Pardon me if I am misreading you comment here, I have not paid attention to your view up till now, but I sense you don’t believe that Israel (Jews) are still Gods chosen people and will once again be dealt with on an individual (as a nation) basis during the Tribulation period.
Romans 11 specifically deals with that and explicitly says that the Jews, ie Israel, will be again dealt with as it says “until the fullness of the Gentiles be come in.” Once God determines that the end of the time for the Gentiles has come He will again, for a period of seven years, deal with the Jews as a nation.
Those Jews who follow Christ are still Gods chosen people. Those who once again become faithful, like the Old Testament remnant, will rejoin Gods chosen people. Those who reject Christ are "broken off" from the tree. This is the clear teaching of Romans 11. Is it not?
How could Catholicism, Eastern Orthodoxy, and all Protestant denominations prior to John Darby got this simple teaching wrong?
