The creation’s continued existence is only possible with God’s willing it. He is not removed from matters of the universe, rather He is its life force. The creation continues to exist because God finds its continuance to be good. He observes his work after creation and as long as he is satisfied with it He wills it to continue.
Contrast that to Man. Sometimes Man can set things in motion but then finds himself over his head and losing control of what he created. (Man is never in full control. Man’s creations are actually not creations but rather reconfigurations of what already exists, thus his creations are not dependent on him to continue to exist. GS)
