2 Corinthians 10:12-18 New Revised Standard Version (NRSV)
12 We do not dare to classify 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 do not show good sense. 13 We, however, will not boast beyond limits, but will keep within the field that God has assigned to us, to reach out even as far as you. 14 For we were not overstepping our limits when we reached you; we were the first to come all the way to you with the good news[a] of Christ. 15 We do not boast beyond limits, that is, in the labors of others; but our hope is that, as your faith increases, our sphere of action among you may be greatly enlarged, 16 so that we may proclaim the good news[b] in lands beyond you, without boasting of work already done in someone else’s sphere of action. 17 “Let the one who boasts, boast in the Lord.” 18 For it is not those who commend themselves that are approved, but those whom the Lord commends.
