12 Not that we dare to classify or compare ourselves with some of those who are commending 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 limits, but will boast only with regard to the area of influence God assigned to us, to reach even to you. 14 For we are not overextending ourselves, as though we did not reach you. For we were the first to come all the way to you with the gospel of Christ. 15 We do not boast beyond limit in the labors of others. But our hope is that as your faith increases, our area of influence 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 area of influence. 17 “Let the one who boasts, boast in the Lord.” 18 For it is not the one who commends himself who is approved, but the one whom the Lord commends. (ESV)
