Small Group Discussion Guide
"The Testimony That Changes Everything"
Based on 1 John 5:6-12
A Note to Facilitators: This guide is designed for a 60–90 minute group meeting. You know your group best — feel free to skip questions, linger where conversation is rich, or swap in the Optional Deep Dive questions if your group is ready to go further. You don't need to be a theological expert to lead this discussion. Your job is to create a safe space for honest conversation and to keep things moving. The Holy Spirit will do the rest.
OVERVIEW
In this message, Pastor Carl walked us through one of the more unusual passages in 1 John, showing us that understanding who wrote the Bible and why they wrote it completely changes how we read it. Using John 5:6-12 as his text, he revealed that the Apostle John — Jesus' first cousin, closest disciple, and the man entrusted with caring for Jesus' own mother — was writing to second-generation Christians who were being influenced by Greek philosophical ideas (particularly Gnosticism) that distorted who Jesus really was. The central message: Jesus was not a human being who became God at his baptism. Jesus is the pre-existing, all-creating God who came in the flesh — and that truth is the very foundation of the gospel and of our eternal life.
SECTION 1: ICEBREAKER
(5–10 minutes)
Opening Question — Choose one based on your group's personality:
Option A (lighter, fun):
"Think of someone in your life whose advice or opinion you trust above almost anyone else's — maybe a grandparent, a mentor, an old friend. What makes you trust them so much? What is it about them that makes their words carry weight?"
Option B (more reflective):
"Has there ever been a time when learning who said something completely changed how you felt about what was said? Tell us about it."
[Leader Tip]: This icebreaker is designed to naturally lead into the sermon's theme — that John's unique relationship with Jesus gives his words extraordinary authority. Don't rush to make that connection yet; let people enjoy the sharing first. You can bridge to it when you move into the Scripture section.
SECTION 2: SCRIPTURE READING
(5 minutes)
Ask a volunteer to read the following passage aloud. Encourage everyone else to follow along and underline or circle any words or phrases that stand out to them.
Primary Text: 1 John 5:6-12 (NIV)
"This is the one who came by water and blood — Jesus Christ. He did not come by water only, but by water and blood. And it is the Spirit who testifies, because the Spirit is truth. For there are three that testify: the Spirit, the water and the blood; and the three are in agreement. We accept human testimony, but God's testimony is greater because it is the testimony of God, which he has given about his Son. Whoever believes in the Son of God accepts this testimony. Whoever does not believe God has made him out to be a liar, because they have not believed the testimony God has given about his Son. And this is the testimony: God has given us eternal life, and this life is in his Son. Whoever has the Son has life; whoever does not have the Son of God does not have life."
Supporting Text: John 1:1-3 (NIV)
(Referenced in the sermon to show John's own declaration about who Jesus is)
"In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made."
Supporting Text: John 19:25-27 (NIV)
(The moment Jesus entrusted his mother to John's care)
"Near the cross of Jesus stood his mother, his mother's sister, Mary the wife of Clopas, and Mary Magdalene. When Jesus saw his mother there, and the disciple whom he loved standing nearby, he said to her, 'Woman, here is your son,' and to the disciple, 'Here is your mother.' From that time on, this disciple took her into his own home."
Brief Transition for the Leader:
"Before we jump into our questions, let's take just a moment to remember who wrote these words. Pastor Carl spent a good portion of the sermon helping us understand that the Apostle John was Jesus' first cousin, one of his inner three disciples, the only one who didn't abandon him at the cross, and the man Jesus personally asked to care for his mother. With that in mind, let's dig in."
SECTION 3: DISCUSSION QUESTIONS
(30–45 minutes)
Work through as many of these questions as time allows. Questions are organized from lighter and observational to deeper and more personal. Feel free to skip around based on where your group's energy is.
THEME A: Knowing Who Wrote the Bible
(Helps the group appreciate the human stories behind Scripture)
Question 1 (Observational — good starter):
"Pastor Carl spent a lot of time this week helping us understand who John was before he explained what John wrote. Why do you think knowing the author's background matters so much when we read a passage of Scripture? Did learning about John change how you heard his words?"
