| Geneva Study Bible For if God spared not the {u} natural branches, take heed lest he also spare not thee. (u) He calls them natural, not because they had any holiness by nature, but because they were born of those whom the Lord set apart for himself from other nations, by his league and covenant which he freely made with them. People's New Testament 11:21 For if God spared not the natural branches, the Jews, but broke them off on account of their unbelief, certainly he would not spare the Gentile, not a natural branch, if he was an unbeliever. Wesley's Notes 11:21 Be not highminded, but fear - We may observe, this fear is not opposed to trust, but to pride and security. Jamieson-Fausset-Brown Bible Commentary 21. For if God spared not the natural branches-sprung from the parent stem. take heed lest he also spare not thee-a mere wild graft. The former might, beforehand, have been thought very improbable; but, after that, no one can wonder at the latter. Matthew Henry's Concise Commentary 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. |
