Paul announces that he is coming to the Corinthians for the third time, and reminds them that every matter must be settled on the evidence of two or three witnesses. He had warned them, and now repeats it while absent, to those who had sinned before and to all the rest, that when he comes again he will not spare them. This answers those who were seeking proof that Christ speaks in him. Paul affirms that Christ is not weak toward them but powerful among them. He was crucified in weakness, but lives by the power of God, and in the same way the apostles are weak in him but will live with him by the power of God toward them.
Then he invites them to examine themselves to see whether they are in the faith and to test themselves, for if Jesus Christ is in them they have not failed the test. He hopes they will recognize that Paul and his companions have not failed it. He prays to God that they do no wrong, not so that he may appear approved, but so that they may do what is right even if he appears to have failed. They can do nothing against the truth, only for the truth. He rejoices when he is weak and they are strong, and prays that they may be made complete, that is, restored.
For this reason he writes these things while absent, so that when he comes he will not have to use harshly the authority the Lord gave him for building up and not for tearing down. He concludes with a series of exhortations: rejoice, aim for restoration, comfort one another, agree with one another and live in peace, and the God of love and peace will be with them. He asks them to greet one another with a holy kiss, sends the greetings of all the saints and ends with the blessing: the grace of the Lord Jesus Christ, the love of God and the fellowship of the Holy Spirit be with them all.
