John 9:25: Power of testimony?
How does John 9:25 demonstrate the power of personal testimony in evangelism?

Setting the Scene

In John 9, Jesus heals a man born blind. The religious leaders interrogate the man, hoping to discredit Jesus. Pressed to label Jesus a sinner, the healed man answers with the unshakable fact of his own experience.


Key Verse: John 9:25

“He answered, ‘Whether He is a sinner I do not know. There is one thing I do know: I was blind, but now I see!’”


Why Personal Testimony Matters

• It is irrefutable: people may debate doctrine, but they cannot deny a changed life.

• It glorifies God by displaying His work in real time.

• It directs attention from the messenger to the Savior.

• It invites listeners to consider what Christ could do for them.


Elements of an Effective Testimony Evident in John 9:25

1. Clarity

– The man states a single, concrete before-and-after: “blind… now I see.”

2. Honesty

– He admits what he does not know: “Whether He is a sinner I do not know.”

3. Christ-centered Focus

– Though unnamed, Jesus is the obvious agent of change.

4. Simplicity

– No complex theology, just a straightforward account of God’s work.

5. Boldness under Pressure

– He speaks despite opposition, modeling courage in witness.


Lessons for Our Evangelism Today

• Share what Christ has done for you in plain language.

• Keep Christ, not self, at the center of the story.

• Do not fear gaps in theological knowledge; testify to what you do know.

• Expect resistance, but trust God to use your story for His glory.

• Let your transformed life be continuous evidence of the gospel’s power.


Supporting Scriptures

Acts 4:20 – “For we cannot stop speaking about what we have seen and heard.”

Revelation 12:11 – “They conquered him by the blood of the Lamb and by the word of their testimony.”

Mark 5:19 – “Go home to your own people and tell them how much the Lord has done for you, and how He has had mercy on you.”


Putting It Into Practice

• Identify a clear “before and after” that highlights Christ’s work in your life.

• Write your story in a few sentences, focusing on God’s action.

• Look for natural moments to share—conversations, social media, small groups.

• Rely on the Holy Spirit to use your words; the results belong to Him.
