2. Korinther 5:12

For--the reason why he leaves the manifestation of his sincerity in preaching to their consciences (Co2 3:1), namely, his not wishing to "commend" himself again. occasion to glory-- (Co2 1:14), namely, as to our sincerity. in appearance--Greek, "face" (compare Sa1 16:7). The false teachers gloried in their outward appearance, and in external recommendations (Co2 11:18) their learning, eloquence, wisdom, riches, not in vital religion in their heart. Their conscience does not attest their inward sincerity, as mine does (Co2 1:12).

Here observe, I. The apostle makes an apology for seeming to commend himself and his fellow-labourers (Co2 5:13), and tells them, 1. It was not to commend themselves, nor for their own sakes, that he had spoken of their fidelity and diligence in the former verses; nor was he willing to suspect their good opinion of him. But, 2. The true reason was this, to put an argument in their mouths wherewith to answer his accusers, who made vain boastings, and gloried in appearances only; that he might give them an occasion to glory on their behalf, or to defend them against the reproaches of their adversaries. And if the people can say that the word has been manifested to their consciences, and been effectual to their conversion and edification, this is the best defence they can make for the ministry of the word, when they are vilified and reproached.

Some of Paul's adversaries had, it is likely, reproached him for his zeal and fervour, as if he had been a madman, or, in the language of our days, a fanatic; they imputed all to enthusiasm, as the Roman governor told him, Much learning has made thee mad, Act 26:24. But the apostle tells them, 1. It was for the glory of God, and the good of the church, that he was thus zealous and industrious: "Whether we be beside ourselves, or whether we be sober (whether you or others do think the one or the other), it is to God, and for his glory: and it is for your cause, or to promote your good," Co2 5:13. If they manifested the greatest ardour and vehemency at some times, and used the greatest calmness in strong reasonings at other times, it was for the best ends; and in both methods they had good reason for what they did. For, 2. The love of Christ constrained them, Co2 5:14. They…
