John 16:9's role in evangelism today?
How can John 16:9 guide us in evangelism efforts today?

The Verse

“ …and when He comes, He will convict the world regarding sin and righteousness and judgment: regarding sin, because they do not believe in Me.” (John 16:8-9)


Key Truths in John 16:9

• The Holy Spirit’s first work in evangelism is conviction.

• The fundamental sin He pinpoints is unbelief in Jesus.

• Evangelism that ignores unbelief as the root issue misses Christ’s own focus.


Why Unbelief Is the Central Issue

• Sin is broader than outward acts; its core is rejecting the Son (John 3:18).

• All other sins flow from a heart that refuses Christ’s authority (Romans 1:21-25).

• Faith in Jesus reverses that posture and restores fellowship with God (John 20:31).


Practical Guidance for Evangelism Today

1. Keep Christ at the Center

– Present who Jesus is, what He did, and why He alone saves (Acts 4:12).

– Avoid drifting into mere moralism; people need a Person, not a program.

2. Partner With the Spirit’s Convicting Work

– Pray before, during, and after conversations (1 Timothy 2:1-4).

– Trust that conviction is His role, not ours; we witness, He convinces (1 Corinthians 2:4-5).

3. Address Unbelief Directly but Graciously

– Ask questions that surface what a person believes about Jesus (Matthew 16:15).

– Share Scripture that exposes unbelief as sin:

• “Whoever does not believe has already been condemned.” (John 3:18)

• “The god of this age has blinded the minds of the unbelieving.” (2 Corinthians 4:4)

4. Present the Gospel’s Remedy

– Show how the cross answers both guilt and unbelief (1 Peter 3:18).

– Highlight resurrection proof (Acts 17:31).

– Invite repentance and faith (Acts 2:38).

5. Use Scripture Confidently

– Faith comes by hearing the Word (Romans 10:17).

– God’s Word will not return void (Isaiah 55:11).

6. Cultivate Humble Boldness

– We speak with gentle respect (1 Peter 3:15) yet refuse to soften the call to believe.

– Remember our own rescue from unbelief (Ephesians 2:8-9).


Encouragement for the Evangelist

• The Spirit is already at work in people’s hearts; we join His mission.

• Success is measured by faithfulness to proclaim, not by visible results (1 Corinthians 3:6-7).

• Every conversation that lifts up Jesus confronts unbelief and opens the door to saving faith.
