18 gives you no cause to crow over the pruned branches. Remember, you aren't feeding the root; the root is feeding you. 19 It's certainly possible to say, "Other branches were pruned so that I could be grafted in!" 20 Well and good. But they were pruned because they were deadwood, no longer connected by belief and commitment to the root. The only reason you're on the tree is because your graft "took" when you believed, and because you're connected to that belief-nurturing root. So don't get cocky and strut your branch. Be humbly mindful of the root that keeps you lithe and green. 21 If God didn't think twice about taking pruning shears to the natural branches, why would he hesitate over you? He wouldn't give it a second thought. 22 Make sure you stay alert to these qualities of gentle kindness and ruthless severity that exist side by side in God - ruthless with the deadwood, gentle with the grafted shoot. But don't presume on this gentleness. The moment you become deadwood, you're out of there. 23 And don't get to feeling superior to those pruned branches down on the ground. If they don't persist in remaining deadwood, they could very well get grafted back in. God can do that. He can perform miracle grafts. 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.

Commentary on Romans 11:11-21

(Read Romans 11:11-21)

The gospel is the greatest riches of every place where it is. As therefore the righteous rejection of the unbelieving Jews, was the occasion of so large a multitude of the Gentiles being reconciled to God, and at peace with him; the future receiving of the Jews into the church would be such a change, as would resemble a general resurrection of the dead in sin to a life of righteousness. Abraham was as the root of the church. The Jews continued branches of this tree till, as a nation, they rejected the Messiah; after that, their relation to Abraham and to God was, as it were, cut off. The Gentiles were grafted into this tree in their room; being admitted into the church of God. Multitudes were made heirs of Abraham's faith, holiness and blessedness. It is the natural state of every one of us, to be wild by nature. Conversion is as the grafting in of wild branches into the good olive. The wild olive was often ingrafted into the fruitful one when it began to decay, and this not only brought forth fruit, but caused the decaying olive to revive and flourish. The Gentiles, of free grace, had been grafted in to share advantages. They ought therefore to beware of self-confidence, and every kind of pride or ambition; lest, having only a dead faith, and an empty profession, they should turn from God, and forfeit their privileges. If we stand at all, it is by faith; we are guilty and helpless in ourselves, and are to be humble, watchful, afraid of self-deception, or of being overcome by temptation. Not only are we at first justified by faith, but kept to the end in that justified state by faith only; yet, by a faith which is not alone, but which worketh by love to God and man.

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.
