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.
30. glory of … infirmities—A striking contrast! Glorying or boasting of what others make matter of shame, namely, infirmities; for instance, his humbling mode of escape in a basket (2Co 11:33). A character utterly incompatible with that of an enthusiast (compare 2Co 12:5, 9, 10).
