1): God no longer makes plans with anyone based upon their ethnicity since the New Covenant began. This would include " jews" as well because we are all made in the image of God and they fall into that category. You've heard it many times before in scripture. There is no difference between the Jew and the Greek.
2): Any promises of a literal land inheritance were fulfilled. In several places, especially in
Joshua 21:45:
There failed not ought of any good thing which the LORD had spoken unto the house of Israel; all came to pass.
2a): Throughout the OT, the future promise of an eternal land inheritance (which is worded in many cases in allegorical form ) is for all who partake in the body of Christ. Not in a future unbiblical "literal millennial reign", but at the end of this current earth age.
3): There is only one everlasting Covenant, and that would be through Christ's blood. In the Old testament we read of the heart being circumcised instead of the foreskin. This is New Covenant language.
4): as a born-again Christian, I don't bow down or put myself in second place to unrepentant jews, as is the indoctrination of our day through the misinterpretation of scripture. In other words, when you do a deep dive, when you really want to know the truth about what Israel really means in God's sight, you will find out that it is Christ and His people. There never was a replacement, just a fulfillment that you have to follow out by studying scripture. And yes, this would include some Jews as well, who forsake their demonic religion (I say it like it is).
I would suggest you were on the right track 25 years ago. I will offer some theological and eschatological counterpoints for your consideration. Unfortunately, I really don’t really have time keep going back and forth at the moment.
1. The inclusion of Gentiles in the New Covenant does not, by itself, nullify God’s promises to ethnic Israel or rule out a future purpose for the Jewish people. Furthermore, there are multiple promises concerning Israel, and they have not all been fulfilled in their entirety. Israel, for instance, has never possessed or occupied the entirety of the Promised Land as defined by Gen 15:18-21.
2. If “neither Jew nor Greek” means God no longer has any distinct purpose for ethnic Israel, would “neither male nor female” mean God no longer recognizes the distinction between men and women? Obviously not. Equality in one respect does not erase every distinction in every other respect. Therefore, Gal 3:28 cannot simply be used to dismiss every one of God’s specific promises for Israel.
3. God chose Abraham among the nations and made an "everlasting" covenant with him and his descendants (Gen 17:7-8). There wasn’t just one covenant but multiple covenants. Some of the covenants were unconditional while others were conditional and came with blessings and curses for disobedience. But disobedience didn't forever nullify those promises. There is a repeated pattern of God calling for repentance and promising forgiveness if they do (Zec 1:3). God has always desired redemption and reconciliation. That is the central theme of the Book of Hosea. It's also what Scriptures indicate will happen.
4. Romans 11 confirms that God is not done with His people. Paul identifies his people as ethnic Israel, making a distinction between Israel and the Gentile church throughout his discourse. Israel is representative of the olive tree, and the Gentiles are the branches. We can infer this because Paul would have used imagery his audience was already familiar with. Jeremiah 11:16 had previously associated the olive tree with Israel. Additionally, Isaiah 5:1–7, Psalm 80, and 4 Ezra associate Israel with the vine/vineyard. God declared that if Israel turned from their unbelief, He has the power to graft them back into the tree. This demonstrates that being broken off because of unbelief does not necessarily mean permanent exclusion. Just as God grafted Gentile believers into the tree, He is able to graft Israel's natural branches back in. Romans 11 concludes by declaring God, in His mercy, will take away their sins, and "all Israel will be saved."
5): I never said that Islam was not a threat to this world. Governments can easily stop this Islamic infiltration. The problem is our governments are infiltrated by "God's chosen people" who have the influence in policies that allow mass migration to begin with. In other words, they are using the Islamic world as a tool for our destruction. I know you're going to freak when you see that, but keep doing your research is what I say respectfully.
Those government leaders you speak of are globalists who don’t identify with any nation, creed, or ethnicity. Most of them are non-Jewish. The ones that are Jewish are Jewish in name only. They are secular Jews who have abandoned traditional Jewish religion and communal life. The fact is, even if such a conspiracy were true, it could never be accomplished without non-Jews. Yet, all these conspiracy theories blame Jews for literally everything. But this is nothing new. There have been Jewish conspiracy theories for thousands of years. Where do you think this leads to? History shows it leads to actual genocides and pogroms.
The question is, why do Jews have more conspiracy theories associated with them than any other people? Why has a tiny ethnic minority (the Jews) have been the most persecuted people in history? Why does a tiny country (Israel) attracts such extraordinary attention relative to its size? That is the real Jewish question. Hint: it’s spiritual. Say what you will about dispensationalism, but it is the only view that explains the why. At its core, this has always been a spiritual battle.
