The Son, the Blood, and Eternal Life

Sep 23, 2026

Devotional

Day 1: Water and Blood: The Twin Witnesses of Christ’s Mission

John confronts a dangerous half-truth: a “water only” gospel that celebrates Jesus’ teachings but rejects his crucifixion. Eternal life hinges on both Christ’s baptismal identification with sinners and his bloody atonement for them. The Spirit testifies to this dual reality, vibrating in believers’ hearts like a tuning fork resonating with truth. To deny either water or blood is to reject God’s full testimony. [25:28]

This is he who came by water and blood—Jesus Christ; not by the water only but by the water and the blood. And the Spirit is the one who testifies, because the Spirit is the truth. For there are three that testify: the Spirit and the water and the blood; and these three agree. (1 John 5:6-8, ESV)

Reflection: Where have you been tempted to downplay the “blood” of Christ’s sacrifice while emphasizing the “water” of his teachings? How does the Spirit’s witness in your heart confirm both as essential?

Day 2: The Trinity’s Symphony of Salvation

Salvation is a triune collaboration: the Father sends, the Son obeys, the Spirit testifies. The Father’s love isn’t bought by the Son’s blood but flows freely through it. Jesus turns his face toward sinners so the Father’s face might never turn away from us. The Spirit hums this truth in believers, making Christ’s finished work personal. [34:15]

In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him. In this is love, not that we have loved God but that he loved us and sent his Son to be the propitiation for our sins. (1 John 4:9-10, ESV)

Reflection: When have you struggled to see the Father’s love as the source—not the result—of Christ’s sacrifice? How does the Spirit’s presence reassure you of this love today?

Day 3: Believing Into: When Truth Becomes Embrace

Belief isn’t mere agreement with facts but entrusting your full weight to Christ. Like a child recognizing a parent’s voice in a crowded nursery, the Spirit makes Christ’s claim—“She’s mine”—echo in the soul. Eternal life isn’t a theological concept but a relational reality: having the Son means his life pulses through yours. [45:20]

Whoever has the Son has life; whoever does not have the Son of God does not have life. I write these things to you who believe in the name of the Son of God, that you may know that you have eternal life. (1 John 5:12-13, ESV)

Reflection: When has “knowing about Jesus” shifted to “knowing you have Jesus”? How does the Spirit’s resonance differ from mere emotional certainty?

Day 4: Stewarding the Testimony: Welcome, Not Weapon

God’s exclusive truth about Christ demands inclusive love for others. Like studying a friend’s beliefs before sharing the gospel, humility listens before speaking. The “no other stream” of Christ’s salvation is both a boundary and an invitation—a rescue to offer, not a club to wield. [56:57]

For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him. (John 3:16-17, ESV)

Reflection: Who in your life could articulate what you believe about Jesus? How might listening to their story deepen your ability to share yours?

Day 5: The Tuning Fork of Eternal Assurance

The Spirit’s witness isn’t mystical whispers but a sustained vibration aligning believers with Christ’s finished work. Just as a tuning fork quivers when its note is played, the heart resonates when gospel truth is proclaimed. This assurance isn’t self-generated—it’s the Spirit’s gift, confirming we belong to the Son. [50:20]

The Spirit himself bears witness with our spirit that we are children of God, and if children, then heirs—heirs of God and fellow heirs with Christ. (Romans 8:16-17, ESV)

Reflection: When has external doubt or internal struggle caused you to “check the tuning” of your heart? How does the Spirit’s steady witness redirect you to Christ’s “It is finished”?

Sermon Summary

John writes as a pastor who wants believers to know that they belong to the real Jesus and have eternal life in him. His letter keeps circling through truth, obedience, and love, not as traps meant to make people fail, but as tests that give assurance. John first presses the truth of Jesus’ person: Jesus is the Christ, the Son of God, fully God and fully man. He then presses the truth of Jesus’ work: Jesus came not by water only, but by water and blood.

The water points to Jesus’ baptism, where the Father identifies him as the royal Son and the suffering Servant. Jesus does not become God’s Son at his baptism. The Father announces who he already is and what he came to do. Jesus identifies with sinful people, yet the heavens open to declare that this beloved Son will accomplish his kingly mission through suffering.

The blood points to the cross. A water only gospel can admire Jesus as teacher, miracle worker, blessing, and example, but it cannot give eternal life. The blood means atonement, forgiveness, redemption, justification, peace, and reconciliation. Jesus took human nature in his birth, and he took human sin in his death. The incarnation matters because Jesus had to take flesh in order to take the sinner’s place, but the incarnation without substitution would not save anyone. The heart of the gospel is not merely discipleship. The heart of the gospel is substitution.

