Ver. 21. That the creature itself also shall be delivered from the bondage of corruption.
Now what is this creation? Not yourself alone, but that also which is your inferior, and partakes not of reason or sense, this too shall be a sharer in your blessings. For it shall be freed, he says, from the bondage of corruption, that is, it shall no longer be corruptible, but shall go along with the beauty given to your body; just as when this became corruptible, that became corruptible also; so now it is made incorruptible, that also shall follow it too. And to show this he proceeds. (εἰς) Into the glorious liberty of the children of God. That is, because of their liberty. For as a nurse who is bringing up a king's child, when he has come to his father's power, does herself enjoy the good things along with him, thus also is the creation, he means. You see how in all respects man takes the lead, and that it is for his sake that all things are made. See how he solaces the struggler, and shows the unspeakable love of God toward man. For why, he would say, do you fret at your temptations? you are suffering for yourself, the creation for you. Nor does he solace only, but also shows what he says to be trustworthy. For if the creation which was made entirely for you is in hope, much more oughtest thou to be, through whom the creation is to come to the enjoyment of those good things. Thus men (3 manuscripts fathers) also when a son is to appear at his coming to a dignity, clothe even the servants with a brighter garment, to the glory of the son; so will God also clothe the creature with incorruption for the glorious liberty of the children.
