To, your point concerning the Jewish and Gentile believers being kept separate. There would seem a more simple answer to your question concerning these. The saved all belong to the Bride, both Jew and Gentile. They are the resurrected bride who will reign with Christ from the promised land and over the earth for 1000 years; so then, following the first resurrection. The unsaved who may have taken the mark, but who did not worship the beast will appear as the sheep at the sheep and goats judgment of nations. This after Jesus returns. They then will inhabit the nations to be ruled over. They are not saved as such, because they know nothing of the Lord or of His brethren, whom they are told that they have helped. They had no knowledge of giving Jesus or His brethren something to eat or drink when they were hungry or thirsty. But the earth following this age was prepared for them. It is these Gentiles who will bring back the also still unsaved Jews from among these gentile nations to inhabit the land promised to them under the land covenant. Messiah and His bride will reign over them. These unsaved nations will come up year after year to offer sacrifice in the Temple of God. This fact proves that they were not saved, because were they saved then there can be no needed sacrifice.
Jews who are saved out of Petra in Edom will be in the bride of Christ. They are to be represented in (returned to) the Olive Tree once the last Gentile who is to be saved is finally saved. This world is closing in on these times.
The good Doctor answered me on his blog; and this is my thinking as to that answer. He has disregarded hiss on plea for plain speaking. What I have stated here perfectly aligns with the Scriptures in very plain language. His answer: not so.
The fact is that every believer who accepts Messiah before His return, will reign with Him in His millennial kingdom this is the plainly stated language of the Scripture. (See Rev 20, Matt. 25; Eph. 2-4; Romans 11; Zach. 12-14). This is God’s plain word concerning what is to come.
