Sermon on the Mount: Salt and Light (Matthew 5:13–16)

“You are the salt of the earth; but if the salt has become tasteless, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled underfoot by people.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 the lampstand, and it gives light to all who are in the house. Your light must shine before people in such a way that they may see your good works, and glorify your Father who is in heaven.”

Jesus calls His followers salt and light. Both images are powerful:

  • Salt preserves and flavors. In a world prone to moral decay and spiritual emptiness, we are called to preserve God’s truth and live in a way that adds goodness and hope. When salt loses its taste, it becomes useless—so too does a believer who blends into the world instead of influencing it.
  • Light shines in darkness. Light reveals, guides, and brings life. Jesus said, “You are the light of the world.” This isn’t optional; it’s our identity. We are meant to live openly for Christ, reflecting His character in our actions and attitudes. Hiding our light—out of fear or compromise—denies the purpose for which we were called.

Our good works are not for self-promotion but to point others to God’s glory. When people see love, humility, and righteousness in us, they are drawn to the Father who is in heaven.

Why It Matters

The world needs authentic believers who live out their faith with integrity and courage. When we lose our distinctiveness as salt, or hide our light, the culture around us grows darker and more decayed. But when we live as Jesus calls us to—preserving truth, extending grace, and shining brightly—we influence lives for eternity. Every conversation, act of kindness, and decision to stand for righteousness becomes a testimony that draws others closer to Christ.

A Prayer for Today

Lord Jesus, thank You for calling me to be salt and light in this world. Help me to live with purpose, preserving Your truth and showing Your love. Keep me from losing my “saltiness” through compromise or fear. Give me courage to shine Your light boldly so others may see and glorify You. Amen.

Questions to Guide Your Reflection

  1. What does being “salt” mean in your workplace, school, or home?
  2. Are there areas where you’ve been hiding your light? How can you change that this week?
  3. How can your good works point others to glorify God instead of yourself?
