For the third time he was coming. Everything should be proved by the testimony of two or three witnesses; and this time he would not spare. The apostle says, "This is the third time I am coming"; yet he adds, "as if I were present the second time, and being absent now." This is, because he had been there once, was to have gone there on his way to Macedonia, was coming a second time, but did not on account of the state the Corinthians were in; but this third time he was coming, and he had told them beforehand; and he said beforehand, as if he had gone the second time, although now absent, that if he came again he would not spare.

He then puts an end to the question about his ministry by presenting an idea which ought to confound them utterly. If Christ had not spoken by him, Christ did not dwell in them. If Christ was in them, He must have spoken by the apostle, for he had been the means of their conversion. "Since," he says, "ye seek a proof that Christ speaketh in me, examine yourselves, whether ye be in the faith. Do ye not know yourselves, that Christ dwelleth in you, unless ye be reprobates?" and that they did not at all think. This was quite upsetting them, and turning their foolish and stupid opposition, their unbecoming contempt of the apostle, to their own confusion. What folly to allow themselves to be led away by a thought which, no doubt, exalted them in their own eyes; but which, by calling in question the apostleship of Paul, necessarily overturned, at the same time, their own Christianity!

From "which to you-ward is not weak" to the end of verse 4 is a parenthesis, referring to the character of his ministry, according to the principles brought forward in the previous chapter: weakness, and that which tended to contempt, on the side of man; power on God's part: even as Christ was crucified in weakness and was raised again by divine power. If the apostle himself was weak, it was in Christ; and he lived in Him, by the power of God, towards the Corinthians. Whatever might be the case with them, he trusted they should know that he was not reprobate; and he only prayed to God that they should do no evil, not in order that he should not be reprobate (that is, worthless in his ministry, for here he is speaking of ministry), but that they might do good even if he were reprobate. For he could do nothing against the truth, but for the truth. He was not master of the Corinthians for his own interest, but was content to be weak that they might be strong; for what he desired was their perfection. But he wrote, being absent, as he had said, in order that when present he might not be obliged to act with severity, according to the authority which the Lord had given him for edification, and not for destruction.

He had written what his heart, filled and guided by the Holy Ghost, impelled him to say; he had poured it all out; and now, wearied, so to speak, with the effort, he closes the epistle with a few brief sentences: -- "Rejoice, be perfect, be of good comfort, be of one mind, live in peace." Happen what might, it was this which he desired for them; and that the God of love and of peace should be with them. He rests in this wish, exhorting them to salute one another with affection, as all the saints, including himself, saluted them; praying that the grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Ghost, might be with them all.
