I'm not as thick as you think I am.... :-)
Say to them, ‘Thus says the Lord GOD, “Behold, I will take the sons of Israel from among the nations where they have gone, and I will gather them from every side and bring them into their own land; 22 and I will make them one nation in the land, on the mountains of Israel; and one king will be king for all of them; and they will no longer be two nations and no longer be divided into two kingdoms. 23 They will no longer defile themselves with their idols, or with their detestable things, or with any of their transgressions; but I will deliver them from all their [a]dwelling places in which they have sinned, and will cleanse them. And they will be My people, and I will be their God." (Ezekiel 37:21-23)
The verses you quote indeed refer to a physical nation that will be ruled over by Jesus Christ at his return. Physical Israelites will return to the holy land....a resurrected King David will be their king:
Eze 37:24 "David My servant shall be king over them, and they shall all have one shepherd; they shall also walk in My judgments and observe My statutes, and do them.
Eze 37:25 Then they shall dwell in the land that I have given to Jacob My servant, where your fathers dwelt; and they shall dwell there, they, their children, and their children's children, forever; and My servant David shall be their prince forever.
However prophecies made to the "sons of Israel" can also apply to those who have been grafted into Israel through Christ. I think though that in these verses it's referring to physical Israelites.
Where does God make the slightest inference that when He is talking about the literal, physical nation of Israel, and when making promises to the literal, physical nation of Israel, that that includes Gentiles? How did the promises God made to the Jews in the Old Testament, thousands of years before the Church was established, possibly apply to the Church? Where in Scripture do you get the idea that the promises made to Israel include the Church?
Where is your supporting Scripture? God's program through the Church didn't even begin until Acts (Matt 16:18; 1 Cor 12:13; Acts 1:5; 11:15-16) while His program through Israel began in Genesis 12. Where is the Scripture that supports your claim that the promises God made to Israel include the Church?
