and turn back unto God at the 1335 Blessing (Two-witnesses).
2, God did not want to use the Gentiles only. He asked Israel repeatedly to be missionaries to the world. Acts 13:47 is quote of Isaiah.
Well, that is a given, the Disciples were all Jews, but he forsook Israel as a Nation, not individual Jews. That is why Israel is blind IN PART only, as a nation, but not as individuals, all men have the right to come unto God by faith, but Israel as a nation could not do that after 70 AD because God dispersed them the whole world over. They can and will do that during the 70th week. Jesus said when he comes back Israel will welcome him back as their messiah in Matt. 23:39 saying Blessed is he that comes in the name of the Lord.
God chose for many varied reasons not to use Israel, if Israel had of not rejected Jesus God would have set up the Kingdom Age in 70ish AD, most do not understand that, but of course God foreknew they would nit accept him. Now, if you are trying to reach the whole world with the Gospel of Jesus who will the world be more likely to listen to? Gentiles of course, who have gotten saved and testify to their salvation. If Israel had of not been dispersed, eventually the leaders would have perverted the Gospel over time and brought it in under the Judaism umbrella. We can see this in Gal. 3, where Paul says oh foolish Galatians, who has bewitched you that starting out in the Spirit (Faith) you are now following the Flesh (Law). Then he goes on to show them how the Law can save no one, and how it was the Promise that was the original Covenant, the Law was only added 430 years later, and once the promised seed (Jesus) had come the Law was no longer needed. Then he says this and most everyone misinterprets wat Paul is saying. There is neither Jew nor Gentile, Male nor Female, Slave nor Freeman.
But he is not saying that all are one in Christ like many think, just the opposite, he is telling the Galatians to STOP trying to be Jewish like (keeping the laws) in order to try and work your way to heaven via the Laws, instead of via Faith Alone !! So, if all are one, why did he use the Male and Female analogy? Because there are of course still males and females, and there are also still Jews and Gentiles. Paul was telling the Galatians to stop trying to be Jews, we are all one in God by FAITH ALONE. That was Paul's point in Gal. 3.
So, I never stated God did not want to use Jews, but of course he was not going to use Israel, God states in Ez. 37 that until the very end times He sees Israel as Dead Men's Bones !! Not a nation. So, how could God use a nation when He says Israel are not a Nation? You are conflating the Nation of Israel with individual Jews who God can and has used for 2000 years as a "small part" of the church at all times.
3, 'Being saved' in Romans is not an Israeli restoration. The quote of Isaiah there is historical; this has come to pass. Check 'being saved' elsewhere in the letter.
Yes, Isaiah prophesied all Israel will be saved, NOT every Jew but Israel as a Nation is salvaged. So, Paul is quoting a Prophetic Utterance yet to be fulfilled, which will be fulfilled at the very end, as Zech. 13:8-9 shows us.
4, The thing that shows all the way back to the beginning is the outreach to the nations. It is in the main promise quoted by the apostles from the patriarch narrative; they never mention the land promise. 'In the Seed, all the nations of the world will be blessed.'
Yes, Israel births the Messiah through whom all nations will be blessed, but God still sees Israel as Dead Men's Bones from 70 AD until 1948. Ez. 37 says so.
5, People often think 'irrevocable' is the last word on all this. Yet the very next verses are saying that the mercy and binding of God are all complete already! So it is not a matter of waiting for something in the future.
Nothing is completed, more Gentiles and more Jews will be saved. The Gentile Church gets raptured, then Israel repents. The 7 Feasts show the timing, if one understand all of this. We are told the mercy shown unto Israel by the Church helps God to reach Israel.
Rom. 11:30 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(Church) mercy they also may obtain mercy. 32 For
God hath concluded them all in unbelief, that he
might have mercy upon all.
So, via our Mercy (in the end times, after Israel is revived as in 1948) Israel sees the Pre Trib Rapture and they see everything we spoke about is coming to pass, this helps revive their faith in God, thus they are an open window when the Two-witnesses show up.
At the same time, it is amazing how many people do not realize the finality of Acts 3:24, especially those who quote the forever land promise. It is a warning that if they don't follow the new MOses, they will be cut off from the people. There is also the finality of 2 Th 2. But people only think the land promise is forever, and to come back to after the NT says nothing about it.
I truly do not even come close to grasping your POV. Are you a Preterist? Come on surely not.
Anyway, God Bless my friend.
