John Chrysostom, on Rom 8:19

"For the earnest expectation of the creation waiteth," he says, "for the revelation of the sons of God. For the creation was made subject to vanity, not willingly, but by reason of him who hath subjected the same in hope."

And the meaning is something of this kind. The creation itself is in the midst of its pangs, waiting for and expecting these good things whereof we have just now spoken. For "earnest expectation" implies expecting intensely. And so his discourse becomes more emphatic, and he personifies this whole world as the prophets also do, when they introduce the floods clapping their hands, and little hills leaping, and mountains skipping, not that we are to fancy them alive, or ascribe any reasoning power to them, but that we may learn the greatness of the blessings, so great as to reach even to things without sense also. The very same thing they do many times also in the case of afflicting things, since they bring in the vine lamenting, and the wine too, and the mountains, and the boardings of the Temple howling, and in this case too it is that we may understand the extremity of the evils. It is then in imitation of these that the Apostle makes a living person of the creature here, and says that it groaneth and travaileth: not that he heard any groan conveyed from the earth and heaven to him, but that he might show the exceeding greatness of the good things to come; and the desire of freedom from the ills which now pervaded them.

"For the creature was made subject to vanity, not willingly, but by reason of him who hath subjected the same." What is the meaning of, "the creation was made subject to vanity?" Why that it became corruptible. For what cause, and on what account? On account of thee, O man. For since thou hast taken a body mortal and liable to suffering, the earth too hath received a curse, and brought forth thorns and thistles. But that the heaven, when it is waxen old along with the earth, is to change afterwards to a better portion hear from the Prophet in his words; "Thou, O Lord, from the beginning hast founded the earth, and the heavens are the work of Thy hands. They shall perish, but thou shalt endure; and they all shall wax old as doth a garment, and as a cloak shalt Thou fold them up, and they shall be changed." Isaiah too declares the same, when he says, "Look to the heaven above, and upon the earth beneath, for the heavens are as a firmament of smoke, and the earth shall wax old like a garment, and they that dwell therein shall perish in like manner."

Now you see in what sense the creation is "in bondage to vanity," and how it is to be freed from the ruined state. For the one says, "Thou shalt fold them up as a garment, and they shall be changed;" and Isaiah says, "and they that dwell therein shall perish in like manner," not of course meaning an utter perishing. For neither do they that dwell therein, mankind, that is, undergo such an one, but a temporary one, and through it they are changed into an incorruptible state, and so therefore will the creature be.
