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. 17 But “he who glories, let him glory in the Lord.” 18 For not he who commends himself is approved, but whom the Lord commends. (2 Corinthians 10:15–18, NKJV)
The apostle Paul energetically preached the gospel and fulfilled his ministry with faithful zeal. We can learn lessons by observing his gospel labors. First, Paul did not boast in other men’s labors (v. 15-16). That is, he gave credit where credit was due. He did not take credit for another person’s work. This trait of genuine meekness always serves the cause of the gospel. We should imitate Paul by admiring and encouraging others’ faithful work instead of trying to “ride their coattails” and elevate ourselves. Secondly, Paul did not boast in himself (v. 18). Self-commendation can color an honest examination of ourselves and our work for the Lord (Gal. 6:3-4). “Let another man praise you, and not your own mouth; A stranger, and not your own lips” (Prov. 27:2). Thirdly, Paul boasted in the Lord instead of himself (v. 17). He could say, “For when I am weak, then I am strong” in the Lord (2 Cor. 12:10). Our faith must be in the strength of the Lord, not ourselves. Fourthly, Paul sought the Lord’s approval above all (v. 18). So, he worked diligently to be approved by God (cf. 2 Tim. 2:15; 4:7-8). In whose approval do we boast, men’s or God’s?
