Don’t Make Light of the Confusing Meanings of ‘Light’

While visitors from other countries were spending time in the United States for FIFA World Cup soccer and raving about many aspects of American life, I wonder what they thought about our language. We might not realize it, but American English can be difficult to learn and comprehend. 

Take a simple example: the word “light.” If you want to pin it down to just one meaning, good luck. We have light beer and light butter, meaning fewer calories than the regular varieties. We might opt for a light snack or a light meal – something to appease hunger pangs but not enough to stuff our stomachs.

 

Some of us like to engage in light humor, which probably won’t provoke a belly laugh but might prompt at least a smile and a chuckle. I’ve long been a fan of light classical music – it’s not as lengthy and complex, and more geared for easy listening.

 

We’re careful not to make light of some topics, meaning they should be treated with proper respect and seriousness. Then we have light moments, when we’re not as serious. At times we’re asked to perform light duty, meaning tasks that won’t require a lot of time and energy. There are even more ways for “lighting” up our vocabulary, but can you see why a foreigner could get confused by our everyday jargon?

 

There’s also the most common and important use for the word light: That which refers to things like celestial orbs, light bulbs, flashlights and chandeliers. Even then, the light we find in nature has at least three intrinsic properties: Luminiferous, which means to illuminate, produce, yield or transmit light; actinic, which causes chemical changes, like photosynthesis; and calorific, which involves the production of heat or energy.

 

Light also carries great spiritual significance. It plays a starring role at the start of the Creation account. After noting, “the earth was formless and empty, darkness was over the surface of the deep,” Genesis 1:3-5 tells us light was the first item on God’s to-do list. “And God said, ‘Let there be light,’ and there was light. God saw that the light was good, and He separated the light from the darkness.”

 

What would be the point of everything else He planned to do without light by which to see it? The passage explains God commanded, “Let there be lights in the expanse of the sky to separate the day from the night, and let them serve as signs to mark seasons and days and years, and let them be lights in the expanse of the sky to give light on the earth” (Genesis 1:14-15). This is speaking, of course, about the sun, moon and stars.

 

As impressive as that was, biblical teaching about God and light was just beginning. The gospel of John opens by revisiting the Creation, declaring the preincarnate Christ was very much involved in it:

“In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through Him all things were made; without Him nothing was made that has been made. In Him was life, and that life was the light of men. The light shines in the darkness, but the darkness has not understood it” (John 1:1-4)

 

Jesus didn’t shy away from being compared to light. Speaking to a crowd in the temple courts that included teachers of the Jewish law and Pharisees, He underscored the concept: “When Jesus spoke again to the people, He said, ‘I am the light of the world. Whoever follows Me will never walk in darkness, but will have the light of life’” (John 8:12).

 

Later Jesus used a man who had been born blind as an object lesson while preparing to heal the person of his blindness. He told His disciples, “While I am in the world, I am the light of the world” (John 9:5). He came to bring light, physically and spiritually.

 

Have you ever gotten up in the middle of the night in an unfamiliar room, perhaps in a hotel or the home of a friend, and tried to negotiate your way to the bathroom in the dark? An obvious solution is to turn on a light. Instantly the darkness is dispelled, and you can see the way clearly. In a far more profound way, sin and rebellion against God have plunged the world into spiritual darkness. Jesus, in declaring He is “the light of the world,” is the only remedy for this universal problem.

 

He knew His physical presence on earth was temporary. Forty days after His resurrection from the dead, Jesus ascended to heaven. In his stead, He left what we might call His “light brigade.” Speaking to a huge crowd during His Sermon on the Mount, Jesus announced to His followers, “You are the light of the world. A city on a hill cannot be hidden. Neither do people light a lamp and put it under a bowl. Instead they put it on its stand, and it gives light to everyone in the house. In the same way, let your light shine before men, that they may see your good deeds and praise your Father in heaven” (Matthew 5:14-16).

 

We aren’t The Light, but through our lives – our actions, words, the way we conduct our lives – we can be used by God to bring His light into our world filled with the darkness of unbelief, evil and hopelessness. As the apostle Paul wrote to Christ followers in ancient Corinth, a city notorious for its pagan practices: 

“The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel of the glory of Christ, who is the image of God…. For God, who said, ‘Let light shine out of darkness,’ made His light shine in our hearts to give us the light of the knowledge of the glory of God in the face of Christ” (2 Corinthians 4:4-6).

 

When Jesus ascended to heaven, He didn’t abandon us; He gave the Holy Spirit, who abides in every believer. Only in that way could “the Light of the World” pass along the responsibility for us to represent Him as “the light of the world.” We can’t create the Light – but like moons, we can reflect it!
