10:12-18 If we would compare ourselves with others who excel us, this would be a good method to keep us humble. The apostle fixes a good rule for his conduct; namely, not to boast of things without his measure, which was the measure God had distributed to him. There is not a more fruitful source of error, than to judge of persons and opinions by our own prejudices. How common is it for persons to judge of their own religious character, by the opinions and maxims of the world around them! But how different is the rule of God's word! And of all flattery, self-flattery is the worst. Therefore, instead of praising ourselves, we should strive to approve ourselves to God. In a word, let us glory in the Lord our salvation, and in all other things only as evidences of his love, or means of promoting his glory. Instead of praising ourselves, or seeking the praise of men, let us desire that honour which cometh from God only.
12. "We do not presume (irony) to judge ourselves among, or in comparison with, some of them that commend themselves." The charge falsely brought against him of commending himself (2Co 3:1; 5:12), really holds good of the false teachers. The phrase, "judge ourselves of the number," is drawn from the testing of athletes and senators, the "approved" being set down on the roll [Wahl].
measuring themselves by themselves—"among themselves": to correspond to the previous verb, "judge ourselves among them." Instead of measuring themselves by the public standard, they measure themselves by one made by themselves: they do not compare themselves with others who excel them, but with those like themselves: hence their high self-esteem. The one-eyed is easily king among the blind.
are not wise—with all their boasted "wisdom" (1Co 1:19-26), they are anything but "wise."
