What Is Baptism? What Actually Happens in the Water

I've performed dozens of baptisms, and every single one has had a moment that catches me off guard. It isn't the ceremony itself, the words, the water, the family watching from the front row. It's the face of the person coming up out of the water. There's something that happens in that moment that I cannot fully explain. Some people come up weeping.

Some come up with a grin so wide it looks almost cartoonish. One elderly woman came up laughing, just laughing. With her hands in the air. She said afterward she didn't know why she was laughing. She just could not help it.

Something happens in baptism. What exactly, Christians have argued about for two thousand years. But the argument itself tells you something: this isn't a minor thing. You don't argue for centuries about things that do not matter.

The Words on the Page

Romans 6:3-5, written by Paul around 57 AD to the Roman church before his arrival there, is the most theologically dense treatment of baptism in the New Testament:

Something I've come to believe. "Or don't you know that all of us who were baptized into Christ Jesus were baptized into his death? We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life. For if we have been united with him in a death like his, we will certainly also be united with him in a resurrection like his."

Paul is writing this in the context of a question about whether Christians should keep sinning now that they are under grace. His answer is essentially: do you know what happened when you went into that water? Let me tell you what that was.

What This Actually Means for Baptism

I've sat with many people through this. The Greek word Paul uses for "baptized" is baptizo — to immerse, to plunge into, to submerge. In the ancient world it was used for dyeing cloth (to immerse it in dye until the color saturated the fabric) and for the sinking of ships. It's a total immersion word.

Paul's argument is that baptism is a physical enactment of something that has spiritually occurred. When you go under the water, you are being identified. In your own body — with the death of Jesus Christ. When you come up, you're being identified with his resurrection. The water is a grave and an exit from the grave in the same gesture.

Colossians 2:12 states it more directly:

"having been buried with him in baptism, in which you were also raised with him through your faith in the working of God, who raised him from the dead."

The burial and the resurrection happen together. You don't get only the burial — the whole point is that what comes out of the water isn't the same as what went in.

1 Peter 3:21 adds another layer:

"Baptism, which corresponds to this, now saves you, not as a removal of dirt from the body but as an appeal to God for a good conscience, through the resurrection of Jesus Christ."

The Greek word translated "appeal" — eperotema — can also mean a pledge, a solemn request, a formal declaration. Baptism is the public, physical moment where you declare: I'm staking my life on the resurrection of Jesus.

The Reading That Asks More of You

The early church understood baptism as a public, political, and sometimes dangerous act. In the Roman Empire, declaring allegiance to a crucified criminal-turned-king was not a neutral religious preference. In later centuries, during periods of persecution, being baptized could cost you your job, your family's social standing, or your life.

We have domesticated baptism. It happens in a clean church building with good lighting and family photos afterward. The early church baptized people at night, in rivers, in catacombs. The stakes were different. And that difference in stakes shaped what the act meant — not only intellectually but viscerally.

The question baptism raises. And must raise — is: has anything actually died? Is there a before and after? Or has it simply been a ritual performance of something that hasn't occurred internally? The water does not do magic. The water enacts something. If the something has not occurred, the enactment is empty. This isn't meant to frighten people — it's meant to slow them down enough to take it seriously.

Practice, Not Just Belief

1. If you have been baptized, revisit what it meant

Read Romans 6:3-5 and ask yourself: what died when I went into that water? What was the "old self" Paul talks about in verse 6? Name it specifically. Not a general category, the specific patterns, the specific identity, the specific allegiances that baptism was declaring finished. That specificity gives the event its continuing power in your life.

2. If you have not been baptized and you are a Christian, take it seriously

Baptism in the New Testament follows belief — consistently, immediately, publicly. It's not presented as optional or as something to get around to eventually. If you believe in Jesus and have never been baptized, the question is worth sitting with honestly: what is the resistance? Is it fear of public declaration? Doubt about whether the faith is real? Find out what the hesitation is and address it.

3. Use the memory of your baptism as an anchor

Martin Luther, in times of spiritual darkness and doubt, would say to himself: baptizatus sum — I've been baptized. It wasn't a magical formula. It was a return to a fixed historical fact about his identity. When shame, doubt, or spiritual attack comes, the baptism is a marker. That happened. That was real. You're the person who came out of that water.

4. Let it reshape your identity language

The early church referred to new believers as "the baptized" — it was an identity category, not just an event. If your baptism has become only a memory rather than a present reality about who you are, spend time with Colossians 3:1-4: "Since, then, you have been raised with Christ, set your hearts on things above." The resurrection of baptism is meant to be a present-tense orientation, not a past-tense footnote.

Where Prayer Begins Here

God, I stood in that water, or I will stand in it — and made the most audacious claim a human being can make: that the death and resurrection of Jesus is mine. That what happened to him happened to me. I am staking my identity on that. On days when I feel nothing, when the faith seems like a historical artifact rather than a living reality, bring me back to that water. The cold of it, the weight of it, the face I made coming up.

That happened. I'm the person who came out of that water. Hold me to that. Amen.
