Matthew Henry on the Sufficiency of God

"[Paul] utterly disclaims the taking of any praise to themselves, and ascribes all the glory to God: "We are not sufficient of ourselves, v. 5. We could never have made such good impressions on your hearts, nor upon our own. Such are our weakness and inability that we cannot of ourselves think a good thought, much less raise any good thoughts or affections in other men. All our sufficiency is of God; to him therefore are owing all the praise and glory of that good which is done, and from him we must receive grace and strength to do more.’’ This is true concerning ministers and all Christians; the best are no more than what the grace of God makes them. Our hands are not sufficient for us, but our sufficiency is of God; and his grace is sufficient for us, to furnish us for every good word and work." M. Henry on 2 Cor 3:5
