Romans 11
25For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
26And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob:
27For this is my covenant unto them, when I shall take away their sins.
28As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the father's sakes.
29For the gifts and calling of God are without repentance.
Sorry, I don't see the significance of your quoting Romans 11.
