Light is basic to our existence. Light is incredibly complex. Light makes no sense!
We are so accustomed to light that I don't think we often take time to really ponder it's existence. Seriously, when was the last time you sat around thinking, "Wow...light is amazing! I wonder what its properties are..." Until I sat down to write about it this week, I honestly hadn't given it much thought since a high school science class I had in 1991. Ahem. That was a few years ago!
After all, light is so basic to our existence, we wake up to it, we flip on switches and have it at our beck and call, we end our day as the main light disappears and many smaller lights appear in the night sky, and rarely do we ever not have it. Little lights flash all night in our homes, and we cary light producing devices in our pockets when we have to get up and stumble out of bed unexpectedly. Light is everywhere.
But it's almost humorous to read what we know, and even more, what we really don't know about light! Just do a google search and you'll see that as basic as light is to our existence, we still seem to struggle to define all of its scientific properties and to be able to properly explain why it behaves the way it does. Sure, we can explain reflection, refraction, and the insane speed at which light travels, but when we start getting down to what light really is...things get much less uncertain.
I'm not a science geek, but I enjoy learning about these things, especially when these things collide with biblical truth. And one of the coolest things that we do know about light is this: unless it hits an object and is reflected toward something else, it continues on forever. So in space, light travels millions and billions of miles so that stars, light years away from earth, are visible to the naked eye. Even distances of darkness that are truly beyond our comprehension, cannot stop a single beam of light from reaching earth.
In the words of John: "The light shines in the darkness, and the darkness has not overcome it."
It is no accident that Scriptures often refer to Jesus as the Light of the World, and that we are instructed to "shine our lights" like Him. The power of light to penetrate the darkness (scientifically) is nothing compared to the power of light to penetrate the darkness (spiritually) in the world around us.
Let me encourage you to shine bright this week. Serve your bosses or your employees with the grace and goodness of the Lord, and let them know you are actually serving Christ in all you do (Colossians 3:17). Love your children and/or spouse this week the way Jesus would, and let them know you are really loving Him (Ephesians 5). When we live like this, our light (which is mere a reflection of the light of Christ!) penetrates the darkness and then the words of Matthew 5 ring true, "Let your light shine before others, that they may see your good deeds and glorify your Father in heaven."
