Can’t Live Without It

Think about something you cannot do without. Since guessing games are not my favorite thing, let’s skip my list of things you thought of and get to the point. Did you think of light? We can’t live without it. An eclipse of the sun may grant us more understanding of the life-sustaining importance of light.

What is light? Yes, it comes from the sun. Perhaps the definition of light will help. Light is: Electromagnetic radiation that has a wavelength in the range from about 4,000 (violet) to about 7,700 (red) angstroms and may be perceived by the normal unaided human eye. Ok, that is way more than most humans would even consider thinking about light. But in this definition, we find the spectrum of light. In between the colors of red and violet are orange, yellow, green, cyan, and blue. 7 colors in visible white light. Sure, there is a physical explanation for white light having color, but the mystery of this is also fascinating. Why are there 7 distinct colors in white light?

The benefits of light are many. Solar energy, actually 8.5 minutes old when it gets to earth, can be used to create electricity. Solar energy makes the salad you will eat at your next meal. It is light that drives the worldwide process of photosynthesis. Thirsty? Our next drink of water comes from an unceasing process called the water cycle. It is driven by solar energy, or light. Without light, your next breath would be difficult, and given time, impossible. Light which drives photosynthesis also produces a side product: oxygen.

There is another aspect to light. Good light makes better photographs. Earlier this week my photos were taken in the bright light of midmorning.  It is ok to remind me that the “golden hours” for best photos are the first hour after sunrise and the last hour before sunset. The photos shared in this blog were taken in the evening golden hour. It truly does make a difference.DSC_0066_599sig

There is much more about light, you’ve thought of some by now. But we are now both at the point where we can agree one of the things we cannot do without is light, or to be technical, electromagnetic radiation.

There is another kind of light, not from the sun. The Creator of the sun spoke of this other light. While on earth Jesus said to the people who were with him, “I am the light of the world. If you follow me, you won’t have to walk in darkness, because you will have the light that leads to life.” (John 8:12) If we are candid with ourselves we know that there are two aspects to life, the physical and the spiritual. Jesus is the Creator of light, the sun. The Bible tells us Jesus was with God at the creation of the universe. John 1:2 tells us Jesus existed in the beginning with God.

As we must have the physical light of the sun on earth, we cannot live our spiritual lives without the spiritual light of Jesus. Did you read what Jesus said after declaring he was the light of the world? We “won’t have to walk in darkness, because (we) will have the light that leads to life.”

It is hard to walk in darkness. Physical darkness causes us to stumble, possibly be injured. Spiritual darkness does the same for our eternal souls. The light of Jesus leads to life. You and I cannot live without it.

What does a grandfather, husband, former public school teacher and Education Specialist for the United States Fish and Wildlife Service with many life experiences in nature do with them? A naturalist with a camera-makes outside a daily destination. My confidence is that God will guide my words, and photos. We live in a magnificent world, come and look at it with me through eyes, lens and words. To God be the glory. Current Profile Photo- Prickly Ash, the name summarizes this brushy undergrowth well. It fascinates me with its thorny branches. Seeing a vine wrapped around the trunk called for a photo.
