In this passage, I think many complex ideas are highlighted. First, we can see the descriptions of the basic earth, where we can see that a humane relatability when reading the passage. I think this passage shows us a familiar God that we can understand at the very least, which is shown through phrases explaining how God saw that light is good. We can almost get a glimpse of the rationality of God when we observe his thought process come together to create the universe. This passage expresses the beauty of life as a whole by showing a reverse decomposition of its elements. We live day to day not noticing these components, but when we have to rebuild the life that seems normal to us, we can truly appreciate the importance of the contrast between light and darkness, for example. Moreover, God creates humans in his image. This idea is key to the possible divinity of the human soul, which is probably why God tells them to rule and prosper. Humans are the last creation that is God makes, which shows their importance. In other words, we can look at humanity as the grand finale to the creation of the world.
I think that the idea of rest could represent a twofold meaning. The seventh day could represent the greatness and importance of the world God has created. Just like a painter who has to admire the masterpiece he just finished; God takes a day to look at what he has made from nothing. God could also be using the concept of resting to signal that as of now human beings have a responsibility towards this life and some of it is out of God’s reach. To explain, if God created us a free creature then he obviously can’t decide what we choose to do.
