Proverbs 15:2: Power of words?
What does Proverbs 15:2 teach about the power of our words?

Scripture Focus

“The tongue of the wise commends knowledge, but the mouth of fools spouts folly.” (Proverbs 15:2)


Key Observations

• Two kinds of speech are contrasted: wise words that “commend” (literally, make attractive or beautiful) true knowledge, and foolish words that gush out folly.

• The verse underscores that speech is never neutral; it either elevates truth or multiplies error.

• Because Scripture is wholly accurate, this contrast is a reliable, timeless principle, not merely an ancient proverb.


The Power of Wise Words

• Wise speech highlights, explains, and spreads knowledge that aligns with God’s revealed truth.

• When our words are grounded in Scripture, they act like a spotlight, helping others see God’s wisdom clearly (Psalm 119:130).

• Wise language builds up, bringing grace to those who hear (Ephesians 4:29).


The Peril of Foolish Words

• “Spouts” pictures a reckless gush—speech poured out without restraint or discernment.

• Foolish talk misleads, wounds, and fuels sin (James 3:5–6).

• Unlike wise words, foolish speech doesn’t merely lack value; it actively propagates error and harm.


Why This Matters

Proverbs 18:21 reminds us, “Death and life are in the power of the tongue.” Our words carry real spiritual weight.

• Jesus said we will give account for “every careless word” (Matthew 12:36). The stakes are eternal.

• Words shape hearts and destinies; therefore, mastering the tongue is a mark of true maturity (James 3:2).


Practical Takeaways

– Pause before speaking; ask whether your words will “commend knowledge.”

– Saturate your mind with Scripture so your tongue naturally echoes truth (Colossians 3:16).

– Replace reactionary talk with thoughtful, edifying responses (Proverbs 15:28).

– Seek accountability; invite trusted believers to correct unwise speech (Proverbs 27:6).

– Celebrate and reinforce wise words you hear in others, cultivating a culture of godly speech.


Cautions Against Foolish Speech

• Avoid rumor, slander, and coarse joking; each pours out folly (Ephesians 5:4).

• Guard against venting anger unchecked; “A fool’s lips invite a beating” (Proverbs 18:6).

• Recognize that social media can amplify foolish speech; exercise the same restraint online as in person.


Encouragement to Speak Life

• Let your mouth be a fountain of refreshment, offering “gracious words” that are “sweet to the soul” (Proverbs 16:24).

• Trust the Holy Spirit to guide your tongue; He empowers believers to speak with boldness and clarity (Acts 4:31).

• Every conversation is an opportunity to showcase the goodness and wisdom of God, turning ordinary moments into eternal investments.
