Isaiah 58:6-10, Psalm 112 (111): 4-9, 1 Corinthians 2:1-5 and Matthew 5:13-16
You are Light and Salt
Last Sunday, Jesus delivered a sermon on the Mount. It is one of His most fundamental teachings – The Beatitudes. In the Beatitudes, Jesus described the character of those who belong to God’s kingdom. In today’s reading, He shifts from who they are to what they are meant to do in the world. Jesus said in today’s Gospel:
1. “You are the salt of the earth”: Salt in the ancient world was not mainly used for flavour; it was for preserving food, preventing decay, and symbolising purity. “Salt” is often linked to holiness and the preserving power of virtue. What Jesus is saying is that His followers are meant to slow moral and spiritual decay in the world. His followers (and we) should bring flavour, meaning, and goodness to human life. His followers (and we) should preserve what is true, just, and compassionate. If salt “loses its saltiness,” it becomes useless—Jesus is warning against losing one’s distinctiveness or integrity. In other words, a disciple’s life is intended to make an impact, not to be isolated. Faith is not private; it is lived in a way that alters the environment around you.
2. “You are the light of the world”
In the book of Genesis 1:3, “God commanded, ‘Let there be light.’” Light in Scripture symbolises truth, revelation, guidance, and God’s presence. “Light” is connected to the witness of good works, especially acts of charity that show God’s presence in the world. So, what is Jesus saying when he said “You are the light of the world”? He means that we, as his followers, should illuminate the darkness of the world—confusion, injustice, hopelessness. He is indicating that you and I should reveal God’s character through our actions. That is why he said in Matthew 5:16, “your light must shine before men, so that they will see the good things you do and praise your Father in heaven.” And John 8:12 makes this clear. Jesus declared, “I am the light of the world; whoever follows me will have the light of life.” Light is meant to be seen, not hidden. It is this light that enables us to carry out the corporal works of mercy highlighted in today’s reading in Isaiah 58. Our light shall break forth like the dawn (Isaiah 58:8).
Two imageries are painted here:
• A city on a hill cannot be hidden → it means Disciples of Jesus are meant to be visible examples.
• A lamp is placed on a stand → your life is meant to shine outward, not inward.
3. “Let your light shine before others…”: This is the practical application. What Jesus is calling for is: Live in a way that reflects God’s goodness. Do good works not for applause, but so people see God’s character through you. Your life becomes a signpost pointing others toward God. Jesus is not encouraging showy religion. He’s saying that authentic goodness naturally shines and draws others toward hope and truth.
The sermon on Matthew 5–7 is Jesus’ vision of what life in God’s kingdom looks like. These verses serve as a bridge:
• while the Beatitudes describe the inner character of a disciple.
• “Salt and light” describes the outward impact of that character. In other words: Who you are shapes what you contribute to the world.
🌱 Does the message of Salt and Light still matter today? Yes, they do. They are challenging us, as believers, to live with integrity in a world that often compromises. Bring hope where there is despair. Stand for justice where there is brokenness. Reflect compassion, humility, and courage.
They remind us that faith is not passive—it is active, visible, and transformative. Emphasises that Christians participate in Christ’s mission through works of mercy, justice, and sacrificial love.
Dear friends, The Church as a whole is seen as a “city on a hill,” a visible community meant to radiate Christ.
What does this mean for our lives today?
- You carry influence whether you notice it or not. Jesus did not say, “Try to be salt and light.” He says, “You are.” So, our presence changes rooms, conversations, and relationships.
- Your distinctiveness matters: Salt only works when it is different from what it touches. So, we are invited to hold onto our values. Stay honest. Be compassionate in a cynical world. Resist blending in when blending in means losing yourself.
- Your goodness is meant to be visible, not performative. Not self-promoting. But visible — the kind of goodness that quietly inspires others.
- Your life can point people toward hope, when Jesus says your light helps others, glorify your Father,” he’s saying: Your kindness, courage, and integrity can awaken something in others — a sense of possibility, meaning, or even faith.
A helpful way to think about being SALT and LIGHT is to ask yourself:
• Where can I bring preservation? (you do by protecting what is good, standing up for someone or values we should protect, keeping peace)
• Where can I bring light? (it is by offering clarity, encouragement, truth, or compassion)
• Do not hide your light. Do not cover up your values or talents?
May the Lord help us to keep our light burning brightly for all to see. Amen.
