5:12 {6} For we commend not ourselves again unto you, but give you occasion to glory on our behalf, that ye may have somewhat to [answer] them which glory in {k} appearance, and not in heart.
(6) He removes all suspicion of pride by a new reason, because it is a responsibility, not for his part but for theirs, that his apostleship be considered sincere compared to the vain display of a few others.
(k) In outward disguising, and that pretentious show of man's wisdom and eloquence, and not in true godliness, which is sealed in the heart.
5:12 We commend not ourselves again unto you, but rather gives them an opportunity of glorying over his work and life so that they can answer the false teachers who assail him.
5:12 We do not say this, as if we thought there was any need of again recommending ourselves to you, but to give you an occasion of rejoicing and praising God, and to furnish you with an answer to those false apostles who glory in appearance, but not in heart, being condemned by their own conscience.
5:9-15 The apostle quickens himself and others to acts of duty. Well-grounded hopes of heaven will not encourage sloth and sinful security. Let all consider the judgment to come, which is called, The terror of the Lord. Knowing what terrible vengeance the Lord would execute upon the workers of iniquity, the apostle and his brethren used every argument and persuasion, to lead men to believe in the Lord Jesus, and to act as his disciples. Their zeal and diligence were for the glory of God and the good of the church. Christ's love to us will have a like effect upon us, if duly considered and rightly judged. All were lost and undone, dead and ruined, slaves to sin, having no power to deliver themselves, and must have remained thus miserable for ever, if Christ had not died. We should not make ourselves, but Christ, the end of our living and actions. A Christian's life should be devoted to Christ. Alas, how many show the worthlessness of their professed faith and love, by living to themselves and to the world!
