1. Highlight the Value of Humility

When someone thinks they know everything, it’s often pride talking. Rather than meeting arrogance with more of the same, encourage a humble heart. After all, “God opposes the proud but gives grace to the humble” (James 4:6). A gentle, respectful response can open the door for meaningful dialogue.

2. Ask Thoughtful Questions

Sometimes, there’s wisdom in letting the other person see for themselves where their knowledge might be lacking. Gracefully ask questions that prompt them to explain and expand on their views. “A man of understanding delights in counsel” (Proverbs 1:5), so offer insightful queries that encourage deeper reflection.

3. Affirm Their Desire to Learn

People who claim to know it all may be seeking validation. Instead of dismissing them outright, acknowledge their love for knowledge while pointing them to a better way. “Knowledge puffs up, but love builds up” (1 Corinthians 8:1). Let them see you appreciate their curiosity while gently reminding them that love should be the heartbeat of every conversation.

4. Offer Respectful Corrections

Stating hard facts works best when wrapped in kindness. “Let your speech always be gracious, seasoned with salt” (Colossians 4:6). As you correct misunderstandings, make your tone one that reflects patience and compassion, rather than superiority.

5. Steer the Conversation to Something Bigger

Those who boast about their own insight can easily forget how small we all are in the grand scheme of things. Remind them how “the heavens declare the glory of God; the skies proclaim the work of His hands” (Psalm 19:1). Pointing to something greater than ourselves helps shift focus from our limited understanding to a more awe-inspiring perspective.

6. Draw Attention to Genuine Wisdom

Real wisdom isn’t about having all the answers, but recognizing the best Source of truth. “If any of you lacks wisdom, he should ask God, who gives generously to all” (James 1:5). Invite your friend to look beyond mere human knowledge and seek guidance that transcends our own limitations.

7. Demonstrate Empathy

Sometimes, a know-it-all attitude hides insecurities. Showing empathy can soften hearts. “Bear one another’s burdens, and in this way you will fulfill the law of Christ” (Galatians 6:2). Compassion can weave understanding into the conversation, helping you both grow closer rather than drifting apart.

8. Champion the Virtue of Listening

Listening is a powerful way to connect with others and diffuse tension. It affirms that you value the other person, even when you disagree. Remember that “everyone should be quick to listen, slow to speak, and slow to anger” (James 1:19). By truly hearing them out, you may find common ground or a path toward a peaceful resolution.

9. Emphasize That We’re All Learning

None of us have arrived at perfect knowledge, and recognizing that can dissolve arrogance. “For now we see only a reflection as in a mirror; then we shall see face to face” (1 Corinthians 13:12). Gently point out that all of us, no matter how informed, are still in the process of learning and growing.

10. Encourage a Heart That Seeks Truth

Ultimately, inspire your friend to keep seeking. Genuine truth carries the power to transform far more than head knowledge alone. “In Christ are hidden all the treasures of wisdom and knowledge” (Colossians 2:3). Let your conversations be driven by a passion for truth, undergirded by humility and genuine love.
