John Chrysostom
Here, ascribing everything to God and calling suffering for Christ a grace, a bestowal, and a gift, he teaches them not to think highly of themselves. Therefore do not be ashamed of the gift. It is far more wondrous than the gift of raising the dead and working miracles. In the latter case I am the debtor, but in the former I have Christ as debtor. Therefore, since you have the gift, you must not only avoid being ashamed, but on the contrary rejoice. The Apostle calls virtues gifts, though not in the same sense as other gifts. The latter are wholly from God, while the former are also from us. Yet because God acts more even here, the Apostle says that all is His. He does not thereby reject free will, but disposes them to humility and thanksgiving.
