Romans 11:23-29

23And they also, 1if they do not continue in their unbelief, will be grafted in; for God is able to graft them in again. 24For if you were cut off from what is by nature a wild olive tree, and contrary to nature were grafted into a cultivated olive tree, how much more will these who are the natural branches be grafted into their own olive tree?

25For 2I do not want you, brothers and sisters, to be uninformed of this 3mystery--so that you will not be 4wise in your own estimation--that a partial 5hardening has happened to Israel until the 6fullness of the Gentiles has come in; 26and so all Israel will be saved; just as it is written: “7The Deliverer will come from Zion, He will remove ungodliness from Jacob.”27“8This is 9My covenant with them, 10When I take away their sins.” 28In relation to the gospel they are 11enemies on your account, but in relation to God’s choice they are beloved 12on account of the fathers; 29for the gifts and the 13calling of God 14are irrevocable.
