In these verses the apostle addresses himself to the Corinthians two ways: -

I.He blames them for what was faulty in them; namely, that they had not stood up in his defence as they ought to have done, and so made it the more needful for him to insist so much on his own vindication. They in manner compelled him to commend himself, who ought to have been commended of them Co2 12:11. And had they, or some among them, not failed on their part, it would have been less needful for him to have said so much on his own behalf. He tells them further that they in particular had good reason to speak well of him, as being in nothing behind the very chief apostles, because he had given them full proof and evidence of his apostleship; for the signs of an apostle were wrought among them in all patience, in signs, and wonders, and mighty deeds. Note, 1. It is a debt we owe to good men to stand up in the defence of their reputation; and we are under special obligations to those we have received benefit by, especially spiritual benefit, to own them as instruments in God's hand of good to us, and to vindicate them when they are calumniated by others. 2. How much soever we are, or ought to be, esteemed by others, we ought always to think humbly of ourselves. See an example of this in this great apostle, who thought himself to be nothing, though in truth he was not behind the greatest apostles - so far was he from seeking praise from men, though he tells them their duty to vindicate his reputation - so far was he from applauding himself, when he was forced to insist upon his own necessary self-defence.

II.He gives a large account of his behaviour and kind intentions towards them, in which we may observe the character of a faithful minister of the gospel. 1. He was not willing to be burdensome to them, nor did he seek theirs, but them. He says (Co2 12:13) he had not been burdensome to them, for the time past, and tells them (Co2 12:14) he would not be burdensome to them for the time to come, when he should come to them. He spared their purses, and did not covet their money: I seek not yours but you. He sought not to enrich himself, but to save their souls: he did not desire to make a property of them to himself, but to gain them over to Christ, whose servant he was. Note, Those who aim at clothing themselves with the fleece of the flock, and take no care of the sheep, are hirelings, and not good shepherds. 2. He would gladly spend and be spent for them (Co2 12:15); that is, he was willing to take pains and to suffer loss for their good. He would spend his time, his parts, his strength, his interest, his all, to do them service; nay, so spend as to be spent, and be like a candle, which consumes itself to give light to others. 3. He did not abate in his love to them, notwithstanding their unkindness and ingratitude to him; and therefore was contented and glad to take pains with them, though the more abundantly he loved them the less he was loved, Co2 12:15. This is applicable to other relations: if others be wanting in their duty to us it does not follow therefore that we may neglect our duty to them. 4. He was careful not only that he himself should not be burdensome, but that none he employed should. This seems to be the meaning of what we read, Co2 12:16-18. If it should be objected by any that though he did not himself burden them, yet, being crafty, he caught them with guile, that is, he sent those among them who pillaged them, and afterwards he shared with them in the profit: "This was not so," says the apostle; "I did not make a gain of you myself, nor by any of those whom I sent; nor did Titus, nor any others - We walked by the same spirit and in the same steps." They all agreed in this matter to do them all the good they could, without being burdensome to them, to promote the gospel among them and make it as easy to them as possible. Or, this may be read with an interrogation, as utterly disclaiming any guile in himself and others towards them. 5. He was a man who did all things for edifying, Co2 12:19. This was his great aim and design, to do good, to lay the foundation well, and then with care and diligence to build the superstructure. 6. He would not shrink from his duty for fear of displeasing them, though he was so careful to make himself easy to them. Therefore he was resolved to be faithful in reproving sin, though he was therein found to be such as they would not, Co2 12:20. The apostle here mentions several sins that are too commonly found among professors of religion, and are very reprovable: debates, envyings, wraths, strifes, backbitings, whisperings, swellings, tumults; and, though those who are guilty of these sins can hardly bear to be reproved for them, yet faithful ministers must not fear offending the guilty by sharp reproofs, as they are needful, in public and in private. 7. He was grieved at the apprehension that he should find scandalous sins among them not duly repented of. This, he tells them, would be the cause of great humiliation and lamentation. Note, (1.) The falls and miscarriages of professors cannot but be a humbling consideration to a good minister; and God sometimes takes this way to humble those who might be under temptation to be lifted up: I fear lest my God will humble me among you. (2.) We have reason to bewail those who sin and do not repent, to bewail many that have sinned, and have not repented, Co2 12:21. If these have not, as yet, grace to mourn and lament their own case, their case is the more lamentable; and those who love God, and love them, should mourn for them.

