In Matthew 5:13-20, we encounter Jesus speaking to ordinary people—farmers, fishermen, shepherds—and declaring something extraordinary: 'You are the salt of the earth' and 'You are the light of the world.' These aren't aspirational statements about who we might become someday; they're declarations of who we already are as disciples. Salt in biblical times represented purity, loyalty, sacrifice, and preservation. It was used in offerings to God and symbolized binding covenants when people shared meals together. We're called to be that kind of presence in the world—enhancing everything we touch, bringing out the best in others, not dominating but complementing. The key is timing and balance: knowing when to speak, when to act, when to preserve, and when to enhance. Our light isn't meant to be hidden under a bowl but placed on a lampstand to illuminate the entire house. Even when life gets hard, when faith flickers and conviction fades, we must keep shining. The world doesn't need our perfection; it needs our presence, our grace, our truth, our endurance. Whether in hospital rooms, classrooms, break rooms, or family gatherings, we're called to let our light shine so others may see our good works and glorify God. This isn't casual Christianity—it's a transformed life that takes discipleship seriously, exceeding even the righteousness of the Pharisees by living out both the law and the fulfillment Jesus brings.
Keep Your Salt and Shine Your Light: Living as Disciples in a Watching World
There's something powerful about opening a cupboard and seeing what's inside. The contents reveal what kind of meal is coming—whether it will be bland and forgettable or rich with flavor and care. A bare cupboard tells one story. But when you see salt, pepper, garlic powder, seasoned salt, and all those special spices lined up, you know something good is about to happen.
Yet even the best seasonings lose their potency when stored improperly or left unused for too long. What was meant to enhance and preserve becomes useless—bland, ineffective, fit only to be discarded.
This simple kitchen truth carries profound spiritual weight.
You Are the Salt of the Earth
In Matthew 5:13-20, Jesus makes an extraordinary declaration to ordinary people: "You are the salt of the earth." Not "you might become salt" or "try to be salt." You already are.
During biblical times, salt carried deep significance far beyond seasoning food. It was used to season grain offerings to the Lord in Leviticus. Priests threw salt on burnt offerings in Ezekiel. Salt represented loyalty and sacrifice throughout Scripture. When people shared a meal together—called "sharing salt"—it established a binding relationship. Salt was also essential for preservation, keeping food from spoiling in a world without refrigeration.
When Jesus calls His followers the salt of the earth, He's declaring that disciples are meant to be pure, loyal, willing to make sacrifices, and committed to preserving the body of Christ. Salt doesn't exist for itself—it's made to complement and enhance other things. Disciples aren't made for themselves either. They're meant to be spread throughout the world, making everything they touch better.
The Importance of Timing and Balance
Here's where it gets interesting: food tastes different depending on when you add the seasoning. Salt added during cooking creates a different result than salt sprinkled on afterward. Timing matters.
Consider a perfectly cooked steak. Sometimes the best preparation is the simplest—just the right amount of salt added at the right time brings out what's already there. The salt doesn't dominate or take over; it reveals and enhances the natural goodness.
This is our calling as disciples: to be the right amount at the right time in the right place to bring out what is already there in other people. We need wisdom to know when to speak, when to act, when to preserve, and when to enhance.
Balance is equally crucial. Salt thrown on growing crops damages the soil. Too much salt ruins a dish. We must be balanced in our inner circles and beyond them, knowing how to season without overwhelming.
In Jesus's day, people had salt blocks they would taste to check if they still had flavor. When salt lost its saltiness, it was thrown out and trampled underfoot. It had failed its purpose. We cannot afford to lose our saltiness—our ability to influence and preserve and enhance the world around us.
You Are the Light of the World
If being called salt wasn't enough, Jesus continues with another extraordinary statement: "You are the light of the world."
Again, not "you might become light" or "work hard enough and you'll shine." You already are the light, right now, by virtue of following Jesus.
In a world that constantly tries to dim us, dismiss us, and tell us we don't matter, Jesus declares: You are the light of the world. You are not an accident. You are not a mistake. You carry light within you.
And that light comes with responsibility. Jesus explains that a city on a hill cannot be hidden. People don't light a lamp only to hide it under a bowl. They put it on a stand so it gives light to everyone in the house.
Our light has a purpose: to shine, to be visible, to make a difference.
When the Light Flickers
But let's be honest—light doesn't always feel bright. Faith can flicker. Conviction can fade. We all get tired, disillusioned, distracted. Bills pile up. Jobs get stressful. Relationships get complicated.
Yet no matter what, we must keep shining.
The world is watching. We cannot stop being light just because we're tired. Jesus's words are both encouragement and warning: Don't fade. Don't hide. Don't forget who you are. Stay lit.
Don't let anyone put your light out.
You are the head and not the tail, above and not beneath. You are blessed coming in and going out. No weapon formed against you shall prosper. The One who began a good work in you will complete it.
Let your light shine—in the hospital room, in the classroom, in the break room, at family reunions, in voting booths. Shine in your grief. Shine in your hope. Shine when overlooked for that promotion. Shine when struggling to make ends meet. Shine when caring for aging parents or raising children in a world that doesn't always value them.
The flame has been lit in you. Let your light shine before others so they may see your good works and glorify God in heaven.
Fulfilling, Not Abolishing
Some might think this message of being salt and light means we can ignore everything that came before. But Jesus makes it clear: "Do not think that I have come to abolish the law or the prophets. I have not come to abolish them, but to fulfill them."
Jesus didn't come for either/or. He came for both/and.
The entire Old Testament pointed forward to the Messiah—prophesying where He would come from, what He would do, how we would recognize Him. All of it matters. Not one letter of the law would disappear until everything was accomplished.
Then Jesus raises the bar even higher: "Unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven."
The Pharisees took religious life seriously. They memorized Scripture, harmonized it with their lives, and were held up as the ideal. Jesus says we need to exceed even that level of commitment.
This isn't casual Christianity. This isn't take-it-in-on-Sunday-and-forget-it-on-Monday discipleship. This is a life transformed inside and out.
The Tree
There's a story about a young man who excelled at everything—four varsity sports, nearly straight A's—but had to hide his intelligence because his community didn't value academic achievement. When his success became known, some peers decided to jump him. They told him a girl wanted to meet him at a tree, planning to ambush him there.
But his friend discovered the plot and redirected him to a different location. Then the friend went to the tree instead—and took the beating meant for someone else.
It should have been the other young man at that tree. But his friend went in his place and bore the punishment designed for him.
Greater love has no one than this: to lay down one's life for one's friends.
We all had a punishment waiting for us—death, hell, and the grave. But Jesus went to the tree in our stead. He bore our sins in His own body on the tree so that we might die to sin and live for righteousness. By His stripes we are healed.
It should have been us on that cross. But early on the third day, He got up with all power in His hands. And that's not where the story ends—He's coming back again.
Will you be ready? Will you keep your salt? Will you shine your light?
The world is watching. Keep shining.
