John Chrysostom

"I have therefore whereof I may glory, through Jesus Christ, in those things which pertain to God."

Inasmuch as he had humbled himself exceedingly, he again raised his style, doing this also for their sakes, lest he should seem to become readily an object of contempt. And while he raises himself, he remembers his own proper temper, and says, "I have therefore whereof to glory." I glory, he means, not in myself, not in our zeal, but in the "grace of God."
