Romans 11:21-29

21For if God spared not the natural branches, take heed lest he also spare not thee. 22Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness, if thou continue in his goodness: otherwise thou also shalt be cut off.

23And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again. 24For if thou wert cut out of the olive tree which is wild by nature, and wert graffed contrary to nature into a good olive tree: how much more shall these, which be the natural branches, be graffed into their own olive tree? 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 Zion 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 fathers’ sakes. 29For the gifts and calling of God are without repentance.
