Holy Spirit's role in Peter's Acts 4:8 reply?
What role does the Holy Spirit play in Peter's response in Acts 4:8?

Setting the Scene

• Peter and John have just healed the lame man (Acts 3) and preached Christ in the temple.

• The Sanhedrin arrests them, demanding an explanation “by what power or what name” they acted (Acts 4:7).

Acts 4:8 reports: “Then Peter, filled with the Holy Spirit, said to them, ‘Rulers and elders of the people…’ ”.


Filled with the Spirit: Verse Focus

The text explicitly notes that Peter is “filled with the Holy Spirit” before he speaks. This is not a general description of Peter’s character; it highlights a fresh, empowering work of the Spirit at that very moment.


What the Spirit Does in Peter’s Response

• Boldness in the face of intimidation

Luke 12:11-12: “When they bring you before synagogues, rulers, and authorities, do not worry … for the Holy Spirit will teach you at that time what you should say.”

Acts 4:13 shows the rulers are amazed at Peter’s courage.

• Clarity and authority of proclamation

Acts 4:10: “Let it be known to all of you … that by the name of Jesus Christ of Nazareth, whom you crucified … this man stands before you healed.”

1 Corinthians 2:4: “My message and my preaching were not with persuasive words of wisdom, but with a demonstration of the Spirit’s power.”

• Christ-centered focus

– Peter moves immediately from defending the miracle to exalting Jesus (Acts 4:11-12).

John 15:26: “When the Advocate comes … He will testify about Me.”

• Fulfillment of Jesus’ promise of power

Acts 1:8: “You will receive power when the Holy Spirit comes upon you; and you will be My witnesses …”

– Peter’s Spirit-filled words fulfill that promise before the highest Jewish court.

• Wisdom surpassing human learning

– The council notes Peter and John are “unschooled, ordinary men” (Acts 4:13), yet their reasoning is irrefutable.

Isaiah 11:2 speaks of the Spirit of wisdom resting on God’s servant; that same Spirit equips Peter.


Patterns Echoed Throughout Acts

Acts 2:4—Spirit-filled preaching at Pentecost.

Acts 4:31—Believers filled again; they speak God’s word boldly.

Acts 6:10—Opponents “could not stand up to the wisdom the Spirit gave Stephen.”

The Holy Spirit consistently empowers ordinary believers to speak extraordinary truth.


Implications for Believers Today

• The same Spirit indwells every follower of Christ (Romans 8:11).

• Fresh fillings are available whenever witness or courage is needed (Ephesians 5:18).

• Dependence on the Spirit—not human eloquence—remains the key to effective testimony (2 Timothy 1:7).

Acts 4:8 shows that Peter’s bold, Christ-exalting defense is entirely a work of the Holy Spirit: filling him, guiding his words, and confirming the literal fulfillment of Jesus’ promise that His followers would speak by divine power.
