You just demonstrated everything I said in the first paragraph of my post. Two peoples of God.
There is but one people of God, the Jews. The Gentiles were God's enemies. If you don't start with the right foundation, then you are mishandling the Bible. And it is simply... a foundation. The Gentiles, the enemies of God, but who, by the kindness of God, were included in the salvation provided in Christ, while the Jews became enemies for the sake of the gospel [being extended to the Gentiles]. At the end, the Jews will cease being enemies, and will draw near to God again and be saved. This will be the remnant elect of Israel within the nation of Israel.
Ethnicity and land prioritized. Focus on (eyes/heart) on national/ ethnic Israel instead of Christ. Separating the OT from its place in the Covenant of Redemption and severing its purpose from the story of redemption that is our Bible.
You do this more than I do. I see consistency between the Old and New Testament, where you put the New Testament in front of the Old. Consider the consistency of the whole story of the Bible. It is like an epic novel. You basically have three main characters, two of which are groups. God, Israel/the Jews, and then Gentiles. The conflict of the story is sin and what that does to the relationship between God and the two other characters. The prologue to the story runs from Adam and Eve all the way up to Abraham. Or call it book one, with Abraham starting book two. Book two is about Israel's tumultuous relationship with Jehovah, her husband. Israel, a people chosen by God to be a part from the Gentiles, that is to be a holy nation... set apart. The end of the book ends with the rejection of the Messiah and Christ's death, the birth of the Jewish church, and AD 70. A cliffhanger. An intermission in the story of Israel/the Jews, as the Gentiles take the stage in book three. In book three, the chosen people of God are in exile and under punishment by God for their rejection. With this, the once enemies of God, the Gentiles, are drawn near to God through Christ. He extends welcome into the church along with the believing Jews. Meanwhile the nation of Israel continues to languish under, to take an idea from James I believe, the chastisement of God. As Paul said, God has not rejected Israel. Those whom God loves, He chastises.
As our story of redemption continues in book three, God has put the Jews aside under a partial blindness and hardening, while He is gathering in the Gentiles... "until the fulness of the Gentiles has come in". At that point, God will bring His chastisement of Israel to an end with the second coming of Christ, and the end of Gentile domination. The one's God saves of Israel are the 1/3rd remnant God speaks of in Zechariah. All the rest are dead/damned. At this time Israel sees the actual fulfillment of the covenants made, which are temporal. We call it the millennial kingdom, or messianic kingdom. It is the fulfillment of all the foreshadowing of the first book of the trilogy, the first part of the story. The church will be around as well (obviously), but the focus of this time is Abraham, Isaac, Jacob, and Israel. They will all be there.
Consider part of the Old Testament prophecies say that during this time, it will be almost unheard of for someone to die before the age of 100. Unheard of. Since people will still be mortal, you have the usual possibilities for dying (I'm sure if a building falls on your head, you will still die), and sin will still be around, though rare, and immediately punished. Families will turn in their children for sin. This is also where Satan gathers his army for THE final battle before we enter eternity. So the epilogue of book three is the millennial kingdom followed by the final war and entry into eternity with the NHNE.
Notice the progressive consistency from beginning to end.
