Not that I count these present sufferings as the measure of that glory which is to be revealed in us. If creation is full of expectancy, that is because it is waiting for the sons of God to be made known. Created nature has been condemned to frustration; not for some deliberate fault of its own, but for the sake of him who so condemned it, with a hope to look forward to; namely, that nature in its turn will be set free from the tyranny of corruption, to share in the glorious freedom of God’s sons. The whole of nature, as we know, groans in a common travail all the while. And not only do we see that, but we ourselves do the same; we ourselves, although we have already begun to reap our spiritual harvest, groan in our hearts, waiting for that adoption which is the ransoming of our bodies from their slavery. It must be so, since our salvation is founded upon the hope of something. Hope would not be hope at all if its object were in view; how could a man still hope for something which he sees? And if we are hoping for something still unseen, then we need endurance to wait for it. Only, as before, the Spirit comes to the aid of our weakness; when we do not know what prayer to offer, to pray as we ought, the Spirit himself intercedes for us, with groans beyond all utterance: and God, who can read our hearts, knows well what the Spirit’s intent is; for indeed it is according to the mind of God that he makes intercession for the saints.
