2 Corinthians 10:18

"For not he that commendeth himself is approved, but whom the Lord commendeth." He did not say, we are so, "but whom the Lord commendeth." Seest thou how modestly he speaks? But if as he proceeds he stirreth up loftier words, wonder not, for this also cometh of Paul's prudence. For if he had gone on in every part to speak lowly words, he would not have hit these men so effectually, nor have extricated the disciples from their error. For it is possible both by modesty ill-timed to do harm, and by saying something admirable of one's self at a proper time to do good. As therefore he also did. For there was no little danger in the disciples being persuaded into any mean opinion of Paul. Not that Paul sought the glory that cometh of men. For had he sought this, he would not have kept silence so long on those great and marvellous matters of "fourteen years ago;" (Chap. xii. 20) nor would he, when necessity was laid upon him, have so shrunk back and hesitated to speak of them; very evidently he would not even then have spoken, had he not been compelled. Certainly then it was not from a desire after the glory which cometh from men that he said these things, but out of tender care for the disciples. For since they cast reproaches at him as a braggart, and as boastful in words but able to show nothing in deeds, he is compelled subsequently to come to those revelations. Although he had it in his power to convince them by his deeds, at the time when he said these things: yet he still persists, nevertheless, in using menaces in words. For he was most especially free from vain-glory; and this his whole life proves, both before and after this.
