GROUP DISCUSSION GUIDE - “Do I Need to Be Rebaptized?" Acts 2:38 · Romans 6:3–4 · Mark 16:16 · Acts 19:1–5 · 1 John 5:13

Ice Breaker: Have you ever done something the right way after doing it wrong first — and realized the difference mattered? What changed?

BEFORE YOU BEGIN—A WORD ON THE TITLE 

The sermon was careful to say this upfront, and it's worth saying it here too: a person only needs to be baptized one time—scripturally. When we talk about being "rebaptized," we're talking about a first baptism that wasn't valid to begin with. The question this lesson asks isn't meant to create doubt where there is none. It's meant to bring peace where there isn't any—and to help us understand what the New Testament actually requires.

Memory Verse: "These things I have written unto you who believe in the name of the Son of God, that you may know that you have eternal life." — 1 John 5:13

KEY POINTS FROM THE SERMON 
* Some things do NOT invalidate a baptism—including verbal formulas and the character of the person who performed it
* A person can't be taught wrong and baptized right
* Baptism must be by immersion, for the remission of sins, with proper understanding
* Six categories of people need to be properly baptized (see Part 2)
* Acts 19 teaches a principle—proper understanding at the time of baptism—even though the specific situation doesn't apply to us today
* Christians should be able to know they are saved—not wonder about it

PART 1—WHAT DOES AND DOESN'T MATTER 

Read Acts 2:38 and Romans 6:3–4 before discussing.

The sermon opened with a story about a Catholic priest who performed thousands of baptisms using "we baptize you" instead of "I baptize you"—and the diocese declared every single one of them invalid. The sermon used that story to make a different point: the Bible gives us no verbal formula for baptism. The wording isn't what makes it valid or invalid.

Question 1: What does the Bible say actually matters in baptism? Based on the sermon and these Scriptures, what are the things that cannot be missing for a baptism to be scriptural?

Question 2: The sermon also said that the character or standing of the person who baptized you has no bearing on whether your baptism was valid. Why is this important? What would it mean for a person's assurance of salvation if the opposite were true?

Question 3: Why do you think so many churches place so much weight on things the Bible never requires—a specific verbal formula, who performs the baptism, etc.—while missing the things the Bible clearly does require?

PART 2 — SIX CATEGORIES: WHO NEEDS TO BE PROPERLY BAPTIZED

Read Mark 16:16 and Acts 8:35–38 before discussing.

The sermon listed six categories of people who need to be properly baptized. Review them together:
1. Baptized for the wrong reason (peer pressure, to date or marry someone, social belonging)
2. Baptized without proper understanding of the gospel
3. Baptized in a denomination—where the almost universal teaching is that you're saved first, baptized later
4. Baptized as a baby—before belief, repentance, or confession were possible
5. Not immersed—sprinkled or poured rather than buried in water
6. Living with serious, ongoing doubts about whether the baptism was legitimate

Question 4: The sermon said one of the clearest signs of an invalid baptism is believing you were already saved before you went into the water. Why would that understanding make the baptism itself meaningless? What was the person actually doing if they didn't believe the baptism was saving them?

Question 5: The sermon used this illustration: if you offered someone $100 to say "I believe Jesus is the Son of God" and they said it just for the money—without knowing what it meant—would it do them any good? Apply that to baptism. What is the difference between going through the motions and actually obeying the gospel?

Question 6: The sermon made a pointed statement: virtually all denominations teach that a person is saved first and baptized later. If that's what someone believed when they were baptized, what did their baptism mean to them at the time? And why does that matter?

Question 7: Of the six categories, which one do you think is most misunderstood—even among members of the Lord's church? Why?

PART 3 — ACTS 19 AND THE PRINCIPLE IT TEACHES

Read Acts 19:1–5 before discussing.

The people Paul encountered in Ephesus had been baptized under John's baptism—not because they were malicious or dishonest, but because that's what Apollos had been teaching before Priscilla and Aquila corrected him. John's baptism had been obsolete for twenty years. They were sincere. They were immersed. And they still needed to be baptized again—because they didn't have the right understanding at the time.

Question 8: What does Acts 19 teach us about sincerity? Can a person be genuinely sincere about his baptism and still need to do it again? What is the difference between sincerity and scriptural validity?

Question 9: Don pointed out that the example from Acts 19 doesn't directly apply to us today—but it teaches a principle. What is that principle, and where do you see it at work in the other five categories from Part 2?

PART 4—THE PERSONAL QUESTIONS

Read 1 John 5:13 before discussing. Read it slowly.

The sermon closed with something worth sitting with: Don himself went back and was baptized again—years later—because doubts about his childhood baptism were eating at him. He said his father-in-law baptized him and it gave him peace. And then he said this: wondering about your baptism is a miserable way to live.

John didn't write 1 John 5:13 so that Christians would spend their lives hoping they were saved. He wrote it so they could know.

Question 10: Do you know? Not hope, not assume—know. When you think about your own baptism, is there peace there, or is there something that has nagged at you?

Question 11: If someone you loved came to you and said, "I think my baptism might not have been right, but I don't want to do it again because I'm afraid of what it would mean about all these years in between"—what would you say to them? What Scriptures would you use?

Question 12: The sermon said: if the first one was legitimate and you do it again, you just got wet—and you have peace. If it wasn't legitimate, this one makes all the difference. What is actually at stake in that statement? And what would hold a person back from acting on it?

THIS WEEK'S CHALLENGE

Read through the baptism accounts in Acts this week—chapters 2, 8, 10, 16, and 22. In each one, note what the person understood, why they were baptized, and what happened immediately after. Come ready to share one thing that stood out to you.