[Leader Tip]: There are no wrong answers here. Some people may say context doesn't change anything for them — that's okay. Others may find it deeply meaningful. Let both responses breathe. The goal is to get people thinking about Scripture as a living library with real human authors, not just a rulebook dropped from heaven.
Question 2 (Interpretive):
"Pastor Carl described John as the person who 'knew Jesus best' — as a childhood cousin, as one of the inner three disciples, as the man present at the cross, and as the caretaker of Jesus' mother for the rest of her life. If you had to describe the kind of authority that kind of relationship gives someone, how would you put it into your own words?"
THEME B: Understanding the Historical Context
(Helps the group grasp why John wrote what he wrote)
Question 3 (Interpretive — slightly deeper):
"The sermon explained that second-generation Christians were being influenced by a Greek philosophy called Gnosticism, which taught that the spirit world is good and the physical world is bad or evil. Because of this, some people were teaching that Jesus couldn't have actually come 'in the flesh' as God — he must have just been a regular human who became divine at his baptism. Why would that idea be so dangerous to the Christian faith? What falls apart if Jesus wasn't God from the very beginning?"
[Leader Tip]: If your group isn't sure where to start, you can prompt them with: "Think about what the gospel is — God coming to rescue us from sin and death. Does that rescue mission work if Jesus is just a very wise human being?" This question is important but can feel abstract. Keep bringing it back to the practical: "What does this mean for us?"
Question 4 (Connecting past to present):
"Pastor Carl pointed out that the arguments haven't really changed — they've just gotten new language. Today, people might say things like, 'Jesus was a great moral teacher,' or 'We all have the spark of the divine within us,' or 'There are many paths to God.' Have you heard ideas like these? How do you usually respond when you do?"
[Leader Tip]: This question can surface some real-life experiences and may generate good discussion. Be careful not to let it become a session of "bashing" people who hold these views — keep the tone curious and gracious. The goal is to help people articulate what they believe and understand why it matters, not to create an us-vs-them mentality.
THEME C: The Core Claim — Who Is Jesus?
(The heart of the message)
Question 5 (Interpretive — central question):
"Pastor Carl quoted C.S. Lewis from Mere Christianity, who argued that Jesus left us only three real options: he was a liar, a lunatic, or he truly is Lord. Lewis said we cannot simply call him a 'great moral teacher' and leave it at that. Do you find that argument compelling? Why or why not? Is there anything about it that challenges you or raises questions for you?"
Question 6 (Personal — invites honest sharing):
"Has there ever been a season in your own life when you were tempted to reduce Jesus to something less than who he truly is — maybe a good example to follow, a source of comfort, or a helpful philosophy — rather than the living God? What brought you back, or what is bringing you back now?"
[Leader Tip]: This is a vulnerable question. Model openness yourself if you're the facilitator. If the group goes quiet, you might share briefly from your own experience first, then invite others. Remind the group that honest wrestling is healthy — this is a safe space.
THEME D: The Testimony and What It Means for Us
(Connecting the passage to eternal life and personal faith)
Question 7 (Interpretive):
"In verses 11-12, John makes a very direct statement: 'God has given us eternal life, and this life is in his Son. Whoever has the Son has life; whoever does not have the Son does not have life.' That's a bold claim with no middle ground. What does it stir up in you when you read those words? Does it feel like good news, or does it feel uncomfortable — or both?"
Question 8 (Community-building):
"Pastor Carl described the gospel as a story — not just a good idea or a philosophy, but the retelling of real events: God made us, we broke the relationship through sin, God himself came in Jesus to restore what was broken, he died and rose again, and he's coming back. In your own words, how would you tell that story to someone who had never heard it before? Take a shot at it — it doesn't have to be perfect."
[Leader Tip]: This question is great for mixed-maturity groups. Newer believers often articulate the gospel beautifully in simple terms, while longer-tenured Christians sometimes over-complicate it. Affirm every attempt. You might even make it fun: "Imagine you have 60 seconds on an elevator with someone — go!"
