Who is "National Israel"? I've seen this term used in these boards as though "National Israel" refers to the genetic descendants of Abraham only, ie "the Jews" only.
Deuteronomy 14:2 says,
"For you are a holy people to the LORD your God, and the LORD has chosen you to be a peculiar people to Himself, above all the nations that are on the earth."
It was talking to all 12 tribes of Israel. It was spoken long after Jacob (Israel) when on his death-bed, told his son Joseph the following regarding Joseph's son, Ephraim:
"And Joseph's father, Jacob, refused and said, I know, my son, I know. Manasseh also shall become a people, and he also shall be great, but truly his younger brother Ephraim shall be greater than he is, and his seed shall become (Hebrew: melo goy: "the fullness of the Gentiles", translated correctly into English as "a multitude of nations.") (Gen 48:19).
Deuteronomy 14:2 was spoken long before Israel was split into a Northern kingdom (the house of Israel) consisting of 10 tribes, and a Southern kingdom (the house of Judah) consisting of Judah (the Jews) and Benjamin. It was long before God, through the prophets, began collectively calling the 10 tribes of the Northern kingdom "Ephraim".
Deuteronomy 14:2 was spoken long before God told Hosea to prophesy regarding the house of Israel,
"For you are not My people, and I will not be your God. Yet the number of the sons of Israel shall be as the sand of the sea, which cannot be measured nor numbered. And it shall be, in the place where it was said to them, You are not My people, there it shall be said to them, You are the sons of the living God.
Then the sons of Judah and the sons of Israel shall be gathered together, and shall set over themselves one head, and they shall come up out of the land. For great shall be the day of Jezreel." (Hosea 1:9-11).
Deuteronomy 14:2 was spoken long before the 10 Northern tribes were exiled from their land and scattered among the nations, long before the descendants of the 10 Northern tribes intermarried with Gentiles in the nations to which they were scattered, to the point where the original 10 tribes are untraceable today.
Deuteronomy 14:2 was spoken long before Jeremiah prophesied that God would cut a new covenant with the house of Israel and the house of Judah that would not be like the covenant He cut with them during the days of Moses (Jeremiah 31:31).
Deuteronomy 14:2 was spoken long before the apostle Paul took the above prophecy mentioned in Hosea, which refers to the house of Israel and not to the Jews, and applied it to Gentiles who believe in Jesus":
"What if God, willing to show His wrath and to make His power known, endured with much long-suffering the vessels of wrath fitted to destruction; and that He might make known the riches of His glory on the vessels of mercy which He had before prepared to glory; whom He also called, not only us, of Jews, but also of the Gentiles?
As He also says in Hosea, "I will call those not My people, My people; and those not beloved, Beloved." And it shall be, in the place where it was said to them. "You are not My people"; there they shall be called sons of the living God." (Romans 9:22-26).
Deuteronomy 14:2 was spoken to the 12 tribes of Israel long before the time which we read of in the gospels, when the chief priests and pharisees heard Jesus' parable of the wicked vinedressers (at the time the Lord told them that the kingdom would be taken from them), when the chief priests and the pharisees, hearing the Lord's parable, "understood that Jesus spoke of them" (Matthew 21:45).
We must remember that the chief priests and pharisees were the vinedressers in the parable (Matthew 21:33-45). The Lord could not have been speaking of all the Jews - because not only were the apostles all Jews, but the apostle who was given the keys to the kingdom of heaven, was a Jew (Peter). (Matthew 16:19).
Matthew 21:33-45 makes it abundantly clear that Jesus was addressing the chief priests and pharisees when he said the kingdom would be taken from them, and the chief priests and pharisees understood by the parable of the wicked vinedressers that Jesus spoke of them.
So there has always been only one nation called Israel, the Gentiles who beieve in Jesus are part of it, and God considers them "the house of Israel", whereas the Jews who believe in Jesus are "the house of Judah".
The prophecy in Hosea refers to the house of Israel, NOT to the Jews.
THERE HAS THEREFORE ALWAYS BEEN ONLY ONE NATION BUT THERE IS A NEW TEMPLE, WHICH IS ALSO THE CHURCH
