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.

AD 400
Paul is testifying that God makes provision for those who have done well, while at the same time he allows them to be cast down by various trials. This is both so that they shall not be deprived of the fruits of their labors and that they may be enriched by their trials so that they may have even greater eternal rewards. Commentary on Paul’s Epistles.
