The Gentiles Were Grafted In
(Romans 11:11-31) So I ask, did they [the Jews] stumble in order that they might fall?
By no means! Rather, through their trespass salvation has come to the Gentiles, so as to make Israel jealous.
(Romans 11:12) Now if their trespass means riches for the world, and if their failure means riches for the Gentiles, how much more will their full inclusion mean!
(Romans 11:13) Now I am speaking to you Gentiles. Inasmuch then as I am an apostle to the Gentiles, I magnify my ministry
(Romans 11:14) in order somehow to make my fellow Jews jealous, and thus save some of them.
For if their rejection means the reconciliation of the world, what will their acceptance mean but life from the dead? If the dough offered as firstfruits is holy, so is the whole lump, and if the root is holy, so are the branches.
(Romans 11:17) But if some of the branches were broken off, and you, although a wild olive shoot, were grafted in among the others and now share in the nourishing root of the olive tree, do not be arrogant toward the branches. If you are, remember it is not you who support the root, but the root that supports you. (Romans 11:19) Then you will say, “Branches were broken off so that I might be grafted in.” That is true. They were broken off because of their unbelief, but you stand fast through faith.
So do not become proud, but fear. For if God did not spare the natural branches, neither will he spare you.
(Romans 11:22) 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. (Romans 11:23) And even they, if they do not continue in their unbelief, will be grafted in, for God has the power to graft them in again. For if you were 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, (Romans 11:24) the natural branches, be grafted back into their own olive tree.
The Mystery of Israel's Salvation
Lest you be wise in your own sight, I do not want you to be unaware of this mystery, brothers: a partial hardening has come upon Israel, until the fullness of the Gentiles has come in.
(Romans 11:26) And in this way all Israel will be saved, as it is written, “The Deliverer will come from Zion, he will banish ungodliness from Jacob”; (Romans 11:27) “and this will be my covenant with them when I take away their sins.”
As regards the gospel, they are enemies for your sake. But as regards election, they are beloved for the sake of their forefathers.
(Romans 11:29) For the gifts and the calling of God are irrevocable. (Romans 11:30) For just as you were at one time disobedient to God but now have received mercy because of their disobedience, so they too have now been disobedient in order that by the mercy shown to you they also may now receive mercy.
