They gathered on the hillside, drawn by reports of a remarkable teacher named Jesus. It was a diverse crowd—sitting on the ground upfront you the committed disciples, those who followed him closely. Surrounding them was the curious onlookers who were still weighing his claims, and of course there were the looky-loos - spectators hoping to witness one of his astonishing miracles. His fame had spread rapidly across Galilee and beyond; word of his authoritative teaching combined with undeniable healings pulled people from all the villages and towns in that region.
If you had stood among them that day, scanning the faces around you, certain details would have stood out. This was no gathering of the elite or the comfortable. The majority were ordinary working people—the poor and the struggling—who eked out a precarious existence from one day to the next: laborers toiling in fields, farmers wrestling with rocky soil, fishermen mending nets on the Sea of Galilee, artisans crafting goods in small workshops. Roman occupation, heavy taxes and economic pressures had left many barely hanging on, their lives marked by hardship and uncertainty.
Even more striking was the large number of the afflicted who were present. The sick pressed in close—those with chronic illnesses, the blind, the lame, the paralyzed, people tormented by demons or wracked with pain. In that era, disease often meant isolation, despair, and the assumption that God was punishing you for something you did. Yet here they were, drawn to Jesus like iron to a magnet. If you were hurting, disabled, or desperate for relief, you wanted to be near the miracle worker.
This was the make up of the motley crew surrounding Jesus when he boldly proclaimed:
You are the salt of the earth.
You are the light of the world.
His words were not being proclaimed at the opening ceremony of the Olympics surrounded by the best athletes. Or at a gathering of world leaders to discuss trade agreements. Or at a clergy conference for those who lead and teach God’s people. This gathering consisted of ordinary folks looking for hope.
You are the salt of the earth.
You are the light of the world.
Hearing those words, I imagine quite a few present shifted uncomfortably, glanced around, thought to themselves…”who, me?”
I’m nobody.
I’m just a burden on others.
I don’t matter.
He can’t be talking about me.
There were probably some who felt trapped. Their life consisted of working hard all day, keeping their heads down, paying their taxes, and being careful to do what was expected of them.
He can’t be talking about me.
Others were heart sick over their own failures. They were drawn to Jesus’ teachings about God’s Kingdom but the sin in their life weighed heavily on their shoulders.
He can’t be talking about me.
Exactly who was Jesus speaking to?
Was he just talking to his disciples and everyone else just overheard? Or was his words directed to the crowd?
Well, let’s park that to the side for a moment and turn our attention to what Jesus means when He calls His followers “the salt of the earth.”
“You are the salt of the earth, but if salt has lost its taste, how shall its saltiness be restored? It is no longer good for anything except to be thrown out and trampled under people’s feet.
In the first-century world of Galilee and Judea, salt was far more than a table seasoning—it was a vital, everyday necessity. Salt was harvested from the Dead Sea or from coastal evaporation pits, and it was precious enough that Roman soldiers were sometimes paid in salt - in fact, this is the origin of our word “salary”. Without refrigeration, people relied on salt to preserve meat and fish, preventing rot and decay. Salt kept food edible for months, even in the hot climate.
Some interpreters see this preservative quality at the heart of Jesus’ metaphor. Just as salt slows or halts the spoiling of meat, disciples are called to serve as a preserving influence in a fallen world. Moral and spiritual decay—caused by greed, injustice, hatred, idolatry—tend to spread throughout a culture if left unchecked, like rot in flesh left on a table. Yet followers of Jesus, living out His kingdom values with integrity, compassion, and truth, act as a restraining force. They slow the advance of corruption, uphold what is good and righteous, and point others toward life rather than destruction.
While this may be a part of what Jesus had in mind when he used the salt of the earth metaphor, it seems to me that taste was the primary meaning since he presents the opposite statement “but if salt has lost its taste what good is it?” In the ancient world, salt wasn’t just about keeping food from spoiling—it was the ultimate seasoning. A pinch could transform bland, ordinary fare into something vibrant, enjoyable, and deeply satisfying.
Modern science shows us why this is true - according to Google: “Salt brings out flavor by suppressing bitterness, it enhances desirable tastes like sweet and savory flavors. Salt increases the perception of other flavors, and improves aroma by making volatile compounds more accessible to your nose, making food taste more complex and fuller.”
Jesus, speaking to that hillside crowd of the weary and the wounded, calls His followers the salt of the earth in this dual sense—preservers who hold back decay, and enhancers who bring out life’s hidden goodness. Disciples aren’t meant to dominate or impose; like salt, we work subtly, permeating everyday situations with the distinctive “flavor” of God’s kingdom.
