Can I Trust What I Believe About Jesus?

Scripture Covered

1 John 5:6–12

We live in a world filled with opinions about Jesus.

Some see Him as a wise teacher. Others see Him as a moral example, a political figure, a therapist, or simply one religious option among many. But if eternity hangs in the balance, opinions aren't enough.

In 1 John 5:6–12, the Apostle John answers one of the biggest questions people still ask today:

Can I trust what I believe about Jesus?

John's answer is clear: our confidence in Jesus is not grounded in blind faith, but in truth, testimony, and historical reality.

1. Christianity Is Rooted in Real History

John begins by reminding us that Jesus "came by water and blood."

These references point to Jesus' baptism and His crucifixion—the historical bookends of His earthly ministry. John emphasizes that Jesus wasn't merely a man who temporarily carried divine power. He was God in the flesh from beginning to end.

Why does that matter?

Because if Jesus is just a man, then His death is just a tragedy. But if Jesus is God in the flesh, then the cross becomes the place where God Himself bears our sin and reconciles us to Himself.

John's defense of Jesus isn't theological trivia. It's the foundation of our salvation.

2. God Has Given Testimony About His Son

John then points to the witness of the Holy Spirit.

Just as Jesus promised, the Spirit testifies about who He is. The Spirit, the baptism of Jesus, and the cross all point to the same conclusion:

Jesus is exactly who He claimed to be: the Son of God.

John uses courtroom language throughout this passage. Like a skilled attorney, he presents evidence and calls witnesses.

His message is simple:

Faith isn't based on positive vibes, wishful thinking, or blind hope. It's grounded in God's testimony and the historical reality of Jesus Christ.

3. The Verdict Is Personal

After presenting the evidence, John shifts the focus from Jesus to us.

The question is no longer:

"Who is Jesus?"

The question becomes:

"What will I do with Him?"

A helpful picture is that of a drowning person being thrown a lifeline.

The issue isn't whether the rope exists.

The issue is whether you trust the person offering the rescue.

God has thrown humanity a lifeline through Jesus Christ. But a lifeline only saves the person who grabs hold of it.

4. Eternal Life Is Available Right Now

John then arrives at the heart of the passage: "The one who has the Son has life."

Notice what he doesn't say.

He doesn't say we might have life someday.

He doesn't say we can hope to have life eventually.

He says we have life.

Eternal life isn't merely a future destination. It begins the moment we trust Jesus. The life of God's kingdom breaks into our present reality today.

Eternal life is not just a future promise to be received; it is a present possession to be enjoyed because Jesus is already ours.

5. A Hard Truth We Cannot Ignore

John ends with a sobering reality: "The one who does not have the Son of God does not have life."

Jesus Himself said: "I am the way, the truth, and the life. No one comes to the Father except through me." (John 14:6)

In a culture that prefers many paths and many truths, John's words can feel uncomfortable.

But truth is not determined by what is popular or culturally acceptable.

Eternal life is available to everyone, but not everyone will accept it.

To reject Jesus is to reject the very life God offers.

Big Takeaway

Christianity isn't about following a philosophy; it's about following a real, risen Savior who offers eternal life now.

Our faith is grounded in publicly testable historical events, not merely private spiritual experiences. The baptism of Jesus, the cross of Jesus, the resurrection of Jesus, and the testimony of the Holy Spirit all point to the same conclusion:

Jesus is the Son of God, and life is found in Him alone.

This Week's Challenge

Take some time this week to honestly answer this question:

What am I doing with the evidence God has given about Jesus?

If you're a believer, consider how the reality of eternal life is shaping your everyday life.

If you're not yet following Jesus, ask yourself whether you've truly responded to the lifeline God has offered through His Son.

Reflective Question

In a world full of opinions about Jesus, am I trusting popular opinion, or God's testimony?
