How can we warn others like Peter?
In what ways can we actively warn others, as Peter did in Acts 2:40?

The Verse at the Heart of Our Study

Acts 2:40: “With many other words he testified, and he urged them, ‘Be saved from this corrupt generation.’”


Why Warning Matters

• Scripture presents warning as a loving duty (Ezekiel 3:17–19; Proverbs 24:11).

• The gospel itself contains both promise and peril (John 3:16–18).

• Believers know the coming judgment and are compelled to persuade others (2 Corinthians 5:11).


Ways We Can Actively Warn Others

1. Speak the whole gospel—not just comfort but crisis

• Declare God’s holiness, human sin, Christ’s atonement, and the need to repent (Acts 17:30).

• Avoid watering down sin; Peter called his hearers a “corrupt generation.”

2. Urge personal response

• Use clear, second-person language: “Be saved,” “Turn,” “Repent.”

• Follow the pattern of 2 Timothy 4:2—“reprove, rebuke, and encourage.”

3. Appeal to Scripture as final authority

• Quote and explain passages so listeners hear God’s voice, not merely opinion (Hebrews 4:12).

• Peter anchored his sermon in Joel and the Psalms (Acts 2:16–35); we can do the same.

4. Expose the danger of remaining in sin

• Warn of wrath (John 3:36), coming judgment (Acts 17:31), and eternal separation (Revelation 20:11-15).

• Couple warning with the mercy offered in Christ (Romans 5:8-9).

5. Model sincerity and urgency

• Peter “testified” and “urged”; Paul warned “with tears” (Acts 20:31).

• Let tone and body language show genuine concern, not condemnation.

6. Live a credible, holy life

• A consistent walk backs up urgent words (1 Peter 3:15-16).

• Repent quickly, pursue purity, and practice visible love (Philippians 2:15-16).

7. Leverage relationships and everyday moments

• Family gatherings, work breaks, community service—places Peter’s listeners came from all over Jerusalem; our circles are just as strategic.

• Use stories, personal testimony, and current events to connect truth to life (Psalm 66:16).


Practical Tips for Everyday Conversations

• Carry a small Bible or app; read a verse aloud rather than paraphrasing.

• Ask permission to share: “May I show you what Jesus says about this?”

• Keep tracts or short booklets handy; leave them with a brief verbal appeal.

• Follow up—text a verse, invite to coffee, or offer a ride to church.

• Pray privately for courage before speaking and for receptivity afterward (Colossians 4:3-4).


Courage and Compassion Together

Warning is not optional but essential. When we combine unwavering truth with Christ-like compassion, we stand in Peter’s footsteps—pleading, “Be saved from this corrupt generation,” while pointing unmistakably to the only Savior who can rescue and restore.
