John Chrysostom
For this very reason the Apostle says, “Furthermore, if we had our fathers according to the flesh as chasteners and respected them, shall we not much more be subject to the Father of spirits and live?”
Again he derives encouragement from their own sufferings, which they themselves had endured. As he said there, “Remember your former days,” so here he says, “God deals with you as with sons.” You cannot say that you are unable to bear it. Besides, “the Lord chastens whom He loves.”
If children obey fleshly parents, how will you not obey the heavenly Father? “Furthermore,” he says, “if we had our fathers according to the flesh as chasteners and respected them, shall we not much more be subject to the Father of spirits and live?”
He says “Father of spirits,” meaning either spiritual gifts, or prayers, or the incorporeal Powers. If with such a disposition of spirit we die, then we shall also receive life.
