(18) Thou bearest not the root.--There can be no boasting, for the privileges which the Gentiles possess are derived, and not original.

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.Boast not against the branches,.... Those that were broken off: the apostle would not have them vaunt it over them, despise them, and trample upon them; but pity them, and pray for and be abundantly thankful and humbled before God, under a sense of Ida sovereign and distinguishing grace, who had settled them in a Gospel church state, who were before comparable to a wild olive tree; and much less should they glory over the believing Jews, among whom they were, there being no difference between them, for they were all one in Christ Jesus:

but if thou boast; but if such a vain temper of mind should prevail, he suggests they would do well to sit down and consider what little reason they had on their side to glory; and if such glorying and boasting, one against another was lawful, the Jews had the greatest reason for it; for, adds the apostle,

thou bearest not the root, but the root thee. The Jews received no advantages from the Gentiles, but on the contrary the Gentiles from the Jews, to whom were committed the oracles of God, and by whom they were faithfully kept and transmitted to the Gentiles; the Gospel itself came out first from among them; the first preachers of it were Jews, who carried it into the Gentile world, where it was greatly succeeded to the conversion of many, who by this means were brought into a Gospel church state, and so enjoyed all the privileges they did: yea, Christ himself, according to the flesh, came of them, was sent unto them, was the minister of them, lived and died among them, and wrought out the great salvation for his people; hence "salvation" itself is said to be "of the Jews", John 4:22, so that the root and foundation of all their enjoyments were from the Jews, and not those of the Jews from them; hence there was no room, nor reason, for boasting against them, and vaunting it over them.
