12 For we dare not class ourselves or compare ourselves with those who commend themselves. But they, measuring themselves by themselves, and comparing themselves among themselves, are not wise. 13 We, however, will not boast beyond measure, but within the limits of the sphere which God appointed us--a sphere which especially includes you. 14 For we are not overextending ourselves (as though our authority did not extend to you), for it was to you that we came with the gospel of Christ; 15 not boasting of things beyond measure, that is, in other men's labors, but having hope, that as your faith is increased, we shall be greatly enlarged by you in our sphere, 16 to preach the gospel in the regions beyond you, and not to boast in another man's sphere of accomplishment.
Matthew Henry's Commentary on 2 Corinthians 10:12-16
Commentary on 2 Corinthians 10:12-18
(Read 2 Corinthians 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.
