The Testimony of Christ and Eternal Life

Devotional

Day 1: Water, Blood, and Spirit: Three Witnesses Agreeing as One

The baptism, crucifixion, and Holy Spirit form an unbreakable chain of testimony confirming Jesus’ divine identity. These historical events witnessed by many are not isolated moments but a unified declaration of Christ’s eternal nature. The Spirit’s role is not passive—He actively reveals truth, anchoring faith in tangible realities rather than abstract ideas. To deny any part of this threefold witness is to reject God’s own testimony. The water and blood prove the Son’s full divinity did not abandon Him at the cross. Eternal life rests on this unshakable foundation. [32:01]

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 doubt Christ’s full divinity during His earthly life? How does the threefold witness strengthen your confidence in Him?

Day 2: The Incarnate Word Dwelt Among Us

God’s eternal Son took on flesh without ceasing to be God—a mystery that crushes human logic but fulfills divine promise. The manger and the cross both declare His full humanity and full deity. Adoptionist heresies crumble before the eyewitness accounts of disciples who touched, heard, and saw the Word-made-flesh. Every meal shared, wound healed, and tear shed by Jesus confirms He was no temporary vessel for divinity. The incarnation remains Christianity’s scandalous cornerstone. [32:48]

And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.
(John 1:14, ESV)

Reflection: How does Jesus’ full humanity deepen your trust in His understanding of your struggles?

Day 3: Eternal Life Only in the Son

Salvation cannot be earned, borrowed, or discovered—it is received through Christ alone. The false teachers’ denial of Jesus’ divinity severed access to eternal life, leaving only human effort. But God’s testimony roars: life flows exclusively from union with the Son. To “have” Him is to possess resurrection power now and forever. This exclusivity offends modern sensibilities but liberates believers from the tyranny of self-salvation. Eternal life begins at faith, not death. [48:41]

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.
(1 John 5:11–12, ESV)

Reflection: What areas of your life still operate as if salvation depends on your performance rather than Christ’s finished work?

Day 4: God’s Testimony Greater Than Man’s

Human opinions shift like sand, but God’s witness stands immovable. The Creator’s testimony about His Son outweighs all earthly philosophies, scientific theories, and personal feelings. To disbelieve God’s word is not intellectual disagreement—it is to call the Almighty a liar. Yet those who receive His testimony find their doubts silenced by the Spirit’s inner confirmation. Faith rests not in eloquence or evidence, but in the character of the God who cannot lie. [40:29]

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.
(1 John 5:9, ESV)

Reflection: When have you prioritized human reasoning over God’s testimony? How can you cultivate greater trust in His truth?

Day 5: Assurance Written for Believers

God etched His promises in ink so His children would never wonder about their salvation. Feelings falter, but the written Word remains. The same Spirit who inspired Scripture testifies through it, crushing the enemy’s accusations. Assurance isn’t presumption—it’s claiming what God has already declared. Those united to Christ need no secondary proofs. The epistle’s purpose pulses clear: know you’re saved because God said so. [53:12]

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 5:13, ESV)

Reflection: What doubts vanish when you anchor your assurance to God’s written promises rather than shifting emotions?

Sermon Summary

John confronts the lie that Jesus was merely a man at the cross, as though the divine Christ came upon Him at His baptism and left before His death. First John 5:6-13 brings the receipts: Jesus came by water and blood. The water points to His baptism, the blood points to His crucifixion, and both testify to the same Jesus Christ, the Son of God. Nothing changed. The divine Christ baptized in the river is the same divine Christ who hung on the cross.

The Holy Spirit gives an impeccable testimony because He is the Spirit of truth. The Spirit identified Jesus as God’s Messiah at His baptism and continues to make Jesus known in human hearts. The Father, the Word, and the Holy Spirit stand in agreement with the historic facts of Christ’s incarnation, baptism, death, resurrection, and saving work. The testimony is not built on religious feeling or somebody’s opinion. God Himself has testified concerning His Son.

John then presses the issue home: if people receive the witness of flawed men, God’s witness is greater. Unbelief does not make Christ less true. Unbelief calls God a liar because God has declared that Jesus is the Christ, God in the flesh, and the only Savior. Belief does not determine whether the testimony is true. Belief determines whether a person receives the life God has given in His Son.

The testimony is also indispensable because eternal life is found nowhere except in Christ. “He who has the Son has life.” That is plain, straightforward, and exclusive. Eternal life is a free gift, but the Son of God is the only means of receiving it. False teachers and the enemy keep trying to stir up doubt, confusion, and defeat, but God’s declaration does not move. Those who have Christ have life, and nothing can separate them from the love of Christ.

John writes to believers so they may know they have eternal life. Assurance rests on God’s Word, not on the ups and downs of feelings, performance, church background, or denominational preference. Faith in the Lord Jesus Christ brings a person from death into life. Good works, obedience, and fellowship matter as byproducts of the relationship, but they do not create the relationship. God’s testimony settles it: Jesus is the Son of God, and there is no life apart from Him.

