What Does It Mean to Walk in the Light When You Still Sin?

By Pastor John Erickson

Have you ever walked into a dark room and tried to find something?

You know where it ought to be. You think you remember where the furniture is. So you start moving carefully, hands stretched out, hoping you don't introduce your shin to the coffee table.

Then somebody turns on the light.

All of a sudden you can see what's actually there.

John uses that picture to say something profoundly important about our relationship with God. In 1 John 1:5, he says God is light, and in him there is no darkness at all.

That sounds beautiful. It also creates a bit of a problem for those of us who follow Jesus and still struggle with sin.

How can imperfect people live in the light of a holy God?

The Light Reveals What's Real

Light does something darkness can't: it tells the truth about a room.

If your house is a mess, turning off the lights doesn't clean it. It just makes the mess harder to see. You can convince yourself the floor is clear right up until you step on a toy.

Sometimes we approach our spiritual lives the same way. We hide things. We avoid questions. We make excuses for attitudes or habits we know aren't right.

And when somebody gets too close, we get defensive.

John says if we claim to have fellowship with God while walking in darkness, we're not telling the truth. That doesn't mean we're required to become perfect overnight. He makes that clear just a few verses later.

It means the relationship God invites us into is a truthful one.

Walking in the Light Doesn't Mean Pretending You're Perfect

Here's the tension John creates in 1 John 1:8-10.

He says if we claim to be without sin, we deceive ourselves. Then he says if we confess our sins, God is faithful and just to forgive us and cleanse us.

Read that carefully.

John isn't telling Christians, "If you ever sin again, you're back in darkness and there's no hope for you." He's saying that people who belong to the light must stop pretending they don't need forgiveness.

There is a difference between struggling with sin and hiding it. One opens a person toward grace. The other builds a wall around the problem.

I love how direct John is. He doesn't say, "Well, you're probably doing fine. Just think positively." He tells us the truth about ourselves and the truth about God's mercy.

We need both.

Confession Means Agreeing With God

John's word for confess points us toward open acknowledgment. We stop denying what is true and agree with God about our sin.

In other words, confession isn't about constructing a religious speech impressive enough to persuade God that we're sorry.

It's agreeing with God about what's already true.

If another driver cuts me off on the freeway, I can decide they are the worst person who has ever existed. If I do it, suddenly I have an excellent explanation: I made a mistake; I have a lot on my mind. Funny how generous I can be with the interpretation when I am the one who needs it.

That double standard is exactly what honesty brings into the light.

When I've been selfish, I call it selfishness. When I have hurt someone, I don't rename it "having a bad day" and hope that makes it disappear. When I need to ask for forgiveness, I stop rehearsing all the reasons my behavior was understandable.

I call the thing what it is.

That can be uncomfortable. But there's a kind of freedom that comes from no longer needing to protect an image of yourself.

Why We Need Other People

Remember the bigger context of 1 John. John is writing to a community that has experienced division.

He doesn't imagine a life of truth that's entirely private. He connects walking in the light with fellowship with one another.

That doesn't mean you should announce every private struggle to a room full of strangers. Wisdom and healthy boundaries matter. But it does mean we need relationships where we don't have to pretend.

A trusted friend. A wise mentor. Someone who can listen without making excuses for you or deciding you are beyond grace.

If we only ever present the polished version of ourselves, people may admire us. But they can't really know us.

And a spiritual life built around keeping up appearances is exhausting.

God Isn't Shocked By Your Mess

Sometimes people avoid prayer because they're convinced God must be disappointed with them.

They know what's wrong. They assume the next step is to clean everything up before coming back to him.

But 1 John gives us another direction. Come into the light. Tell the truth. Receive forgiveness. Let God continue his work in you.

Jesus isn't standing in the doorway, surprised at what he discovered. He already knows.

The invitation is not to become good enough to be honest. It's to be honest so you can receive the transforming grace of God.

And if you've spent years keeping something hidden, start small. Tell God the truth in prayer. Consider whether there's a trusted person you need to talk to. If you've harmed someone, take responsibility and seek to make things right.

You don't have to pretend the darkness isn't there. That's the whole point of turning on the light.

God is light. And his light isn't merely there to expose us. It's there to lead us toward life.
