It is this last aspect of his confidence which is expanded in the fifth verse: "not that we are sufficient of ourselves, to account anything as from ourselves; but our sufficiency is from God." This vehement disclaimer of any self-sufficiency has naturally been taken in the widest sense, and theologians from Augustine downward have found in it one of the most decisive proofs of the inability of man for any spiritual good accompanying salvation. No one, we may be sure, would have ascribed salvation, and all spiritual good accompanying it, entirely to God with more hearty sincerity than the Apostle; but it does seem better here to give his words a narrower and more relevant interpretation. The "sufficiency to account anything," of which he speaks, must have a definite meaning for the context; and this meaning is suggested by the words of chap. ii. 14-17. Paul would never have dared, he tells us--indeed, he would never have been able--on his own motion, and out of his own resources, either to form conclusions, or to express them, on the subjects there in view. It is not for any man at random to say what the true Gospel is, what are its issues, what the responsibilities of its hearers or preachers, what is the spirit requisite in the evangelist, or what are the methods legitimate for him. The Gospel is God's concern, and only those who have been capacitated by Him are entitled to speak as Paul has spoken. If this is a narrower sense than that which is expounded so vigorously by Calvin, it is more pertinent, and some will find it quite as pungent. Of all things that are done hastily and inconsiderately, by people calling themselves Christian, the criticism of evangelists is one of the most conspicuous. At his own prompting, out of his own wise head, any man almost will both make up his mind and speak his mind about any preacher with no sense of responsibility whatever. Paul certainly did form opinions about preachers, opinions which were anything but flattering; but he did it through Jesus Christ and in relation to God; he did it because, as he writes, God had made him sufficient, _i.e._ had given him capacity to be, and the capacity of, a true evangelist, so that he knew both what the Gospel was, and how it ought to be proclaimed. It would silence much incompetent, because self-sufficient, criticism, if no one "thought anything" who had not this qualification.