The Spirit testifies with the water and the blood because the Spirit is the truth. The Father sends in love, the Son comes in obedient love, and the Spirit brings Christ’s finished work home to human hearts. The Father’s love does not need to be purchased from a reluctant God. Salvation is God’s love at God’s expense, accomplished by the Son and given through the Spirit.

John therefore turns from the three witnesses to the human response. Belief means more than agreeing that certain facts are true. Belief is believing God, submitting to his testimony, and believing into the Son. It means placing all the weight of life inside of Christ and letting him have the sinner. Whoever has the Son has life because everything Christ is and does becomes for that person a gift.

The Spirit gives inward testimony like a tuning fork vibrating when its true note is played. The love and work of Jesus resonate in the heart because the Spirit joins believers to Christ. This assurance also creates a calling: God’s testimony must be stewarded in humility, listening, honesty, and love. The exclusive truth that there is no other stream makes the invitation gloriously wide: whoever comes to Christ may come and drink.

Key Takeaways

1. Reject the water only gospel [25:28] A water only gospel can admire Jesus while refusing the cross. Jesus’ example, miracles, and teaching are beautiful, but they cannot atone for guilt before a holy God. The blood keeps the center where John keeps it: sinners need a Savior and sacrifice, not merely an instructor. [25:28]
2. Jesus took flesh and took the place [29:44] The incarnation and atonement belong together. Jesus took human nature so that he could stand where guilty people deserved to stand. His death means that the Father turned away from the Son on the cross so that those united to Christ will never be finally forsaken. [29:44]
3. Believe God, not merely in God [43:18] Belief receives God’s testimony about his Son rather than editing it according to personal preference. Intellectual agreement can remain distant and unchanged. Believing into Christ means giving over control, placing life’s full weight on him, and discovering that submission to this love is freedom rather than oppression. [43:18]
4. Having the Son means having life [48:31] Christ does his thing for those who have him. His righteousness, death, resurrection life, advocacy, love, and promise of home are not abstract truths but gifts for his people. Death strips away every lesser possession until the only decisive question remains: does this person have the Son? [48:31]
5. Offer a welcome, not a weapon [01:04:35] God’s testimony must be spoken with both honesty and humility. Love listens long enough to understand what another person actually believes, and love speaks clearly enough that they can know what Christ offers. The exclusive claim of Christ does not narrow the invitation, because whoever comes to him will never be driven away.

Bible Reading

1 John 5:6-12
“This is he who came by water and blood—Jesus Christ; not by the water only but by the water and the blood. And the Spirit is the one who testifies, because the Spirit is the truth. For there are three that testify: the Spirit and the water and the blood; and these three agree. If we receive the testimony of men, the testimony of God is greater, for this is the testimony of God that he has borne concerning his Son. Whoever believes in the Son of God has the testimony in himself. Whoever does not believe God has made him a liar, because he has not believed in the testimony that God has borne concerning his Son. And this is the testimony, that God gave 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.” [15:10]

John 3:16
“For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.” [18:10]

John 6:37
“All that the Father gives me will come to me, and whoever comes to me I will never cast out.” [01:06:10]

Observation questions

In 1 John 5:6–12, what three witnesses does John name, and what does he say they agree about? [15:24]
What does the passage say God has given, where is that life found, and what is the difference between having the Son and not having the Son? [16:13]
What does the water point to in Jesus’ life, and what does his baptism reveal about both his identity and his mission? [20:43]
What good things can a “water only” view of Jesus acknowledge, and what essential part of Jesus’ work does it leave out? [25:28]

Interpretation questions

Why does John stress that Jesus came not by water only, but by water and blood? What would be lost if Jesus were seen only as a teacher, example, and miracle worker rather than as the Savior who died for sinners? [27:48]
How does Jesus’ baptism connect his royal identity as God’s Son with his mission of suffering? Why does it matter that Jesus did not become God’s Son at his baptism? [22:43]
John says that refusing God’s testimony about his Son is more serious than merely having unanswered questions. What is the difference between honest doubt and reshaping Jesus according to personal preference? [43:18]
What does it mean that the Spirit gives testimony “in” believers? How does the Spirit’s inward witness give assurance while still pointing believers back to the real, historical work of Jesus? [49:41]

