Hyper-dispensationialism at its finest. Just who is the Israel of the bible? Apostle Paul states it thusly, A person is not a Jew who is one only outwardly, nor is circumcision merely outward and physical. No, a person is a Jew who is one inwardly; and circumcision is circumcision of the heart, by the Spirit, not by the written code. Such a person’s praise is not from other people, but from God.[Romans 2:228,29] So the true Jews, the true Israelites, have had their hearts, and not foreskins, circumcised by the Spirit of God.
[Now, let's go to the beginning. God calls Abram our of the land of Ur of the Chaldeans. He then changes his name to Abraham, and told him he'd be the father of many nations, so this shows that not just Israel was going to be involved in those He called. We can read Is this blessedness only for the circumcised, or also for the uncircumcised?[Here we see both Jews and Gentiles included as the circumcision always referred to the Jews and the uncircumcision always referred to the Gentiles We have been saying that Abraham’s faith was credited to him as righteousness.Under what circumstances was it credited? Was it after he was circumcised, or before? It was not after, but before! And he received circumcision as a sign, a seal of the righteousness that he had by faith while he was still uncircumcised. So then, he is the father of all who believe but have not been circumcised, in order that righteousness might be credited to them. And he is then also the father of the circumcised who not only are circumcised but who also follow in the footsteps of the faith that our father Abraham had before he was circumcised.[Romans 4:9-12]
So, the true Israel of the bible are all the faithful of all time and not the nation Israel in the middle east.
