2 Corinthians 13:9

Moreover as he has eagerly endeavored this, so is he desirous also to show that his mind was quite joined to them; wherefore also he added, "For we rejoice when we are weak, and ye are strong. For this also we pray for even your perfecting." "For most certainly," he says, "we cannot do any thing against the truth, that is, punish you if you are well pleasing [to God]; besides, because we cannot, we therefore do not wish it, and even desire the contrary. Nay, we are particularly glad of this very thing, when we find you giving us no occasion to show that power of ours for punishment. For even if the doing of such things shows men glorious and approved and strong; still we desire the contrary, that ye should be approved and unblamable, and that we should never at any time reap the glory thence arising."

Wherefore he says, "For we are glad when we are weak." What is, "are weak?" "When we may be thought weak." Not when we are weak, but when we are thought weak; for they were thought so by their enemies, because they displayed not their power of punishing. "But still we are glad, when your behavior is of such a sort as to give us no pretence for punishing you. And it is a pleasure to us to be in this way considered weak, so that only ye be blameless;" wherefore he adds, "and ye are strong," that is, "are approved, are virtuous. And we do not only wish for this, but we pray for this, that ye may be blameless, perfect, and afford us no handle."

This is paternal affection, to prefer the salvation of the disciples before his own good name. This is the part of a soul free from vainglory; this best releaseth from the bonds of the body and makes one to rise aloft from earth to heaven, the being pure from vain-glory; just as therefore the contrary leadeth unto many sins.