SECTION 4: PERSONAL APPLICATION
(10–15 minutes)
Transition the group from discussion to personal reflection. You may want to give people 2-3 minutes of quiet to think before sharing.
Reflective Questions — Choose 2-3 based on time:
1. When you think about the Jesus you actually live for day-to-day — the Jesus you pray to, make decisions with, and introduce to others — is that Jesus the pre-existing, all-creating God of the universe? Or has he quietly shrunk a little in your imagination? What might it look like to recapture the full, enormous truth of who he is?
2. Pastor Carl said the gospel is not a good idea or a philosophy — it's news, the retelling of something that actually happened. How does thinking of the gospel as news rather than advice change the way you might share your faith with someone?
3. John was the only disciple who stayed at the cross. He didn't have all the answers, but he stayed close to Jesus even when it was costly. Is there an area of your life right now where staying close to Jesus feels costly or difficult? What would it look like to stay anyway?
4. The sermon reminded us that John took Jesus' mother into his own home and cared for her — a practical, costly act of love that grew directly out of his relationship with Jesus. Is there someone in your life God might be calling you to care for in a practical, concrete way this week?
"This Week" Challenge
Offer these as options — invite people to choose one that resonates with them:
📖 Read the Gospel of John chapters 1-3 this week with fresh eyes, remembering that it was written by someone who played with Jesus as a child and stood at the foot of his cross.
🗣️ Practice telling the gospel story in your own words — out loud, to yourself in the car, or to a trusted friend. Time yourself. Can you do it in two minutes? In 30 seconds?
🤔 Reflect on a question someone in your life has raised about Jesus. Write it down. Bring it back to the group, or bring it to your pastor or a trusted mentor.
🙏 Pray this week specifically about who Jesus really is — not just what he does for you, but who he is. Ask him to make his full identity more real to you.
SECTION 5: PRAYER FOCUS
(5–10 minutes)
Close your time together in prayer. You can pray as a group, invite people to pray aloud, or have the facilitator pray over the themes below.
Suggested Prayer Topics:
Gratitude — Thank God for the extraordinary gift of Scripture, written by real people with real relationships, preserved for us across centuries.
Clarity — Ask the Holy Spirit to make the truth of who Jesus is more vivid and real in each person's daily life.
Courage — Pray for boldness to hold onto and share the full truth of the gospel, especially when cultural voices offer a watered-down version of Jesus.
Openness — Ask God to reveal any areas where we've quietly reduced Jesus to something smaller than he is, and invite him to expand our view of him.
Those who don't yet know — Pray for specific people in your lives who have not yet encountered the real Jesus — by name, if the group is willing.
If your group is comfortable, close by reading 1 John 5:11-12 together as a declaration of faith:
"And this is the testimony: God has given us eternal life, and this life is in his Son. Whoever has the Son has life; whoever does not have the Son of God does not have life."
SECTION 6: OPTIONAL DEEP DIVE
(For groups wanting to go further — use these as bonus questions or for a second week)
Deep Dive Question 1:
"The sermon explained that the New Testament was written over about 50 years (roughly 50–100 AD) and that different books address different questions depending on when they were written and who their audience was. How does understanding the Bible as a library — with different authors, audiences, and purposes — change the way you approach reading it? Does it make Scripture feel more trustworthy or less? Why?"
Deep Dive Question 2:
"Gnosticism taught that the physical world is corrupt or evil and that only the spiritual realm is truly good. While most of us wouldn't call ourselves Gnostics, are there ways that idea still sneaks into Christian thinking today — for example, the idea that 'spiritual' activities (prayer, church, Bible study) are more important than 'physical' ones (work, relationships, caring for our bodies)? How does the Incarnation — God coming in the flesh — challenge that kind of thinking?"
Deep Dive Question 3:
"John 19:26-27 records the moment Jesus, in the middle of his suffering on the cross, looked down and made sure his mother would be cared for — entrusting her to John. What does that moment tell you about the character of Jesus? What does it tell you about the kind of community and family he calls us to be for one another?"
