12 We do not dare to classify or compare ourselves with some who commend themselves. When they measure themselves by themselves and compare themselves with themselves, they are not wise. 13 We, however, will not boast beyond proper limits, but will confine our boasting to the sphere of service God himself has assigned to us, a sphere that also includes you. 14 We are not going too far in our boasting, as would be the case if we had not come to you, for we did get as far as you with the gospel of Christ. 15 Neither do we go beyond our limits by boasting of work done by others. Our hope is that, as your faith continues to grow, our sphere of activity among you will greatly expand, 16 so that we can preach the gospel in the regions beyond you. For we do not want to boast about work already done in someone else's territory. 17 But, "Let the one who boasts boast in the Lord."[1] 18 For it is not the one who commends himself who is approved, but the one whom the Lord commends.

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.
