To the ones saying Romans 11 speaks of two groups. The passage in question speaks of Israel and Israel alone, it starts after Paul warns the gentile church not to be proud, because if God did not spare the natural branches (Israel) he will not spare us either, and also about the mystery of Israel only being blinded in part UNTIL the time of the gentile is complete
because at that time, all Isreal will be saved,
it is in this context that he says Israel at this time is hated because of the gospel but beloved because of the fathers, the gifts and calling of Gods are irrevocable,
this of course speaks of the gift given to the fathers, and the same gift God will give Isreal when they repent, and they are restored. As prophesied in all the places I have shown.
