And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me, lest I should be exalted above measure.
All Commentaries on 2 Corinthians 12:7 Go To 2 Corinthians 12
Augustine of Hippo
AD 430
Not everyone who spares is a friend, nor is everyone who strikes an enemy… Love mingled with severity is better than deceit with indulgence. It is more profitable for bread to be taken away from the hungry, if he neglects right living because he is sure of his food, than for bread to be broken to the hungry, to lead him astray into compliance with wrongdoing. The one who confines the madman, as well as the one who rouses the lethargic, is troublesome to both but loves both. Who could love us more than God does? Yet he continually teaches us sweetly as well as frightens us for our good. Often adding the most stinging medicine of trouble to the gentle remedies with which he comforts us, he tries the patriarchs, even good and devout ones, by famine; he chastises a stubborn people with heavier punishments; he does not take away from the apostle the sting of the flesh, though asked three times, so as to perfect strength in weakness. Letter , To Vincent.
