I know the “work” of God in creating us is finished. The work of God in creating the universe is also finished but the universe is still expanding. More universe today than yesterday so in that sense, I’d say the universe is still being created, even though God’s not “working” on it anymore.
Is man still being created also? Not in a physically evolutionary sense but in a growing Spiritual and moral sense? I think slowly but surely, in a two steps forward and one step backward kind of way, we are an improving species. We try to be more moral and screw it up a lot but over thousands of years, we make progress, which makes us different than a thousand years ago. I also think the moral/Spiritual side of man is the side that counts more than the physical side. Being different than we were a thousand years ago could mean our creation wasn’t finished back then and still isn’t finished now.
