2 Corinthians 9:15 - Joseph Benson’s Commentary on the Old and New Testaments

Thanks be to God for his unspeakable gift By this gift, for which the apostle so fervently thanks God, Dr. Whitby understands the charitable disposition that was in the Corinthians, Macedonians, and other sincere Christians, “by which God was glorified, the gospel adorned, the poor saints refreshed, and themselves fitted for an exceeding great reward.” The text, understood in this sense, is a clear proof that every good affection in the human heart is to be ascribed to a divine influence. But, as Macknight justly observes, “it may be doubted whether the apostle would call that gift unspeakable. So grand an epithet may, with more propriety, be applied to Christ. Besides the happy effects of a cordial friendship established between the [believing] Jews and Gentiles, now united in one faith, worship, and church, being the object of the apostle's present thoughts, it was natural for him to break forth in a thanksgiving to God for Christ, the author of that happy union, and of all the blessings which mankind enjoy. And as these blessings are so many and so great, that they cannot be fully declared in human language, Christ, the author of them all, may well be called God's unspeakable gift.”