Key Takeaways

1. Jesus came by water and blood. The baptism and crucifixion cannot be separated without destroying the gospel. Christ did not become divine for a season and then die as an ordinary man. The Son who fulfilled all righteousness in the water is the same Son who shed His blood as the true Passover Lamb. [33:08]
2. God’s witness is greater than man’s. Human testimony has limits, blind spots, and failures, yet people rely on it every day. God’s testimony concerning His Son comes from the Spirit of truth and cannot be improved upon. Faith rests on what God has declared, not on cultural approval or personal uncertainty. [40:14]
3. Unbelief calls God a liar. The rejection of Christ is not merely an intellectual disagreement with religious claims. God has testified that His Son is the Christ, the Savior, and the giver of life. To refuse that testimony is to reject the God who spoke it. [44:52]
4. The Son alone gives eternal life. Eternal life is not found in sincerity, morality, religion, or a church label. The gift comes only in Christ because Christ Himself is the resurrection and the life. Those who have the Son possess what death cannot take away. [49:57]
5. Assurance rests on God’s Word. Feelings rise and fall, and spiritual struggles can cloud the mind. God’s promise remains definite: whoever hears Christ’s Word and believes has passed from death into life. Salvation rests on Christ’s finished work and God’s faithful testimony. [53:50]

Bible Reading

1 John 5:6-13
“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. 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.” [28:01]

John 5:24
“Truly, truly, I say to you, whoever hears my word and believes him who sent me has eternal life. He does not come into judgment, but has passed from death to life.” [54:16]

John 1:12
“But to all who did receive him, who believed in his name, he gave the right to become children of God,” [45:57]

Observation questions

In 1 John 5:6-13, what three witnesses are named, and what do they agree about?
What do “water” and “blood” point to in Jesus’ earthly ministry, and why does John stress both rather than water alone? [33:08]
According to 1 John 5:9-10, how does John compare human testimony with God’s testimony about His Son? [40:14]
What repeated contrast does John make between the person who has the Son and the person who does not have the Son? [49:57]

Interpretation questions

Why does it matter for the gospel that the same Jesus Christ was present as the Son of God at both His baptism and His crucifixion? What would be lost if Jesus were merely a man when He died? [34:05]
John says that refusing God’s testimony about His Son makes God a liar. Why is unbelief more serious than simply having unanswered questions or intellectual uncertainty? [44:52]
How does the Spirit’s witness help believers know Christ personally while still grounding their faith in the historical reality of Jesus’ life, death, and resurrection? [38:44]
John writes so believers may know they have eternal life. How does this purpose shape the way Christians should understand assurance when feelings or spiritual performance are weak? [53:14]

Application questions

Where are you most tempted to base your assurance—your feelings, your recent obedience, your church background, or God’s promise in Christ? What would it look like to return to God’s testimony this week? [53:48]
When doubts arise about whether you belong to God, what specific truths from 1 John 5:6-13 and John 5:24 can you speak back to those doubts? [54:16]
Jesus alone gives eternal life. Are there places where you are tempted to look for life, acceptance, or security apart from Christ—such as success, morality, relationships, or religious activity? [49:33]
Believing in Jesus means receiving God’s testimony that Jesus is the Christ, the Son of God. How clearly would your daily choices, conversations, and priorities show that you trust Him as Lord? [47:15]
Good works, obedience, and fellowship are important fruits of knowing Christ, but they do not earn a relationship with Him. How can this truth bring both humility when you are doing well and hope when you have failed? [55:23]
Is there someone in your life who is confused about who Jesus is or thinks that eternal life can be found through another path? What is one gracious and clear way you could point them to the testimony God has given about His Son? [59:02]

#FaithInJesus

“All that matters is that you have believed on the name of the son of God. He takes care of the rest. Have you believed on Jesus Christ? And if so, then continue to believe God's word and his testimony because it is true. There is no other way to the father. There is no other sincere religion. There is no particular denomination. There is only the son of God. Life only is found in him. That is the testimony of the father.”

#WashedByTheBlood

“That God became flesh and blood, became like us, but lived perfectly according to your law where we fail repeatedly so that he was perfectly suited to be the sacrifice, the true Passover lamb to take away the sins of the world when he hung on that cross and shed his precious blood. And by that blood, all of your children have been washed clean. But by that same blood, anyone separated from you right now can be washed clean. And they can become your child by believing on Jesus Christ.”

#EternalLife

“He makes very clear that belief in the reality of who Jesus is, belief in the name of Jesus, belief in the testimony of God about Jesus is a requirement for eternal life in Christ. So once the gospel message has been heard and understood, only one thing remains. Do you believe it to be true or not? And your belief does not determine whether it's true or not. Your belief determines or lack thereof determines where you will spend eternity. Whether you will be with Jesus Christ, the son of God, or separated from God for all eternity.”
