I see no scriptural support for anything you wrote. What did Paul write about the true Israel of God?
You may not have spent enough time in the Scriptures? What I said, whether you agree or not, should be understood as based on one view of Scriptures, if you are a veteran Bible student.
1st, Paul indicated that the promises of God are eternal, and not subject to time and covenant. Do you understand where I get that from?
2nd, whatever Paul says about who is acting like a true Israelite, he is not re-defining the term "Israel." The Scriptures do not teach re-definition. Rather, they teach authentic practice as Israel was called to practice God's Law.
Paul taught in Romans 9-11 that even in the NT era, when Israel as a nation has failed, a remnant remains until Christ returns to save "all Israel." Contrary to the opinion of some, "all Israel" is referring to an "entire nation," and not to the rebirth of every individual of the Israeli state.
Many times in the OT era Israel's practice under the Law, faithfully and nationally, brought them *political salvation* to preserve the promise of a nation representing the true God. This "political salvation" is what Paul is talking about, and is clearly understood from the pronouncements of the "blessings" on Mt. Gerazim in the OT Scriptures.
To the Ephesians he wrote of God's breaking down the "middle wall of partition" between Jew and Gentile and made of the two ONE NEW MAN.
Yes, and this opening of the barrier between Israel and other nations, with respect to a covenant relationship with God, has nothing to do with re-defining "Israel." Israel was brought into covenant relationship with God while they still had lots of problems in their membership or citizenry. And God has now opened the door for many other nations, with all of their "warts and pimples."
God is looking for nations to carry the message of His grace. He only started with Israel because He had to start somewhere, and chose to start with a faithful man of God, namely Abraham. Israel fell in history a number of times, and many Christian nations have fallen, as well. None of this means that God only chose remnants, and did not choose nations to represent the entire social package as He wished Christianity to affect it.
In Galatians 6, he addresses the issue of the Jews who were demanding that Gentiles be circumcised, while they themselves did not even keep the law but boasated in their standing as the "circumcised." Paul, himself a "Hebrew of Hebrews" who boasted in his circumcision and Jewish heritage (Phil. 3:4-6) expressed the need to be boasters in "the cross of our Lord Jesus Christ." It was not the circumcision of the OT nation of Israel nor the uncircumcision of the Gentiles that counted for anything. What matters is a "new creation." To the saints at Rome, Paul wrote that one was a Jew INWARDLY and not OUTWARDLY. One is a Jew who is circumcised in his heart (Rom. 2).
Yes, Paul is speaking about Israel's failure to enter into the new covenant of Christ and leave the old Law of Moses behind, which had been focused on bringing them into the New Covenant. We are not to enter into "Religion," but rather, into Christ. Israel had known God, and not just "Religion." But over time, the revelation fails, as it does in all nations. Israel was just the 1st to fail, and by no means indicates they will stay "fallen." They can be recovered when the time is right.
The writer of Hebrews compared the old with the new, stating that the old ("first") covenant with the nation of Israel was not perfect. If it had been, the author states, "there would have been no occasion to look for a second" (Heb. 8:7).
The temporal nature of the Old Covenant does not mean it was meaningless and worthless! Following that Law Israel did right, was spiritual, and followed God's righteousness. Backsliding in the nation does not mean the system was flawed!
He goes on to establish the timing of the end of that old covenant with the physical nation of Israel--in the writer's own day the covenant was "growing old, becoming obsolete, and READY to pass away" (vs. 13). The old and everything associated with the nation of Israel was abolished when everything pertaining to it was destroyed in A. D. 70 (i.e., the Temple and Jerusalem).
Well yes, Israel failed in the time of Jesus' earthly ministry. And it took a full generation for the Temple to fall--perhaps 40 years? None of this means Israel cannot rise again, which is what I think the Prophets foretold. God's promises cannot fail. It will happen, I think.
National Israel was no more and was to be no more.
God made eternal promises to Abraham on behalf of his national posterity. They are "eternal." Israel's failure in the NT era will not stop them from regrouping when Christ returns. And in a sense that process has already begun with the restoration of the Israeli nation in the Middle East.
