Romans 11:11-12, 17, 23-24

So, am I saying that Israel stumbled so badly that they will never get back up? Certainly not! Rather, it was because of their stumble that salvation now extends to all the non-Jewish people, in order to make Israel jealous and desire the very things that God has freely given them. So if all the world is being greatly enriched through their failure, and through their fall great spiritual wealth is given to the non-Jewish people, imagine how much more will Israel’s awakening bring to us all!

However, some of the branches have been pruned away. And you, who were once nothing more than a wild olive branch, God has grafted in—inserting you among the remaining branches as a joint partner to share in the wonderful richness of the cultivated olive stem.

God is more than ready to graft back in the natural branches when they turn from clinging to their unbelief to embracing faith. For if God grafted you in, even though you were taken from what is by nature a wild olive tree, how much more can he reconnect the natural branches by inserting them back into their own cultivated olive tree!
