Paul separated Israel and gentile in romans 11. It did not matter if they believed or not. He did not say believing gentile and Isreal were the same, He said non believing (blinded) and believing Israel were children of the promise, hated according to the gospel (for those blinded) but beloved because of the promise. How can it be just believing gentile and jew if they are hated for the gospel?
That part, when taken with everything else paul said, proved my point.
