Deceit is in the hearts of those who devise evil
This phrase highlights the intrinsic connection between deceit and evil intentions. Biblically, the heart is often seen as the center of one's being, encompassing thoughts, emotions, and will. Jeremiah 17:9 describes the heart as deceitful above all things, emphasizing the natural inclination towards sin without divine intervention. The concept of devising evil is seen throughout Scripture, such as in Genesis 6:5, where God observes the wickedness of humanity before the flood. Historically, deceit has been a tool for manipulation and control, as seen in the actions of figures like Jezebel (1 Kings 21). Theologically, this phrase underscores the need for a transformed heart, as promised in Ezekiel 36:26, where God offers a new heart and spirit to His people.

but the counselors of peace have joy
In contrast, this phrase presents a positive outcome for those who pursue peace. Counselors of peace are individuals who seek reconciliation and harmony, aligning with the biblical call to be peacemakers (Matthew 5:9). The joy mentioned here is not merely an emotional state but a deep-seated contentment and fulfillment that comes from living in accordance with God's will. This joy is a fruit of the Spirit (Galatians 5:22) and is often associated with righteousness and wisdom (Proverbs 3:13-18). Culturally, peace was a highly valued virtue in ancient Israel, often linked with the concept of shalom, which encompasses wholeness and well-being. Theologically, Jesus Christ is the ultimate Counselor of Peace, as prophesied in Isaiah 9:6, and His teachings and sacrifice bring true joy and reconciliation with God.

What Does Proverbs 12:20 Mean

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.

(20) Deceit is in the heart . . .--Those who plot and devise evil against others begin by deceiving them, and end by deceiving themselves also; whereas the "counsellors of peace," who seek the good of their neighbours, bring joy to them and to themselves also through the satisfaction derived from a good conscience.

Verse 20. - Deceit is in the heart of them that imagine evil; i.e. that give evil advice; such are treacherous counsellors, and their advice can only work mischief, not joy and comfort (see on Proverbs 3:29). But to the counsellors of peace (health and prosperity) is joy. They who give wholesome advice diffuse joy around. Vulgate, "Joy attends them;" Septuagint, "They shall be glad;" but the original signifies rather to cause joy than to feel it. Parallel Commentaries ...
