Observation: The author of Hebrews is going into an explanation of "faith", which he says at its core is the belief in things unknowable ... an assurance of hope that finds its sure conviction in things unseen. He will go into a full discussion of how the patriarchs of the Jews demonstrated their faith, however the very first example of faith is this ... we understand the universe was created by the word of God. He clarifies that this means everything we see was actually made from things are not seen.
Creation wasn't a construction project. It wasn't the act of some all-powerful being who took 'stuff' and put it together to make other stuff. Creation wasn't an observable reaction of elements colliding that someone could have observed. By faith, we know that the Lord simply created everything, and that we can now see and experience nature and everything in the universe because he simply "did" it.
The word of God - the bible - begins with creation. Creation involves the Lord speaking everything into existence, and the very word itself that he speaks took form as Jesus. Furthermore, we know that it is this very principle - creation - that is the first thing attacked by those without faith. Those without faith will declare all kinds of ideas about how creation occurred, most of which fall into the incompressible pattern of, "there was absolutely nothing ... which then blew up." They are also the ones who fail to see beauty and wonder in the created world, instead dwelling on disasters and storms and violence as examples of chaos or fear. They are also the ones who will in turn worship nature, attributing supernatural powers to everything from the sun, to crystals, to mountains, to certain creatures, as if these things have divine understanding completely independent of a divine architect.
Application: I was reminded again yesterday that, in the Old Testament, baal worship with nature worship, and that (again) we are approaching that same twisted understanding of creation in our modern society.
One of my daily prayers is thanks to the Lord for creation and nature, and our ability to appreciate it. I know this is so true, that the Lord created everything, but he also then created us with an inborn natural inclination to marvel at the wonder and beauty of creation as a means of showing himself to us. The fact so many people twist that internal emotion into some kind of false worship is beyond my comprehension.
Then again ... no, it isn't beyond my comprehension, because the author of Hebrews says why it happens. It is a lack of faith. Those without faith in the Lord cannot therefore understand creation. A proper understanding of creation and a proper placement of faith go hand-in-glove.
Prayer: Lord, as I say every day, I thank you for the created world and the nature I see all around me, and for the heart within me that sees the splendor and wonder of that creation. May I always see you and your love every time I look out a window at the trees, or wild animals, or a stormy sky, or any and all other aspects of creation, for I know they are all evidence of you, and expressions of your love for us. Amen.
