What does Proverbs 12:20 mean?
What is the meaning of Proverbs 12:20?

Deceit in the heart

“Deceit is in the hearts …” (Proverbs 12:20a)

• Deceit isn’t merely an occasional slip; it lives “in the hearts,” showing a settled inner condition (Jeremiah 17:9; Psalm 36:1–4).

• Scripture pictures the heart as the control center of thoughts, motives, and decisions (Proverbs 4:23). When deceit occupies that center, every plan that flows outward is poisoned.

• The Lord hates “a lying tongue” and “a heart that devises wicked schemes” (Proverbs 6:16–18). From Eden onward, deception has always been Satan’s signature, and those who harbor deceit align themselves with that dark pattern (John 8:44).


Those who devise evil

“… of those who devise evil …” (12:20a)

• “Devise” points to deliberate, calculated plotting, not impulsive wrongdoing. Compare Psalm 140:2, where evil men “devise mischief in their hearts.”

• Typical forms today include:

– Manipulating others for personal gain.

– Setting traps to discredit someone’s reputation.

– Spreading half-truths or rumors to tilt outcomes.

– Crafting policies or strategies that sacrifice morality for profit or power.

• God warns that such scheming will rebound on the plotter (Proverbs 26:27; Esther 7:10).


But: the great contrast

“But …” (12:20b)

• Scripture frequently uses a stark “but” to pivot from darkness to light (Ephesians 2:4; Psalm 73:26).

• Here the Spirit sets two groups in opposition: devisers of evil versus counselors of peace. There is no neutral middle; every heart either nurtures deceit or promotes peace.


Counselors of peace

“… but the counselors of peace …” (12:20b)

• “Counselors” suggests people who influence, advise, and steer conversations. Their goal is “peace,” meaning wholeness, harmony, and restored relationships (Romans 12:18).

• Characteristics of such counselors:

– Speak truth lovingly (Ephesians 4:15).

– Seek reconciliation over revenge (Matthew 5:9; 2 Corinthians 5:18).

– Value wisdom from above, which is “peace-loving, considerate, submissive, full of mercy” (James 3:17).

– Model gentle answers that turn away wrath (Proverbs 15:1).

• Their influence reaches homes, churches, workplaces, and communities, fostering environments where righteousness can flourish (Proverbs 11:10).


Have joy

“… have joy.” (12:20b)

• Joy is both the present experience and the lasting reward of peace-making. Jesus promised, “Blessed are the peacemakers” (Matthew 5:9).

• Joy springs from:

– A clear conscience before God (Romans 15:13).

– Relationships marked by trust instead of suspicion (Proverbs 16:7).

– The indwelling Spirit who produces joy as fruit (Galatians 5:22).

• While deceit enslaves its owner in fear of exposure, peace-counseling sets hearts free to rejoice (Psalm 97:11).


summary

Proverbs 12:20 draws a sharp line: hearts harboring deceit scheme for evil, but those who counsel peace live in God-given joy. Deception corrodes from the inside out and ultimately backfires. Peace-making, by contrast, aligns us with the Lord’s own character and opens the door to enduring gladness. Choose the path of honest, peace-seeking counsel and enter the joy that God delights to give.
