Romans 11:11-17

11:11 I ask then, they did not stumble into an irrevocable fall, did they? Absolutely not! But by their transgression salvation has come to the Gentiles, to make Israel jealous. 11:12 Now if their transgression means riches for the world and their defeat means riches for the Gentiles, how much more will their full restoration bring?

11:13 Now I am speaking to you Gentiles. Seeing that I am an apostle to the Gentiles, I magnify my ministry, 11:14 if somehow I could provoke my people to jealousy and save some of them. 11:15 For if their rejection is the reconciliation of the world, what will their acceptance be but life from the dead? 11:16 If the first portion of the dough offered is holy, then the whole batch is holy, and if the root is holy, so too are the branches.

Romans 11:24
