Here we have,

I.The apostle's prayer to God on the behalf of the Corinthians, that they might do no evil, Co2 13:7. This is the most desirable thing we can ask of God, both for ourselves and for our friends, to be kept from sin, that we and they may do no evil; and it is most needful that we often pray to God for his grace to keep us, because without this we cannot keep ourselves. We are more concerned to pray that we may not do evil than that we may not suffer evil.

II.The reasons why the apostle put up this prayer to God on behalf of the Corinthians, which reasons have a special reference to their case, and the subject-matter about which he was writing to them. Observe, he tells them, 1. It was not so much for his own personal reputation as for the honour of religion: "Not that we should appear approved, but that you should do that which is honest, or decent, and for the credit of religion, though we should be reproached and vilified, and accounted as reprobates," Co2 13:7. Note, (1.) The great desire of faithful ministers of the gospel is that the gospel they preach may be honoured, however their persons may be vilified. (2.) The best way to adorn our holy religion is to do that which is honest, and of good report, to walk as becomes the gospel of Christ. 2. Another reason was this: that they might be free from all blame and censure when he should come to them. This is intimated in Co2 13:8, We can do nothing against the truth, but for the truth. If therefore they did not do evil, nor act contrary to their profession of the gospel, the apostle had no power nor authority to punish them. He had said before (Co2 10:8) and says here (Co2 13:10) that the power which the Lord had given him was to edification, not to destruction; so that, although the apostle had great powers committed to him for the credit and advancement of the gospel, yet he could not do anything to the disparagement of the truth, nor the discouragement of those who obeyed it. He could not, that is, he would not, he dared not, he had no commission to act against the truth; and it is remarkable how the apostle did rejoice in this blessed impotency: "We are glad," says he (Co2 13:9), "when we are weak and you are strong; that is, that we have no power to censure those who are strong in faith and fruitful in good works." Some understand this passage thus: "Though we are weak through persecutions and contempt, we bear it patiently, and also joyfully, while we see that you are strong, that you are prosperous in holiness, and persevering in well-doing." For, 3. He desired their perfection (Co2 13:9); that is, that they might be sincere, and aim at perfection (sincerity is our gospel-perfection), or else he wished there might be a thorough reformation among them. He not only desired that they might be kept from sin, but also that they might grow in grace, and increase in holiness, and that all that was amiss among them might be rectified and reformed. This was the great end of his writing this epistle, and that freedom he used with them by writing these things (those friendly admonitions and warnings), being absent, that so, being present, he should not use sharpness (Co2 13:10), that is, not proceed to the utmost extremity in the exercise of the power which the Lord had given him as an apostle, to revenge all disobedience, Co2 10:6.

Therefore I write these things - I only threaten you now, by this epistle, to put you on your guard, and lead you to reformation before I visit you that I may not then have to use sharpness, αποτομια, a cutting off, employing thus my apostolical authority to inflict punishment; a power which God has given me, rather to be employed in your edification than in your destruction.

Since ye seek a proof of Christ - The conversion of the Corinthians was to themselves a solid proof that Christ spoke by the apostle; and therefore he could, with great propriety, say that this power of Christ, far from being weak, was mighty among them.

Therefore I write these things being absent,.... Assuring them of his power and authority, expressing his concern for their welfare, earnestly desiring that they might be kept from evil, and perform good works; and that they might be in a more honourable, orderly, and comfortable situation, whilst he was absent from them, and before he came among them:

lest, being present, I should use sharpness; meaning severe reproofs and censures, or rather the exercise of the apostolic rod:

according to the power the Lord haft given me, to edification, and not to destruction; by striking persons dead, as Ananias and Sapphira were by Peter; or by delivering them up to Satan to have corporeal punishment inflicted on them, as were Hymenaeus and Philetus, and the incestuous person by the Apostle Paul; which, though it was for the destruction of the flesh, yet for the salvation of their souls, and for the good, use, and edification of the rest of the society, that they might take warning thereby, and shun the evils which were the occasion of such severity.

Therefore--because I wish the "sharpness" to be in my letters rather than in deeds [CHRYSOSTOM].

edification . . . not to destruction--for building up . . . not for casting down. To "use sharpness" would seem to be casting down, rather than building up; therefore he prefers not to have to use it.
