(21) Take heed lest . . .--The better reading seems to be to omit these words, neither will He spare thee.

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.For if God spared not the natural branches,.... That is, executed his righteous judgments, inflicted due punishment upon the Jews, unchurched them, and stripped them of those privileges they enjoyed in a church state; who were the natural descendants of Abraham; were naturally, and as born into the world, in a national church state and in that national covenant God made with that people; to whom belonged a national adoption, in which sense they were the sons of God, his firstborn; they were chosen by him as a special and peculiar people, to very great favours and privileges; they were Christ's own, he came of them according to the flesh, and was particularly sent unto them, and ministered among them; wherefore, if, at last, God did not spare this people, though he had for a long time done it, but stirred up all his wrath against them, they disbelieving his Son, rejecting and despising the Messiah, and salvation by him, this should awaken the fear, care, and caution of the Gentiles in a church state, lest if they behave not well, he should deal in like manner with them:

take heed lest he also spare not thee; for whatever was done to the Jews in former or latter times, are written for the instruction and admonition of Gentiles; and the use they are to make thereof is, to be careful and cautious, lest by imbibing principles derogatory from the grace of God and glory of Christ, or by an unbecoming walk and conversation they provoke the Lord to unchurch them as he has done the Jews before them; and which they may the rather fear, since the Jews were the natural branches, and they formerly strangers and aliens.
