John Chrysostom, on Heb 12:10

“And they indeed for a few days, according to their own pleasure, instructed us: but he, for our profit, that we might receive his sanctification.”

“However the difference arises not from this alone, nor from the persons, but also from the cause itself, and from the fact. For it is not on the same grounds that He and they inflict chastisement: but they did it with a view to "what seemed good to them," that is, fulfilling their own pleasure oftentimes, and not always looking to what was expedient. But here, that cannot be said. For He does this not for any interest of His own but for you, and for your benefit alone. They did it that ye might be useful to themselves also, oftentimes without reason; but here there is nothing of this kind. Seest thou that this also brings consolation? For we are most closely attached to those earthly parents, when we see that not for any interests of their own they either command or advise us: but their earnestness is, wholly and solely, on our account. For this is genuine love, and love in reality, when we are beloved though we be of no use to him who loves us,-not that he may receive, but that he may impart. He chastens, He does everything, He uses all diligence, that we may become capable of receiving His benefits. "For they verily" (he says) "for a few days chastened us after their own pleasure, but He for our profit, that we might be partakers of His holiness." What is "of his holiness"? It is, of His purity, so as to become worthy of Him, according to our power. He earnestly desires that ye may receive, and He does all that He may give you: do ye not earnestly endeavor that ye may receive? "I said unto the Lord," one says, "Thou art my Lord, for of my good things Thou hast no need."”
