Romans 11:21-31

21 For if God did not spare the natural branches, neither will he spare you.
22 Note then the kindness and the severity of God: severity toward those who have fallen, but God's kindness to you, provided you continue in his kindness; otherwise you too will be cut off.
23 And even the others, if they do not persist in their unbelief, will be grafted in, for God has the power to graft them in again.
24 For if you have been cut from what is by nature a wild olive tree, and grafted, contrary to nature, into a cultivated olive tree, how much more will these natural branches be grafted back into their own olive tree.
25 Lest you be wise in your own conceits, I want you to understand this mystery, brethren: a hardening has come upon part of Israel, until the full number of the Gentiles come in,
26 and so all Israel will be saved; as it is written, "The Deliverer will come from Zion, he will banish ungodliness from Jacob";
27 "and this will be my covenant with them when I take away their sins."
28 As regards the gospel they are enemies of God, for your sake; but as regards election they are beloved for the sake of their forefathers.
29 For the gifts and the call of God are irrevocable.
30 Just as you were once disobedient to God but now have received mercy because of their disobedience,
31 so they have now been disobedient in order that by the mercy shown to you they also may receive mercy.
