Overview

Our culture keeps asking, “What do you do?” and teaches that your activity creates your identity. Jesus overturns that formula. In the Sermon on the Mount He first names who His followers already are—“salt of the earth” and “light of the world”—then simply calls us to live it out. When we remember our identity in Christ, we carry God’s presence into every space, become a beacon of hope, and no longer chase approval that can never satisfy.

Main Points

The world’s formula: Activity → Identity

• From childhood we’re asked, “What do you want to be?” but the question really means, “What will you do for a living?”
• Society measures worth by accomplishments: job titles, weekend plans, retirement plans.
• Two problems: God is missing from the equation, and no amount of doing ever feels like enough.

God’s formula: Identity in Christ → Activity

• In God’s kingdom who you are determines what you do.
• Previous weeks: “I am God’s masterpiece,” “I am an ambassador.” Today: salt and light.
• We don’t work for God’s approval; we live from it.

“You are the salt of the earth” — our identity

• Salt in Jesus’ day was valuable and useful, but more: it symbolized covenant—sprinkled on every sacrifice and still used on bread at Jewish meals.
• Jesus’ statement means, “You are My covenant people, the very reason I came.”
• Identity gift: we belong to Him before we perform for Him.

“You are the light of the world” — our purpose

• Light throughout Scripture represents God’s presence (Genesis 1:3; Revelation 21).
• Jesus (John 8) now shares His title with His followers: wherever we go, God’s goodness goes.
• City on a hill image: a visible, hope-giving community that welcomes others.

Living illustrations of light

• Story: Kevin & Janet saw the darkness of children without homes, began fostering, and now shine light into kids’ lives.
• Story: Chef Devonte reshaped a harsh kitchen culture into a place that builds people up.
• Story: Students Gabby, Gracie, and Kin host a 7 a.m. Bible study at school, taking church to classmates.

Drift comes when we forget who we are

• Illustration: The preacher’s Hanoi run—lost sight of the hotel and ended up miles from where he intended.
• When we lose identity we find ourselves in broken relationships, debt, or spiritual dryness.

Be who you already are

• Illustration: His Labrador retriever “Lady” naturally retrieves because it’s in her DNA—she just needed to be released.
• Likewise, followers of Jesus don’t need a list of tasks; we need to remember our DNA and act from it.

“I am the salt of the earth, so I will be light in the darkness and a city on the hill.”

Key Truths

• The gospel replaces “Do to become” with “You are, therefore do.”
• In Christ we are God’s covenant people—valuable, useful, and already accepted.
• Light isn’t hidden; Christians are meant to live publicly for God’s glory, not personal applause.
• Forgetting identity always leads to unintended destinations; remembering it releases purposeful action.

Response

• Anchor each morning in your God-given identity before facing tasks.
• Enter workplaces, schools, and homes expecting to carry God’s presence there.
• Refuse to chase approval from parents, bosses, or self—receive and rest in God’s approval.
• Look for darkness around you this week and intentionally shine: serve, speak hope, welcome outsiders.
• Practice generosity that points people to “your Father in heaven,” not to you.

Closing

Jesus never handed out three easy steps; He handed us a new name. When we live as salt and light, the world tastes covenant faithfulness and sees divine brightness. The invitation is not to strive harder but to display what is already true of us.

“Go be who you are—salt of the earth, light of the world, a city on a hill.”

Prayer

The pastor thanked God for doing all the work necessary for our salvation, asked the Spirit to remind believers daily of their identity, and prayed for courage to live as light in the darkness. He then led those ready to follow Jesus in a surrender prayer, celebrating their new life in God’s family.
