There isn't only spiritual Israel, there's also flesh and blood descendants of Israel. God's elect are the spiritual descendants of Israel but the flesh descendants were chosen by God to do all of Romans 9:4-5.
Rom 9:4 Who are Israelites; to whom pertaineth the adoption, and the glory, and the covenants, and the giving of the law, and the service of God, and the promises;
Rom 9:5 Whose are the fathers, and of whom as concerning the flesh Christ came, who is over all, God blessed for ever. Amen.
God is done with them now, all of the things above are completed. The fruit has been gathered, there is no use for them any more.

hmm, bare in mind though that as a Hebrew I would naturally see topics like this with a personal interest. That said though if you continue reading from Romans 9 over to chapter 11:25 do you see them no longer blinded and the fulness of the Gentiles complete or them still in use?
