Romans 11:5-6, 25-27

Even so then at this present time also there is a remnant according to the election of grace. But if it is by grace, it is no more of works: otherwise grace is no more grace.

For I would not, brethren, have you ignorant of this mystery, lest ye be wise in your own conceits, that a hardening in part hath befallen Israel, until the fulness of the Gentiles be come in; and so all Israel shall be saved: even as it is written, There shall come out of Zion the Deliverer; He shall turn away ungodliness from Jacob: And this is my covenant unto them, When I shall take away their sins.
