Communion with Christ: The Union That Changes Your Life

You can know Jesus without being in communion with him. You can have a Bible at home, a cross around your neck, show up at church every Sunday, and still keep the Lord at arm's length. In 1 John 1, the apostle John, the last of the twelve eyewitnesses of Jesus, doesn't recount the wedding at Cana, the transfiguration, or the five loaves and two fish. He speaks about one thing only: fellowship with the Father and with the Son. Because that is the heart of everything. Without close communion with Christ, there is no true life, no true light, and no true truth.

1. Communion isn't just knowing Jesus, it's becoming one with him

The word "fellowship" appears four times in 1 John 1. It isn't a churchy word: it's a word of union. To be in communion with Jesus is to be fused with him. To become one. As Paul puts it: "It is no longer I who live, but Christ living in me." You can't claim to live through Jesus if he isn't living in you.

The word "fellowship" literally means "having in common." Does your life have anything in common with the life of Jesus Christ? When you're in communion with the Son, you're also in communion with other believers, and you share: one common faith, one common grace, one common destination, one common Spirit, common gifts, and even a common enemy.

Knowing about him isn't enough. Owning a Bible isn't enough. Showing up at church isn't enough. The real question is: are you truly in communion with him, to the point where your life and his are no longer two, but one?

2. Life through communion: the logos that produces zoe

John writes: "The life was revealed, and we have seen... we declare to you the eternal life which was with the Father." He's talking about the word of life. In Greek, this isn't just any word: it's the logos. And the life he's describing isn't mere existence: it's zoe. Eternal life, abundant life, the spiritual life that only the Lord can give.

When God created Adam, he breathed into his nostrils and life entered him. That same God can breathe into your life today. When the Word of God is preached, life begins to be formed. Maybe today you're physically alive but spiritually dead. You can't be spiritually alive if the logos, the Word of God, isn't living in you.

You don't need to understand everything for the Word to nourish you. Even when you read through Chronicles and its long genealogies, the logos of life is still coming into you. A seed is being planted that will one day sprout. It's the Word that produces zoe, that produces life in abundance and life eternal.

And John adds: "We write these things so that our joy may be complete." Joy isn't separate from communion. It's the fruit of it. But be careful: this joy first passes through the tears of repentance. You can't know the joy of the Lord if you haven't first knelt before the cross and said, "I have sinned against heaven and against you. Forgive me." It's because you've repented that you can then burst into joy.

3. Light through communion: leaving your shadowed corners

"This is the message which we have heard from him and announce to you, that God is light, and in him is no darkness at all" (1 John 1:5). Not a shadow. Not a dark corner. In the Lord Jesus Christ, there is only light.

"If we say that we have fellowship with him and walk in the darkness, we lie" (v. 6). Darkness and light don't coexist. It's impossible to live in sin and be in communion with Christ at the same time. Those who have tried to hold onto their darkness have ended up growing distant even from themselves, because the light of Christ is so disruptive precisely because it wants to drive out every trace of darkness.

The question becomes very concrete: what are you willing to let go of for the Lord? Is there a "secret garden" where you refuse to let the light in? We all have shadowed corners. But the right prayer is: "Lord, come shine light even on what I don't know about myself. Come shine light even on my hidden places."

Don't believe the lie that says, "God loves me as I am, so it doesn't matter what I do." Of course God loves you as you are. But he wants to change you so you become like him. If sin weren't so serious, Jesus wouldn't have given his life for it. He wouldn't have let his hands and feet be pierced for nothing. It's precisely because sin leads to eternal death that Christ went and paid the price on the cross, 2000 years ago.

And here's where many get it wrong: "the blood of Jesus, his Son, cleanses us from all sin" (v. 7), but only the sin you actually bring into the light. Sanctification doesn't depend on how serious your sins are, or how many years you've spent living in them. It depends on what you're willing to hand over to the Lord.

4. Truth through communion: confess or conceal

"If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness" (1 John 1:8-9).

There are only two options: confess or conceal. You could walk out tonight with your sin tucked away in your pocket. No one will see it. You'll smile, eat, sleep. But your sin will still be there, because you've only hidden it. It's no big deal to hide your sin from people. What's serious is trying to hide it from God, who already sees everything, even the things you've forgotten.

It's better to be the worst of sinners who comes to repent than the best of men who refuses to. Because the best of men, the one who never asks God for forgiveness, is condemned. But the worst of men who bends the knee and asks for forgiveness is saved. That's not fair: it's called grace.

Confession only happens in truth. God's forgiveness only comes after a moment of truth between you, the creature, and him, the Creator. A moment where you simply say: "What I did was serious, and I'm asking for your forgiveness."

Then God takes the book of your life, and one by one he tears out the stained pages, the ones where you fell, the ones you're not proud of. He may keep fewer of them than you think. That's fine. There's an eternity of new pages left to write with him.

5. Tonight, you can move from darkness into light

Tonight, you can move from death to life. From a lost sinner to a co-heir with Christ. The greatest promotion in the history of humanity. Like the prodigal son, you can return to the Father. He is waiting for you. He already has his pen ready to write your name in the book of life.

And once that communion is established, your happiness will no longer depend on your circumstances. The world is happy based on what it has: the restaurant, the vacation, the car, the job. The Christian, on the other hand, is happy based on who he has. And that one never changes, never wavers, never gets lost. Even on hard nights, you can wake up and say, "He's still here." Jesus never promised a life without trouble. He promised: "Be of good cheer, I have overcome the world."

So tonight, don't leave the way you came in. Confess. Let the light in. Enter into communion. And live.

Personal Application

• Am I truly in communion with Christ, or am I settling for knowing him from a distance?
• What is the shadowed corner of my life that I'm still refusing to let God's light shine on?
• What sin am I hiding, from myself or from God, instead of confessing it?
• Does my joy depend on my circumstances, or on the presence of Christ in me?

FAQ

What's the difference between knowing Jesus and being in communion with him?

Knowing Jesus means having information about him: his life, his words, his miracles. Being in communion with him means living united to him, to the point where his life and yours become one. That's what Paul describes in Galatians 2:20: "It is no longer I who live, but Christ living in me." Many people own a Bible, wear a cross, show up at church, and still remain spiritually distant. Communion is union: sharing everything with Jesus, his faith, his grace, his Spirit, his mission.

What are the logos and the zoe that John talks about?

The Greek word logos refers to God's living, creative word, not mere printed letters, but a word that acts and produces life. The word zoe refers to the life that only God can give: eternal, abundant, spiritual life, as opposed to mere biological existence. When God's word (logos) is received into a heart, it produces God's life (zoe) in it. Even if you don't understand everything you read in the Bible, the Word is still working in you.

How can I know if I'm really walking in the light?

Three simple markers drawn from 1 John 1. First, you don't claim to be without sin: you acknowledge your faults. Second, you confess your sins to God, rather than hiding them. Third, you don't deliberately keep a "secret garden" shut off from the light of Christ. The mark of a believer walking in the light isn't perfection: it's transparency before God and a refusal to make peace with sin.
