Living in Light, Love, and Truth: Walking in Light

1 John 1:5–2:2

When was the last time you had to use your cell phone as a flashlight? Maybe you were rummaging around in the garage, trying to read a menu in a dimly lit restaurant, or searching for something in the backyard at night. Why did you need it? Because it was dark—and without light, you couldn’t see clearly.

That’s a picture of life in this world. As sinners living among other sinners in a fallen world, we encounter darkness every day. Sure, we may have Instagram-worthy moments that feel like sunny-day picnics, but the truth is, life often feels more like a midnight walk through the woods. On most days, we face more confusion, temptation, and brokenness than clarity and peace.

And here’s the problem: without light, we can’t move forward safely. Without light, we can’t see where we’re going—or even where the dangers are. That’s why we need something outside ourselves to light the way. Psalm 119:105 says: “Your word is a lamp to my feet and a light to my path.” God has provided light for our darkness—truth that reveals reality and guides us forward.

It is this idea of light that John starts the main part of his teaching: “God is light, and in Him there is no darkness at all” (1 John 1:5).

God Is Light

When John says that God is light, he’s saying something profound. Light represents what is good, pure, true, beautiful, and holy. Darkness, on the other hand, represents evil, deception, and sin.

To say that God is light means:

• His character is good, pure, and beautiful.
• His word is true and trustworthy.
• He reveals the way of life.

In God there is no deception, no evil, and no sin. He is holy—and that holiness shines into our world to expose what is real.

This was not just a theological statement for John; it was practical. False teachers had infiltrated the early church. They claimed fellowship with God while living in sin. They claimed they had no sin to worry about. Some even claimed that sin didn’t matter because it only affected the body, not the spirit. John corrects these lies with the truth of who God is and what it means to walk in the light.

Three False Claims

John takes up three false claims the false teachers were making:

1. Claim: We can have fellowship with God while living in darkness. — John says no—if we walk in darkness while claiming to know God, we are deceiving ourselves. Fellowship with God is seen in how we live: walking in truth, resisting evil, and demonstrating God’s character.
2. Claim: We don’t have sin. — John says that if we deny our sin nature, we are lying to ourselves. The good news, though, is this: “If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness” (1:9).
3. Claim: We have not sinned. — This is even more dangerous. To deny sin in our lives is to call God a liar and reject His word. Scripture is clear: “All have sinned and fall short of the glory of God” (Romans 3:23).

John’s point is not that Christians will never sin. His point is that when we sin, we have an Advocate—Jesus Christ the righteous. His death on the cross atones for our sins, and not only for ours, but for the sins of the whole world.

What This Means for Us

So how does this speak into our daily lives?

1. Life makes sense through the reality of God. On our own, life often feels meaningless. Why do people do terrible things? Why do I struggle with behavior I know is wrong? Why does life sometimes feel empty? The answer is found in the light of God—through His word and through Jesus. He helps us make sense of the world and shows us how to live.
2. Living in the light is more about how we live than what we know. Right belief matters—but right belief is meant to lead to right living. There are people who can recite the creeds, quote Scripture, and defend doctrine, yet their lives are marked by pride, anger, or selfishness. Walking in the light is about demonstrating God’s character in everyday life: love, kindness, honesty, forgiveness.
3. We need humility. The danger John confronts is pride—a pride that says, “I’ve got it all figured out. I don’t struggle with sin. I don’t need correction.” Walking in the light requires humility: admitting that we still have darkness in us, that we still sin, that we still need God’s grace every day. The good news is that we don’t need to hide our sin or pretend it isn’t there. Jesus has already taken care of it.

Walking in the Light

Here’s the heart of it:

1. God is light—holy, pure, and true.
2. We cannot claim fellowship with Him and continue to walk in darkness.
3. Walking in the light means living honestly, humbly, and lovingly.
4. And when we do sin, we don’t deny it or despair over it—we bring it to Jesus, our Advocate.

This is the good news: The God who is light has made a way for us to walk in His light—through Jesus.

So let me leave you with two challenges:

• Personal: Practice walking in the light by confessing your sins honestly to God. Don’t excuse them. Don’t hide them. Bring them into His light, trusting His promise of forgiveness.
• Relational: Look for one way to demonstrate God’s character in your relationships. Be patient with someone who tests you. Show kindness when it isn’t deserved. Offer forgiveness when it’s hard.

Closing Thought

Imagine a room with every window shuttered and every light switched off. You can’t see the dust, the clutter, or the broken things. But when sunlight pours in, everything is revealed.

That’s what it means for God to be light. His light exposes our sin, but it also reveals our Savior. And that’s the hope of the gospel: Jesus, our Advocate, has already taken care of our sin.

So step into the light—live honestly, walk humbly, love deeply—and let God’s character shine through you into a dark world.
