In post six did you not say that that scripture was meant for the Israel of those days and not modern times? That is the way I read it.
I think at all times, those verses have referred to "the Israel of God", i.e., Believing Jews and also those gentiles who are incorporated into this Believing-Jewish community.
It's not my wife's Conversos/Sephardic Jewish (i.e., Spanish-Jewish, on her mother's side, by way of Mexico) ethnic heritage which makes her part of the Israel of God, but rather her belief in Jesus Christ.
She knows this; I wonder why many gentiles don't.
