John Calvin Commentary Romans 8:22

"For we know that the whole creation groaneth and travaileth in pain together until now." — Romans 8:22 (ASV)

For we know. He repeats the same sentiment, so that he might apply it to us, although what is now said has the effect and form of a conclusion. For since creatures are subject to corruption—not through their natural desire, but through the appointment of God—and since they also have a hope of being freed from corruption in the future, it therefore follows that they groan like a woman in travail until they are delivered.

But it is a most suitable analogy; it shows that the groaning of which he speaks will not be in vain or without effect, for it will eventually bring forth a joyful and blessed fruit. The meaning is that creatures are not content in their present state. Yet, they are not so distressed that they pine away without a prospect of a remedy; instead, they are, as it were, in travail, because a restoration to a better state awaits them. By saying that they groan together, he does not mean that they are united by mutual anxiety, but he joins them to us as companions. The word hitherto (or “to this day”) serves to alleviate the weariness of daily languor; for if creatures have continued for so many ages in their groaning, how inexcusable will our own weakness or laziness be if we faint during the short course of this shadowy life.
