Romans 11:23

20 True; by their unbelief they were broken off, and you stand by your faith. Don’t be conceited, but fear;

21 for if God didn’t spare the natural branches, neither will he spare you.

22 See then the goodness and severity of God. Toward those who fell, severity; but toward you, goodness, if you continue in his goodness; otherwise you also will be cut off.

23 They also, if they don’t continue in their unbelief, will be grafted in, for God is able to graft them in again.

24 For if you were cut out of that which is by nature a wild olive tree, and were grafted contrary to nature into a good olive tree, how much more will these, which are the natural branches, be grafted into their own olive tree?

25 For I don’t desire you to be ignorant, brothers, of this mystery, so that you won’t be wise in your own conceits, that a partial hardening has happened to Israel, until the fullness of the Gentiles has come in,

26 and so all Israel will be saved. Even as it is written, “There will come out of Zion the Deliverer, and he will turn away ungodliness from Jacob.
