Romans 11:15 - Joseph Benson’s Commentary on the Old and New Testaments

For As if he had said, Their general conversion ought to be desired, because of the admirable benefit which will come to mankind thereby: for if the casting away of them Their rejection, as signified above; be the reconciling of the world An occasion of sending the gospel to the Gentiles in all parts of the world, and so bringing them to faith in Christ, whereby they obtain the pardon of their sins, and reconciliation with God; what shall the receiving of them into God's favour and into his church be, but life from the dead A miraculous work, and productive of the greatest joy to the converted Gentiles; a joy like that which one would feel on receiving a beloved friend back from the dead. As, in the following verse, the apostle speaks of God's church under the emblem of a tree, Dr. Macknight thinks, in using the words η αποβολη, the casting away, “he may perhaps allude to the practice of gardeners, who cut off from vines and olive-trees such branches as are barren or withered, and cast them away. According to this notion of casting away, the reconciling of the world, or Gentiles, is the same thing with the ingrafting of them, mentioned Romans 11:17. In this passage the unbelief and rejection of the Jews is justly represented as the means of the reception of the Gentiles. For, although the unbelief of the Jews may seem to have been an obstacle to the conversion of the Gentiles, it hath greatly contributed to that event. Besides the reason mentioned in a preceding note, it is to be considered, that the rejection of the Jews was the punishment of their unbelief, and that both events were foretold by Moses and by Christ. Wherefore these events, as the fulfilment of prophecy, have strengthened the evidences of the gospel, and thereby contributed to the conversion of the Gentiles.” Add to this, there are many other predictions in the Old Testament, which demonstrate the truth of the gospel, but which derive their strength from their being in the possession of the Jews, in whose hands they have continued from the beginning, and who have preserved them with the greatest care, carrying them with them in all their dispersions, wherever they go. In all countries, therefore, the Jews are living witnesses to the antiquity and genuineness of the whole of the prophecies by which the gospel is confirmed. And their testimony, which is always at hand, cannot be called in question; because, having shown themselves from the beginning bitter enemies of Christ and of his gospel, no suspicion can be entertained that they have either forged these prophecies, or altered them to favour us. As little can it be suspected that we have forged or altered these prophecies. For if any of us had been disposed so to do, it would have served no purpose while our enemies, the Jews, maintained the integrity of their copies.
