11:22-33 The apostle gives an account of his labours and sufferings; not out of pride or vain-glory, but to the honour of God, who enabled him to do and suffer so much for the cause of Christ; and shows wherein he excelled the false apostles, who tried to lessen his character and usefulness. It astonishes us to reflect on this account of his dangers, hardships, and sufferings, and to observe his patience, perseverance, diligence, cheerfulness, and usefulness, in the midst of all these trials. See what little reason we have to love the pomp and plenty of this world, when this blessed apostle felt so much hardship in it. Our utmost diligence and services appear unworthy of notice when compared with his, and our difficulties and trials scarcely can be perceived. It may well lead us to inquire whether or not we really are followers of Christ. Here we may study patience, courage, and firm trust in God. Here we may learn to think less of ourselves; and we should ever strictly keep to truth, as in God's presence; and should refer all to his glory, as the Father of our Lord Jesus Christ, who is blessed for evermore.

29. I … weak—in condescending sympathy with the weak (1Co 9:22). "Care generates sympathy, which causes the minister of Christ personally to enter into the feelings of all his people, as if he stood in their position, so as to accommodate himself to all" [Calvin].

offended—by some stumbling-block put in his way by others: the "weak" is most liable to be "offended."

I burn not—The "I" in the Greek is emphatic, which it is not in the former clause, "I am not weak." I not only enter into the feeling of the party offended, but I burn with indignation at the offender, I myself taking up his cause as my own. "Who meets with a stumbling-block and I am not disturbed even more than himself" [Neander].
