John Chrysostom, on Heb 12:11

“Now all chastisement for the present indeed seemeth not to bring with it joy, but sorrow: but afterwards it will yield, to them that are exercised by it, the most peaceable fruit of justice.”

“Ye are suffering, he says. For such is chastisement; such is its beginning. For "no chastening for the present seemeth to be joyous but grievous." Well said he, "seemeth not," Chastisement he means is not grievous but "seemeth" so. "All chastisement": not this and that, but "all," both human and spiritual. Seest thou that he argues from our common notions? "Seemeth" (he says) "to be grievous," so that it is not really so. For what sort of grief brings forth joy? So neither does pleasure bring forth despondency. "Nevertheless, afterward it yieldeth the peaceable fruits of righteousness to them which have been exercised thereby." Not "fruit" but "fruits," a great abundance. "To them" (he says) "which have been exercised thereby." What is "to them which have been exercised thereby"? To them that have endured for a long while, and been patient. And he uses an auspicious expression. So then, chastisement is exercise, making the athlete strong, and invincible in combats, irresistible in wars. If then "all chastisement" be such, this also will be such: so that we ought to look for good things, and for a sweet and peaceful end. And do not wonder if, being itself hard, it has sweet fruits; since in trees also the bark is almost destitute of all quality, and rough; but the fruits are sweet. But he took it from the common notion. If therefore we ought to look for such things, why do ye vex yourselves? Why, after ye have endured the painful, do ye despond as to the good? The distasteful things which ye had to endure, ye endured: do not then despond as to the recompense.”