Application questions

Is there any way that Jesus has become mainly an example, helper, teacher, or source of encouragement in your thinking, while his substitutionary death has moved to the background? What would it look like to bring the cross back to the center? [29:44]
When guilt, failure, or shame rises up, where do you usually look for relief: your own efforts, self-improvement, distraction, or Christ’s finished work? How does Jesus taking your place change the way you face guilt? [31:07]
Believing God means more than believing that God exists; it means receiving his testimony about his Son. Is there an area where you are tempted to edit, resist, or keep control over what God says? What might trusting him in that area look like? [43:18]
To believe into Christ is to place the full weight of life on him and let him have you. What makes that kind of surrender feel difficult or risky? Where have you found that submission to Christ brings freedom rather than oppression? [45:09]
“Whoever has the Son has life.” When lesser possessions, accomplishments, relationships, or security feel especially important, how can this promise reset what matters most? [54:17]
Think of someone you love who does not appear to know Christ. Can you clearly and respectfully describe what that person believes about life, God, meaning, or eternity? What is one way you could listen more carefully before looking for an opportunity to speak honestly about Jesus? [58:32]
Jesus’ invitation is open to whoever comes to him, and he will never drive that person away. Are you more likely to avoid speaking because you fear offending, or to speak without first listening well? What would it look like this week to offer Christ as a welcome rather than use truth as a weapon? [01:04:44]

#GospelSubstitution

“Y'all, it would do me no eternal good if the Lord had taken my flesh, and he had not taken my place. That's the heart of the I mean, and so, as important as it was everything that we said last week, that the Son of God truly came in the flesh because he could not take my place unless he took my flesh. But it would not be enough, the incarnation would not be enough without the atonement. Okay? It would not do any good to take our flesh, if he does not also take our place, that the heart of the gospel is substitution.”

34s

#JesusTheSavior

“The heart of the gospel is not discipleship. Okay? It is substitution. It is the atonement. The false teaching is that we need an instructor. The false teaching is that we need an inspiration, but that we do not need a savior. The false teaching is a water only gospel. And John says no. Jesus came to us and for us through the water and the blood.”

#ReconciledByChrist

“And then he willingly takes that face and goes where only my face deserves to be. And when he is on that cross, where my face deserves to be, why can I be reconciled to the father? Because what happened to the father's face in that moment? The father's face turned away. His face where my face belonged. And the father who loved him from all eternity turned his face away from his own son that he might forever, forever turn his face towards me. He will never turn his face away from me because he did turn it away from Jesus. That is the testimony of the blood. That is the testimony there of the atonement. Because of his death, we have life.”

#PowerOfTheBlood

“K? What is that saying? It's saying the blood is the linchpin because according to those passages without the blood, we don't have forgiveness, we don't have redemption, we don't have justification, we don't have peace, we don't have reconciliation. Those things are found in the blood. Okay? And the blood just means the crucifixion here or the atonement. Y'all, the atonement just makes no sense. In a therapeutic worldview that thinks that the mission of God is your personal well-being. That's why it sounds so weird to us. It only makes sense in that whole worldview of the scripture that our ultimate problem is not that we're sad or unfulfilled or insecure. That our ultimate problem is that we are sinners before a holy God.”

53s

#JesusIsTheChrist

“Don't be so busy with the fact that we're being told that we have to believe, that we are missing out on what we are being told to believe. Don't just ipso facto resist. Okay? Just by the very fact of it, if we do not that there are exclusive claims. If we do not consider the content of the exclusive claim, what is the exclusive claim? What is the content of that which we are being told to submit to? That Jesus is the Christ, the son of God, who has come in the flesh through the water and the blood to live for me and to die for me and to bring me to God and to give me full fellowship with him and eternal life with him that I might enjoy forever”

#SurrenderToJesus

“That he has done everything, and I bring nothing to the table but the mess, but the junk, but the debt. I mean, look at what we're look at what is being offered to us. Look at what we are being told to believe. To believe into him is to let him have me. That's what this is calling us for. To believe into the son of God is to let him have me so that what? Verse 12. What happens if I let him have me? What? I have him. I have him.”

#JesusIsLife

“We will all get to a place whether you're beautiful, whether you're wealthy, whether you're educated, whether you're successful, whether you've got titles and lands and jewels and properties and family and everything else, we will all get to the place that the only thing that will matter about us is if we have Jesus. And why will that be enough? Because if we have the son, what does verse 12 say? We have life. If we have the son, we have life.”

41s

#TheCrossAtTheCenter

“teaching that eliminates the cross, but he is also opposing any teaching that even diminishes or demotes the cross. He is keeping it central. He is keeping it central here through the language of the blood. And why is he keeping it central? Because for Jesus, it was central. It is the point of his coming. What does he say? For this reason I came. When he is facing the cross, he's like, shall I say, father, save me from this for this reason I came. Why? So that we might be atoned for and that we might be reconciled to God.”
