Concerning the present physical promises to Israel contained in the four unconditional covenants, how would we expect saved Jews (say, living in Israel) to experience them today?

They would experience the spiritual promises of the unconditional covenants, of course, in the same way as Gentile believers (the indwelling of the Spirit; removal of sin; etc.). In the physical realm, the fact that the Jewish believers in Israel are able to live in the Land would mean they are enjoying the physical benefits of the covenants as Jewish possession of the Land is based upon the covenants – even during the long period of only partial possession. Insofar as God may bless Israel materially, Jewish believers would, therefore, share in that material blessing, whatever it my be. Also in keeping with the Land Covenant, if God should render judgment upon the nation, Jewish believers would also share in that. On a broader scale, the fact that at least a quarter million Jewish believers died in the Holocaust makes it quite clear that whatever happens to Israel in the physical realm – both in blessing and cursing – Jewish believers partake of both just by virtue of being a member of the nation, Israel. Therefore, Jewish believers also suffer anti-Semitism.
