12 Not that we venture to class or compare ourselves with some of those who commend themselves. But when they measure themselves by one another, and compare themselves with one another, they are without understanding. 13 But we will not boast beyond limit, but will keep to the limits God has apportioned us, to reach even to you. 14 For we are not overextending ourselves, as though we did not reach you; we were the first to come all the way to you with the gospel of Christ. 15 We do not boast beyond limit, in other men's labors; but our hope is that as your faith increases, our field among you may be greatly enlarged, 16 so that we may preach the gospel in lands beyond you, without boasting of work already done in another's field.

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.
