24 Why, if he could graft you - branches cut from a tree out in the wild - into an orchard tree, he certainly isn't going to have any trouble grafting branches back into the tree they grew from in the first place. Just be glad you're in the tree, and hope for the best for the others.
25 I want to lay all this out on the table as clearly as I can, friends. This is complicated. It would be easy to misinterpret what's going on and arrogantly assume that you're royalty and they're just rabble, out on their ears for good. But that's not it at all. This hardness on the part of insider Israel toward God is temporary. Its effect is to open things up to all the outsiders so that we end up with a full house.
Matthew Henry's Commentary on Romans 11:24-25
Commentary on Romans 11:22-32
(Read Romans 11:22-32)
Of all judgments, spiritual judgments are the sorest; of these the apostle is here speaking. The restoration of the Jews is, in the course of things, far less improbable than the call of the Gentiles to be the children of Abraham; and though others now possess these privileges, it will not hinder their being admitted again. By rejecting the gospel, and by their indignation at its being preached to the Gentiles, the Jews were become enemies to God; yet they are still to be favoured for the sake of their pious fathers. Though at present they are enemies to the gospel, for their hatred to the Gentiles; yet, when God's time is come, that will no longer exist, and God's love to their fathers will be remembered. True grace seeks not to confine God's favour. Those who find mercy themselves, should endeavour that through their mercy others also may obtain mercy. Not that the Jews will be restored to have their priesthood, and temple, and ceremonies again; an end is put to all these; but they are to be brought to believe in Christ, the true become one sheep-fold with the Gentiles, under Christ the Great Shepherd. The captivities of Israel, their dispersion, and their being shut out from the church, are emblems of the believer's corrections for doing wrong; and the continued care of the Lord towards that people, and the final mercy and blessed restoration intended for them, show the patience and love of God.