The signs of an apostle were wrought among you - Though I have been reputed as nothing, I have given the fullest proof of my Divine mission by various signs, wonders, and miracles, and by that patience which I have manifested towards you: though I had power from God to inflict punishment on the transgressors, I have in every case forborne to do it. Is the man nothing who wrought such miracles among you?

Behold, the third time I am ready to come to you,.... Not that he had been twice at Corinth, and was now about to come a third time; for as yet he had been but once there, when he first preached to them, was the means of their conversion, and settled them in a church state; he had promised them to come a second time, but as yet was prevented; see Co1 16:5, and now a third time he had purposed it in his mind, and had prepared for it, and was just ready to come unto them; when he assures them he had not altered his mind, nor should he change his conduct, but steer the same course he had:

and I will not be burdensome to you; he signifies he would preach the Gospel freely to them, and take nothing of them; and this he says lest they should think with themselves, that though he took no stipend of them before, yet when he came again he would:

for I seek not yours; their money and substance, as did the false apostles:

but you; they themselves, their spiritual good and welfare, the comfort, edification, instruction, and salvation of their immortal souls; like a good and faithful shepherd, who sought not the fleece, but the good of the flock; or rather like a loving tender father, that was affectionately concerned for the good of his children:

for the children ought not to lay up for the parents, but the parents for the children; not but that children ought to take care of, and provide for their aged and indigent parents, and churches ought to maintain their faithful ministers; but the apostle argues from a common fact which nature and affection direct unto, and have formed into a sort of a law, that parents not only care for their children, bring them up, and provide for them food and raiment; but as they are blessed by Providence, lay up treasures for them for tithe to come, and not children for their parents; this is neither usual nor necessary, for however, as the case may be, children may be obliged to maintain their parents when grown old and in want, yet not to lay up substance for them for futurity; and by it the apostle suggests, that he was a spiritual father to these Corinthians, and they were his children; for whose spiritual welfare he had the highest concern, and whatever he did was out of no disrespect to them, but from the strongest affection for them.

Truly, &c.--There is understood some such clause as this, "And yet I have not been commended by you."

in all patience, in signs, &c.--The oldest manuscripts omit "in." "Patience" is not one of the "signs," but the element IN which they were wrought: endurance of opposition which did not cause me to leave off working [ALFORD]. Translate, "IN . . . patience, BY signs," &c. His mode of expression is modest, putting himself, the worker, in the background, "were wrought," not "I wrought." As the signs have not been transmitted to us, neither has the apostleship. The apostles have no literal successors (compare Act 1:21-22).

mighty deeds--palpable works of divine omnipotence. The silence of the apostles in fourteen Epistles, as to miracles, arises from the design of those Epistles being hortatory, not controversial. The passing allusions to miracles in seven Epistles prove that the writers were not enthusiasts to whom miracles seem the most important thing. Doctrines were with them the important matter, save when convincing adversaries. In the seven Epistles the mention of miracles is not obtrusive, but marked by a calm air of assurance, as of facts acknowledged on all hands, and therefore unnecessary to dwell on. This is a much stronger proof of their reality than if they were formally and obtrusively asserted. Signs and wonders is the regular formula of the Old Testament, which New Testament readers would necessarily understand of supernatural works. Again, in the Gospels the miracles are so inseparably and congruously tied up with the history, that you cannot deny the former without denying the latter also. And then you have a greater difficulty than ever, namely, to account for the rise of Christianity; so that the infidel has something infinitely more difficult to believe than that which he rejects, and which the Christian more rationally accepts.
