I don't doubt for a minute that all of God's creation is groaning for mankind's redemption.
My point is that such groaning doesn't mean that the entire universe fell when man fell...but that since God's Love and Spirit is infused into the universe He created, the universe (including the angelic hosts) groans with Him at man's fallen nature just as it did rejoice with Him at the Cross and will rejoice with Him at our resurrection.
If I am incorrect, I hope someone will set me straight!
I don’t know that either side can be absolutely emphatic.
It just seems to me that the nature of the wording involves the pollution and then redemption/resurrection/renewal of the whole cosmos.
That’s what I understand the original Greek implies, if not makes plain.
