“It shall be, when I bring a cloud over the earth, the rainbow
shall be seen in the cloud; and I will remember My covenant
which is between Me and you…” –Gen. 9:14, and 15
Chemistry is my hardest class this year; I have never done anything like it before, even biology was a piece of cake compared to chemistry. Most of the time when things like chemistry or math get really complicated I wonder, “How am I ever going to use this in life?” , but come to find out, chemistry does applies quite often to life (no pun intended).
One of the most recent chapters in my chemistry book was about light and how some kinds are visible while others are not; it is super complicated but very interesting! One of the things that really caught my attention was rainbows; how their made and why we see them, and whatnot. In the Bible, the rainbow was a reminder to mankind that God remembered the promise He’d made to Noah, that He would never destroy the earth by flood again. Yeah, as a Christian I remember that story but I have never really thought about the gravity of such a promise; and when God promises something, He always keeps faithful to it. So when I began chemistry I went in expecting just to learn about science but I instead learned something about God and life too.
The science of light is really complicated, so much so that even scientists don’t understand it completely, which means I only understand so much. But here are a couple of good things to know about light:
Wavelength determines the color of light,
- Not all light can be seen by the human eye (ozone, gamma rays, etc.),
- Amplitude is how big the wavelength is and how bright it (the wavelength) is,
- Frequency applies to the number of crests between each given point per second,
Why our eyes can’t always see light is because of the makeup of that certain kind of light; why we have sight is because our eyes have “sensors” in them. All matter is moving, even something that is standing still (please don’t ask me, I barely understand it myself). Our eyes pick up the signals being thrown off of these “objects” that are always moving, and that is why we see things! Different lights use different signals, and our eyes can’t always pick up on them. I am not quite sure how it all works, but those are some of the basics.
Now that we know a tiny bit about light, I want to talk rainbows. Rainbows belong to what is called the visible spectrum (yes, I am eventually getting to the spiritual part of this post. Bear with me!) and that is why we see them (obviously). When it rains, water is suspended in the air and the droplets act like prisms; though the light from the sun may be yellow/white, the prisms separate the one kind of wavelength (color) to create all kinds of different wavelengths (colors). That is why the rainbow has so many colors!!!
With this in mind think about a rainbow. It consists of red, orange, yellow, green, blue, indigo, and violet; red has the highest wavelength and violet has the lowest, but violet has the highest frequency of all the colors while red has the lowest. You still with me here? So, we have all the colors of the rainbow and we know that we can see a rainbow, but how do these colors ALWAYS appear in the same order when they form a rainbow? Well, God is creative. Red has a specific wavelength (color), so whenever a raindrop is suspended, it will always reflect the same as it did the day before; red has the same wavelength, so it will always be red to our eyes. It is the same for all the rainbow’s other colors. Think about all the effort God went through not only creating, but imagining the rainbow. He didn’t have to promise Noah anything, but He still did, and everything He does reflects Him. Just like the rainbow’s colors, God will be the same tomorrow.
God was the same yesterday and He’s the same today : faithful, loving, dedicated, a father, and merciful, the Creator of all. Hebrews 6:18 says that it is literally impossible for God to lie, and 2 Timothy 2:13 says that even when we are faithless, He remains faithful. Can you imagine what blessings would come if we remained faithful, how much more would He lavish upon us if we just trusted Him? Look at Noah: he trusted God with everything he had; home, family, and possessions he gave up to God to let Him do with it as He willed. Look at what he got! A rainbow, an eternal promise that is seen even to this day by all mankind. God created the rainbow as a promise to mankind, present and future, to know that He would not let a flood like that one happen ever again. Yes, He created it with mankind in mind, but Noah is the reason it exists. If it hadn’t been for his courage and faith, his obedience to God, we wouldn’t be here to witness one of the greatest wonders of the universe! That makes me think about how valuable one life can be, how the choice of one can irreversibly change the course of history forever. Noah changed the fate of the earth, Joshuah and Caleb were faithful and the only two of the first generation to see the promised land, and Christ changed the fate of man. And you and I can change the world, too, if we remain faithful to God and seek His kingdom instead of ours. One person, one choice at a time, and maybe one day we’ll have our own rainbow.
P.S. In Revelations it talks about a rainbow that is perpetually over the throne of God as a reminder of what He promised to us. Pretty cool, right?
“The rainbow shall be in the cloud, and I will look on it to remember the everlasting covenant between God and every living creature of all flesh that is on the earth.” –Gen. 9:16
