Lesson on avoiding deceitful speech?
What can we learn from Psalm 36:3 about avoiding deceitful speech?

Setting the Scene

Psalm 36 contrasts the ways of the wicked with the steadfast love of God. Verse 3 pinpoints how evil shows up in everyday conversation.

“​The words of his mouth are wicked and deceitful; he has ceased to be wise and well-doing.” (Psalm 36:3)


What the Verse Reveals

• Wicked words flow out of a heart already bent toward evil; speech is a barometer of the inner life (Matthew 12:34).

• Deceit replaces wisdom. When a person stops speaking truth, genuine wisdom and upright action dry up as well (James 3:13–17).

• The decline is progressive: first abandoning wisdom, then abandoning all “well-doing.” The tongue leads the life (James 3:2–6).


Practical Lessons for Guarding Our Tongues

1. Recognize the Link between Speech and Character

– Deceitful words advertise a deeper moral problem (Proverbs 4:24).

– Guarding the tongue begins with guarding the heart (Proverbs 4:23).

2. Choose Wisdom over Craftiness

– True wisdom and dishonest speech cannot coexist (Proverbs 8:7).

– Ask God for wisdom daily (James 1:5); wisdom yields truthful, peaceable words (James 3:17).

3. Love What God Loves, Hate What He Hates

– “Lying lips are detestable to the LORD” (Proverbs 12:22).

– Align your affections with His, and deceit will lose its appeal.

4. Replace Deceit with Edifying Truth

– “Therefore each of you must put off falsehood and speak truthfully” (Ephesians 4:25).

– Intentionally speak words that build up (Ephesians 4:29).

5. Cultivate Daily Self-Examination

– Pray Psalm 139:23–24 to expose hidden falsehood.

– Confess quickly when deceit slips out (1 John 1:9).


Supporting Scriptures

Psalm 34:13 – “Keep your tongue from evil and your lips from speaking deceit.”

Colossians 3:9 – “Do not lie to one another, since you have taken off the old self with its practices.”

Proverbs 16:13 – “Righteous lips are a king’s delight; he loves those who speak honestly.”


Steps to Apply Today

• Start the day by reading a Proverb about speech; let it set the tone.

• Before speaking, ask: “Is it true? Is it loving? Is it necessary?”

• Memorize Psalm 36:3 to remind yourself of the cost of deceit.

• If tempted to shade the truth, pause, breathe, and rephrase honestly.

• Celebrate victories—every time you choose truth, you grow in wisdom and “well-doing.”


Encouragement to Persist

God’s grace trains us to renounce deceit and live upright, tongue and all (Titus 2:11-12). Keep leaning on that grace, and your speech will increasingly mirror the truthful character of the One you follow.