Let’s think of it this way: the world, left to itself, can taste bitter—Amen? Spend anytime on social media and you can taste it. It is marked by cynicism, division, despair, selfishness, and moral erosion. Yet whenJesus people show up—those of us who are infused with His joy, hope, gratitude, compassion, integrity, and peace—we suppress that bitterness before it takes root and deepens. We draw out the sweet and savory through acts of genuine kindness that restore dignity, forgiveness that heals wounds, truth spoken in love that cuts through lies, creativity and generosity that turn scarcity into abundance. Our presence should make ordinary moments richer, relationships deeper, and God’s ways more visible amid the mundane grind of life.
Living as salt means our lives highlight God’s “flavor”—His way of doing things—against the default settings of this world. People around us don’t just hear about God’s goodness; they taste it through how we live, love, serve, forgive, and endure. The result? Life feels fuller, more complex in the best way—layered with grace, purpose, and unexpected beauty.
So who do you think Jesus is calling the salt of the earth?
Let’s look at the other vivid image Jesus declares.
“You are the light of the world. A city set on a hill cannot be hidden. Nor do people light a lamp and put it under a basket, but on a stand, and it gives light to all in the house. In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven.
What does light do? It pierces darkness, reveals what is hidden, guides the lost, exposes truth, and brings warmth and clarity where confusion and fear once reigned. In a world shrouded in spiritual darkness—sin, despair, deception, and separation from God—light is essential for life and sight.
What I find fascinating about this declaration, You are the Light of the World, is that Jesus Himself claimed this title first and foremost. In John 8:12, Jesus declares
“I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life.”
He is the ultimate source: the radiant, divine truth of God in the flesh - He is the one who illuminates the path to eternal life, who dispels the shadows of sin and death, and reveals the Father's heart. No other light can rival Him; all true spiritual illumination flows from Christ.
Yet in the Sermon on the Mount, Jesus extends this identity to His followers: “You are the light of the world.” Not “you should become” or “try to be,” but “you are.” By virtue of belonging to Him—through faith, united with His Spirit, participating in His life—disciples reflect His light. We are not self-generated sources; we are reflectors, like the moon reflecting brilliant light from the sun.
In the first-century setting, this imagery would have been immediately understood. People relied on small clay oil lamps fueled by olive oil, with a wick that produced a modest but steady flame. A single lamp, placed on a stand or ledge, could illuminate an entire modest home, chasing away the dark of night. No one lit such a lamp only to smother it under a basket or bowl—that would defeat its purpose and waste precious oil. Likewise, a city perched on a hill, and I’m sure those listening would immediately think of Jerusalem, is visible from afar even at night; its lights served as a beacon for travelers.
Jesus’ intention is very practical here: disciples aren’t meant to hide their faith in private or shrink back from a hostile world. Concealing the light—through fear, compromise, silence, or conformity—renders it useless. Instead, we are to place it “on a stand”: live our faith openly, visibly, courageously.
How do we do this? By our good works. When our hearts are right with God, and we are serving others for the sole purpose of giving glory to God and pointing others to Him - then our light shines brightly. Our acts of mercy, justice, integrity, generosity, forgiveness, humility, and love bear witness to the transforming work of Jesus in our lives and attracts others to seek Him as well. People don’t just hear about God’s goodness; they see it reflected in how you live.
Which brings me back to the question, who was Jesus speaking to?
You are the salt of the earth.
You are the light of the world.
Was it just to the twelve disciples he had called to follow Him? Was to just to the many other disciples who had already committed to His way? Or was the message broader?
There is a phrase Jesus uses several times in the New Testament - we find it in Matthew 11:15
He who has ears to hear, let him hear.
Jesus’ words are spoken to all people, but not all people listen. He is telling the children of God who were were designed by our Creator to be. God made us from the dust of the earth, breathed into us the breath of life, and called us good. He then gave us dominion over all living things. We are the salt of the earth. We are the light of the world. But we have been deceived. We have bought into a lie that tells us that we are not good enough. That we do not matter.
Jesus tramples the lie under his foot by becoming one of us and he speaks to us words of restoration. But only those truly listening , who have ears to hear, will receive this truth.
My sheep hear my voice, and I know them, and they follow me.
In the crowd that day were those who were just curious to see what was going on, others who just wanted a miracle so they could return home without pain but had no intention of changing, there were others with critical spirits who picked apart everything they heard, but there were also those who were listening, their hearts open to receive.
I’m reminded of what John wrote in…
They are from the world; therefore they speak from the world, and the world listens to them. We are from God. Whoever knows God listens to us; whoever is not from God does not listen to us. By this we know the Spirit of truth and the spirit of error.
The question for you today is: do you have ears to hear? Are you listening?
If so, then know this.
You are the salt of the earth - not to preserve alone, but to enhance, to reveal, to make the ordinary extraordinary by letting God’s life flow through you.
You are the light of the world - Don’t hide. Don’t dim. Let your light shine—through ordinary, faithful, good works—so that in a darkened time, others may see and give glory to your Father in heaven. The world gropes for truth and hope; through you, reflecting Him, they can find it. Shine brightly; the darkness cannot overcome the light that comes from Christ.
Amen.
