Recently, I have come across the words ‘spectrum of light’ in two different settings. When repetition happens, I take note. One instance was the Netflix show, “Brainchild.” The episode was discussing electromagnetic energy, gravity, and other forces. Lydia and I like science shows, and it put some things into perspective for me.

Electromagnetic radiation comes in frequencies or wavelengths. Visible light, or ROYGBIV, is only one part of that spectrum. Light is then absorbed by various objects and we see whatever color bounces off. Other frequencies include various radio waves and microwaves. But they all have to do with energy on the same spectrum.

Humans can only see the rainbow colors, but there are ultraviolet and infrared light waves that are invisible to us. These are just beyond the violet/purple and red wavelengths. Ultraviolet light waves are faster because they are short and close together, while infrared light waves are slow and have less energy.

Ultraviolet rays can be harmful. They can cause sunburns, for example, or damage our eyes. But they can also bring health benefits like increasing Vitamin D production.

Infrared rays are often used in night vision for surveillance or tracking wildlife (think nature shows on PBS or Nat Geo). They are also used in weather satellites. Pretty cool!

As I was watching the show with Lydia, I thought about how God designed our eyes.

Interestingly, He gave many animals greater field of vision and the ability to see more colors. Cats and dogs only see certain muted colors, but some birds and spiders can see UV rays. A chameleon can see 360 degrees (yes, a full circle!) as its eyes are near the top of its head. Its eyes can also operate independently of each other!!

This made me wonder… Why did God ‘limit’ our eyesight compared to the animals? Perhaps it was so we could have less distractions… God knows we often need help keeping our eyes focused on Him.

Or maybe it was so we wouldn’t look funny. I’m glad we don’t have bug eyes! 😉

Either way, the rainbow first appears in the Bible as a symbol of God’s faithfulness. For me, I see it as both a reminder of God’s firm promise and a reminder to trust Him.

We can’t see the future or fathom all that is going on around us. We don’t know what tomorrow holds and can’t see how things work out. We can’t fully understand or control each of those circumstances, either!

Sometimes, our limited vision poses challenges for us. We don’t always have the correct perspective. But it can also be a major blessing in that we don’t bear so much responsibility. We don’t hold the weight of the world on our shoulders.

At the same time, there are invisible spiritual forces of good and evil at war. Like many Bible characters, we would probably freak out if we saw these supernatural beings in real life (think four-faced cherubim or the beast from Revelation!).

Someday, in Heaven, we will see the full spectrum of color. We will see everything as it should be. In the meantime, we can still have peace. We can trust Jesus and thank Him for His protection. He’s got this. 

He is light, and He reigns over the darkness, too.

God, thank you for the beautiful world you have created! Thanks for letting us enjoy all the colors of the rainbow. Thanks for protecting us and providing good things for us. Help us trust You with all we cannot see. In Jesus’ Name, Amen

Questions: Have you ever used night vision? Is it easy or difficult for you to trust God when you can’t see how it all works out? (That’s called faith.) 🙂

Task: Read up about these six animals with incredible vision. God is soo cool!