CLOSING DISCUSSION 

Final Question: The goal of this lesson isn't to create doubt—it's to provide clarity. What is one thing from this study that gave you greater confidence in your own salvation, or greater compassion for someone who may need to hear this truth?

Closing Prayer—Pray for:
* Those who may be carrying unresolved doubts about their baptism
* Courage to study honestly and act on what Scripture requires
* Wisdom to speak this truth lovingly to people we care about
* Peace—the kind that comes from knowing, not just hoping

KEY SCRIPTURES FOR FURTHER STUDY

Acts 2:38—Baptism for the remission of sins Mark 16:16—Belief and baptism Romans 6:3–4—Baptism as burial and resurrection Galatians 3:27—Baptized into Christ 1 Peter 3:21—Baptism saves Acts 22:16—Wash away your sins, calling on His name Acts 8:26–39—The Ethiopian eunuch—belief before baptism 1 John 5:13—That you may know you have eternal life Ezekiel 18:20—The soul that sins shall die—not inherited sin 1 Corinthians 12:13—Baptized into one body

LEADER NOTES
This topic can bring real conviction—and real emotion. Some in the room may realize during this discussion that they need to be baptized scripturally. Be prepared for that, and treat it as a gift, not a crisis.

Be patient and kind. People who were baptized in a denomination, or as children, were doing what they believed was right. The goal is never to make someone feel foolish about their past. It's to help them walk clearly in the truth now.

Don't rush the personal questions. Part 4 is where the lesson becomes real. Give the group time to consider Question 10 in particular. Some people have been carrying doubts for years and have never said it out loud. This may be the first time.

Have a next step ready. If someone expresses that they need to be baptized, don't leave them with a question mark. Know who they can talk to, and be prepared to connect them with an elder, preacher, or mature Christian before they leave the room. The baptistry is there. This can be resolved.

Emphasize what the sermon emphasized: this lesson isn't designed to shake anyone's faith. It's designed to give people what 1 John 5:13 promises—the ability to know.

5-Day Devotional: Understanding Biblical Baptism

Day 1: The Foundation of Faith
Reading: Mark 16:15-16; Acts 2:37-38

Devotional: Before we can properly understand baptism, we must grasp what precedes it. Faith is not mere intellectual agreement but a wholehearted conviction that changes how we live. The Ethiopian eunuch declared, "I believe with all my heart" before entering the water. This complete faith—not peer pressure, not romantic interests, not family expectations—must drive our obedience. Consider today: What is the foundation of your faith? Is your relationship with Christ built on genuine conviction or external motivations? True discipleship begins when we believe deeply enough to act on that belief. Examine your heart and ensure your faith rests on the solid rock of personal conviction in Jesus Christ.

Day 2: Knowledge That Leads to Life
Reading: Romans 6:3-4; Colossians 2:12

Devotional: Paul describes baptism as a burial with Christ, a vivid image requiring understanding. You cannot be "taught wrong and baptized right." The early Christians knew they were being buried with Christ in baptism to rise to new life. They understood baptism wasn't merely symbolic but transformative, the moment when God washes away sin. Many today are baptized without comprehending its purpose, like someone repeating words in a foreign language for money. The words mean nothing without understanding. Reflect today on what you understood when you obeyed the gospel. Did you know baptism was for remission of sins? Did you understand you were entering Christ's body? If doubts linger, remember: God offers peace, not perpetual uncertainty about your salvation.

Day 3: The Innocence of Children
Reading: Matthew 18:1-5; Ezekiel 18:20

Devotional: Jesus held up children as examples of the humility and purity required for the kingdom. He never suggested they were sinful creatures needing immediate cleansing. The doctrine of original sin—that babies inherit Adam's guilt—contradicts Scripture's clear teaching: "The soul who sins shall die . . . the son shall not bear the iniquity of the father." Babies are not born wicked; they are born innocent. When Jesus said we must "become as little children," He wasn't describing conversion from inherited sin but rather a return to humble trust. Today, thank God that He judges each person according to his own choices, not the failures of ancestors. His justice is perfect, and His mercy extends to all who cannot yet choose.

Day 4: Buried and Raised
Reading: Acts 8:35-39; Romans 6:3-6

Devotional: Philip and the Ethiopian "went down into the water" together. Why did both descend if sprinkling sufficed? Because baptism is immersion—a burial. The Greek word baptizo means to submerge, to plunge beneath. This isn't mere semantics; it's the very picture of death, burial, and resurrection that gives baptism its power. When we go beneath the water, we bury our old self with Christ. When we emerge, we rise to walk in newness of life. Sprinkling or pouring misses this beautiful symbolism entirely. Consider the completeness of Christ's sacrifice and your response. Just as Jesus was fully buried and fully raised, your baptism should fully immerse you in His death and resurrection. Have you experienced this complete burial and rising?

Day 5: Peace in Assurance
Reading: 1 John 5:13; 2 Peter 1:10-11

Devotional: John wrote "that you may know that you have eternal life"—not guess, not hope, but know. Living with constant doubt about your salvation is not God's plan for His children. If questions about your baptism torment you: whether you truly understood, whether peer pressure influenced you, whether your knowledge was sufficient—you cannot have the peace Christ offers. The solution is simple: there is water available near you, and you can settle this matter. Getting baptized again with full understanding and conviction either confirms what was already valid or corrects what was lacking. Either way, you gain peace. Don't live in misery wondering. Make your calling and election sure. God desires you to walk confidently as His child, assured of your salvation through obedient faith.
