It’s Something We Hear at Church All the Time, But What Does It Actually Mean?
“If anyone is in Christ, he is a new creation.” “There is no condemnation for those who are in Christ Jesus.”
These are phrases we hear in sermons all the time. But if someone asks, “What exactly does it mean to be in Christ?” it’s not easy to answer right away. Just going to church regularly? Living a good life? It feels like there’s something more, but it’s hard to put into words.
Today, I’d like to dig into this question a little more seriously.
Let’s Start With Air
The reason we can have a conversation right now is because of air. Sound reaches us because air transmits vibrations — that’s how words get through. If we were in a complete vacuum, no matter how loudly you shouted, nothing would reach the other person.
The Word of God works in a similar way. The same verse can deeply move one person, while another reads it and it passes by like old text. Why is that?
It’s because there needs to be something like air between me and Christ for the Word to be transmitted. That “air” is love. The Bible says:
“God is love. Whoever lives in love lives in God, and God in them.” (1 John 4:16)
For the person who knows his love and stays in it, the Word becomes a living language. But for someone who doesn’t know that love, no matter how logically it’s explained, it just sounds like meaningless noise.
So “being in Christ” ultimately comes down to this — knowing his love and staying in that love. This is the heart of union.
The Vine and the Branches — What Happens When the Union Is Broken?
Jesus used this image in John 15:
“I am the vine; you are the branches. If you remain in me and I in you, you will bear much fruit; apart from me you can do nothing.” (John 15:5)
When a branch is connected to the vine, water rises, nutrients flow, flowers bloom, and fruit is produced. But the moment a branch falls away from the vine, what happens? It just withers. It might look fine for a short while, but the lifeline is already cut.
Union is exactly this kind of relationship. When I am connected to Christ, his life flows into me. The bond of that connection is love. Staying in the relationship that love has established — that is what “being in Christ” actually means.
So What Kind of Real Change Does This Union Bring?
This is where it gets really interesting.
When a branch is connected to a tree, it shares the nature of that tree. Connected to a grapevine, it produces grapes. Connected to an apple tree, it produces apples. Not because the branch itself is remarkable, but because the tree it’s attached to is that kind of tree.
The same is true for someone united with Christ. The Bible declares:
“Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here!” (2 Corinthians 5:17)
It’s not that I’ve become something great. Change happens because the one I’m connected to is that kind of Lord. The clearing of sin, becoming a new creation, freedom from condemnation — none of this happens because I accomplished something. It all happens because I am staying in him.
So How Do I Know If I’m “In Christ”?
That’s a very practical question.
Here’s one way to think about it — has his love become real to me? Knowing in your head that “Jesus loves me” is different from feeling that love reach your heart. Paul puts it this way:
“For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.” (Romans 8:38-39)
Has this verse ever moved from your head into your heart? That moment is when the union becomes activated.
Think of it like a credit card. Just because you’ve been issued one doesn’t mean you can use it right away. You have to activate it. The credit limit and the spending power are already in the card, but without activation it’s useless. Everything accomplished in Christ — the clearing of sin, new life, freedom from condemnation — it’s all already there. The moment I receive that love with my heart, all of it begins to truly work in my life.
The Moment That Love Really Reaches You
When “being in Christ” feels too abstract, try starting here.
When I was a sinner — when I had nothing to offer, when I was actually living with my back turned to him — the Lord died for that very person that I was. Not when I was living well, but when I was at my lowest, he came for me.
The Bible says:
“But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.” (Romans 5:8)
Simply knowing this as a doctrine is completely different from receiving it with your heart. “When I was a sinner, he died for me” — the moment this reaches your chest, something changes. The instant that love touches you is the doorway into his love.
Receiving it doesn’t require a grand decision. It’s enough for your heart to be moved — “the love that died for me is real.” In that moment, you are already in him.
Union Is Not a Feeling — It’s a Relationship
There’s one misunderstanding I’d like to clear up.
“Being in Christ” doesn’t mean being in a state of emotional highs every single day. Think of a couple who have been together for a long time — their hearts don’t race the way they did when they first met. But that doesn’t mean the love is gone. If anything, they’re in a deeper place of trust and commitment.
Union with Christ is the same. It’s okay if you don’t have a moving experience every single moment. Paul said it this way:
“I have been crucified with Christ and I no longer live, but Christ lives in me.” (Galatians 2:20)
Even without a special feeling at every moment, standing on the fact that he lives in me — that is union. When you start to drift away and come back, that is how union is maintained.
So Why Does All This Matter?
The reason “in Christ” matters so much is that it tells us salvation does not depend on our own efforts or achievements.
How well I’ve lived, how much I’ve prayed, how much I’ve given — none of these can purchase salvation. Salvation is something that happens inside a relationship. When I am connected to him, what is his becomes mine.
So when faith starts to feel exhausting, it helps to come back to this question: “Am I staying in him right now?” Rather than anxiously thinking about what more I need to do, first check whether you are in that relationship.
“Come to me, all you who are weary and burdened, and I will give you rest.” (Matthew 11:28)
A branch doesn’t strain to produce fruit. It just stays connected to the vine, and fruit comes naturally. May you stay in that union today.
