The prophets often do the same when depicting something sorrowful. Then the vineyard weeps, and wine, mountains, and the vaults of temples howl. By this they express the excess of evils. So the Apostle, imitating the prophets, personifies creation here and says that it groans and labors. He does this not because he actually heard the groans of earth or heaven, but to express the abundance of future blessings and the desire to be freed from present evils.'
The Apostle begins to indicate the participation of all creation in the restoration of fallen man, which is to be revealed in glory in the age to come. The restoration is already acting inwardly. In the age to come it will also appear outwardly. Now it is not revealed in its brightness, because that brightness cannot be contained by the present state of things. But then the present state of creatures will be changed and adapted to the bright condition of restored and renewed human nature.
Creation awaits this revelation in the glory of the renewed and restored children of God, because its own restoration and renewal are joined to this. It does not simply await this revelation in order merely to look upon it, but because it itself will participate in that glory. By this the greatness of future glorification with Christ is also depicted. It is shown to be so great and radiant that all creation strains toward it.
'Do you not see,' says the Apostle, as it were, 'heaven, earth, sea, air, sun, moon, all visible creation, and, beyond this, the invisible creatures, Angels, Archangels, Powers, Authorities, and Dominions? All this awaits our manifestation in perfection and glory' (blessed Theodoret).
The participation of all creation in this glorification is also depicted through its participation in the restoring power of Christ. Oecumenius writes: 'Creation itself waits impatiently for our future glory. Why? Because, having been created incorruptible, it became corruptible because of human sins. For we also became corruptible from being incorruptible. Thus creation desires that men enter again into their incorruption, so that it too may receive its incorruption. For when man, through whom it became corruptible, receives incorruption, then it also will receive together with him the incorruption proper to it.'
At this point the thought comes that, just as the glory of the children of God will be revealed then, though it is being built even now, so also creation will then appear in glory. This glory is being invisibly built in it even now. The future glorious condition of all visible creation is being invisibly built even now by the providential actions of God's almighty power. Then it will be revealed and become visible.
