2. Korinther 1:12

For--reason why he may confidently look for their prayers for him. our rejoicing--Greek, "our glorying." Not that he glories in the testimony of his conscience, as something to boast of; nay, this testimony is itself the thing in which his glorying consists. in simplicity--Most of the oldest manuscripts read, "in holiness." English Version reading is perhaps a gloss from Eph 6:5 [ALFORD]. Some of the oldest manuscripts and versions, however, support it. godly sincerity--literally, "sincerity of God"; that is, sincerity as in the presence of God (Co1 5:8). We glory in this in spite of all our adversities. Sincerity in Greek implies the non-admixture of any foreign element. He had no sinister or selfish aims (as some insinuated) in failing to visit them as he had promised: such aims belonged to his adversaries, not to him (Co2 2:17). "Fleshly wisdom" suggests tortuous and insincere courses; but the "grace of God," which influenced him by God's gifts (Rom 12:3; Rom 15:15), suggests holy straightforwardness and sincere faithfulness to promises (Co2 1:17-20), even as God is faithful to His promises.

And here take notice, Conscience witnessed, (1.) Concerning their conversation, their constant course and tenour of life: by that we may judge of ourselves, and not by this or that single act. (2.)
