Genesis 1:1 In the beginning, God created the heavens and the earth. 2 The earth was formless and empty. Darkness was on the surface of the deep and God’s Spirit was hovering over the surface of the waters. 3 God said, “Let there be light,” and there was light.
There is controversy over whether Genesis 1 is to be taken as a sequential account of the creation, or should be interpreted in some other way, and over when and how long creation took place. Let’s put those matters aside. They don’t really matter for the topics of this post. The first reported created act (although the creation of the earth seems to have come first) is bringing light about. That’s important.
Light is important. The main source of usable energy on earth is light. Energy from light drives the water cycle. Light is absorbed by green plants, and almost all of the food we eat exists because of that. Light makes it possible for us to perceive where we are, where we are going, and who and what is around us. Light makes it possible for us to work, and to play. Without light, reading would be difficult or impossible. Except for those unfortunates of us who are blind, we live in a world perceived and navigated because light is present.
The Bible doesn’t say “let there be an electromagnetic spectrum.” Such a term wouldn’t have made sense to the ancient Israelis, and doesn’t make sense to a lot of us today. See here for more about that spectrum. But I will say that visible light is a rather small part of a range of energy forms, ranging from gamma rays, X-rays and ultra-violet to infrared, microwaves and radio waves. The people living when Genesis was written, and when it became a part of their culture, had no way of detecting these other forms, or appreciating their importance. However, whenever and however light came to be, this whole family of energy must have accompanied it. I don’t know about you, but I use WiFi every day. I’m not sure whether my phone uses 5G or not, but, whether it does, or not, it’s using part of the electromagnetic spectrum to help me communicate.
I had a chest X-ray a few weeks ago. That part of the electromagnet spectrum allows us, as it were, to “see” parts of our bodies that we can't see with ordinary light.
We open our blinds frequently. This is partly so we can see our surroundings. It is also to help heat our home without adding to the utility bill. Light is reflected -- that’s how we see, as light is reflected off of whatever we are looking at, and comes back, going through our pupils and striking our retinas. But it is also absorbed, for example by green plants that carry on photosynthesis. Some of the absorption is manifest in that light energy is converted to heat energy, which, when radiated, is another part of the electromagnetic spectrum. Without heat derived from the sun’s light, the earth would be uninhabitably cold.
Some other Biblical thoughts about the electromagnetic spectrum. Here’s a quotation from 1 Timothy: “6:16 He alone has immortality, dwelling in unapproachable light, whom no man has seen, nor can see: to whom be honor and eternal power. Amen.” Unapproachable light? Yes, there is that, physically. We can’t be exposed to parts of the electromagnetic spectrum, in any great amount, or for any great length of time, without suffering damage, or even death. Is the scripture talking about the electromagnetic spectrum, as physicists measure it, or is this symbolic of God’s great holiness and power? Or is it both? I don’t know.
John 8:12 Again, therefore, Jesus spoke to them, saying, “I am the light of the world. [Perhaps referring to Isaiah 60:1] He who follows me will not walk in the darkness, but will have the light of life.” Christ, Himself, illuminates, warms, communicates. He is truly the light of the world. (See John 1:1-9.)
Finally, Revelation 22:4 They will see his face, and his name will be on their foreheads. 5 There will be no night, and they need no lamp light or sun light; for the Lord God will illuminate them. They will reign forever and ever. I don’t pretend to understand this, but its part of the Bible.
