What Does “Life and Death Are in the Power of the Tongue” Mean in the Bible?

What Does “Life and Death Are in the Power of the Tongue” Mean in the Bible?

“Sticks and stones may break my bones, but words will never hurt me.” Maybe you’ve said it, but do you believe it? Someone revised this into, “Sticks and stones may break our bones, but words will break our hearts.”

Proverbs 18:21 says “Death and life are in the power of the tongue.” The tongue can be used as a weapon to harm and destroy or as a tool to build and heal. What kind of impact do your words have?

Our newspaper carried the tragic story of a teenaged girl who began an online relationship with an admirer in a cyberspace chat room. The boyfriend, who was really her neighbor posing as someone else, broke up with her and wrote that the world would be a better place without her. The girl read those words and killed herself.

When has an acid tongue burned you? Or kind words refreshed your soul? We’ve all wished we could retract a thoughtless jab or had the perfect word to say at the right time. The Bible tells us the types of words that bless and curse.

What traits differentiate a life-giving tongue from a destructive tongue?

Do my words build up or cut down?

Do my words build up or cut down?


Building words instruct, improve, build up, edify, affirm, or promote growth.

“Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen” (Ephesians 4:29 NIV).

Sincere compliments and words of affirmation strengthen people’s positive traits. God’s Word builds us up by telling us who we are in Christ and how to live victoriously.


In contrast, critical words judge and find fault. Theytear down, beat up, and focus on defects and inadequacies.

“With their words, the godless destroy their friends” (Proverbs 11:9 NLT).

A client tried to give her critical mother the perfect Christmas gift. With little money, she listed ten projects her mother wanted done and promised to complete them. When her mother opened her gift and read the list she said, “Is that all?” With three small words she crushed her daughter.

Do you want to be known as a problem identifier or an encourager? Criticism may come more easily than craftsmanship. Be a craftsman anyway.

Are my words loving or unwholesome?

Are my words loving or unwholesome?


Lovingwords reflect God’s nature. Love is the hallmark of a believer and the perfect regulator of the tongue (John 13:35; 1 Corinthians 13:1-3). Love seeks a person’s eternal best and tells the truth in a constructive way. It never flatters, but warns, confronts, and protects.

“Instead, we will speak the truth in love, growing in every way more and more like Christ, who is the head of his body, the church” (Ephesians 4:15, 25). 

“Love does no wrong to others, so love fulfills the requirements of God’s law” (Romans 13:10).

“An open rebuke is better than hidden love!” (Proverbs 27:5).

“Wounds from a sincere friend are better than many kisses from an enemy” (Proverbs 27:6)

“As iron sharpens iron, so a friend sharpens a friend” (Proverbs 27:17).

Check the motive behind what you want to say. Sincere love blesses people.


Unwholesomewords are the opposite of loving words. Theymake unfair comparisons. “Why can’t you be like…” They use people as a dumping ground for worry, needless chatter, and negative information. Such talk harms people’s mental and moral well-being.

Whereas love speaks the truth for the good of the hearer and shows respect, unwholesome words manipulate and use people and grieve the Holy Spirit (Ephesians 4:29-30). Discard this talk like overripe fruit.

“Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen” (Ephesians 4:29).

“A lying tongue hates its victims, and flattering words cause ruin” (Proverb 26:28).

“In the multitude of words sin is not lacking, but he who restrains his lips is wise” (Proverb 10:19).

“Take control of what I say, O Lord, and guard my lips” (Psalm 141:3).

“Do everything without grumbling or arguing” (Philippians 2:14).

A gossip betrays a confidence; separates close friends; keeps a quarrel going (Proverbs 11:13; 16:28; 26:20, 21)

Does my tongue encourage or ridicule?

Does my tongue encourage or ridicule?


Toencourage is to inspire with courage or hope, to hearten. Encouragement provides the home team advantage. It urges people to be brave and exercise their God-given gifts. It says “I believe in you. Through Christ you can do it. You’re not alone.”

We encourage people by showing respect for them, even when their opinions are different from ours. We listen and empathize instead ofminimizing the pain of those hurting.

“But encourage one another daily, as long as it is called ‘Today,’ so that none of you may be hardened by sin’s deceitfulness” (Hebrews 3:13). 

“Encourage the disheartened, help the weak, be patient with everyone” (1 Thessalonians 5:14).

Geese in flight honk to encourage the goose in front who breaks the resistance of the wind.My husband is my cheerleader. He encourages me to exercise my spiritual gifts even though they take time away from domestic responsibilities. Would those close to you call you a cheerleader?


Conversely, ridiculemocks, derides, taunts, and name-calls. Ridicule is a form of rejection and devalues people made in God’s image.

A friend’s family called her “Little Dummy” growing up. Name-calling is not funny to the one derided. Ridiculing words cloaked in a thin veil of “humor” still hurt. Even if you don’t mean ill, if the person is injured by them, your tongue has become a destructive weapon not a life-giving tool.

Ridicule can also take the form of making light of someone’s sorrow.

“Nor should there be obscenity, foolish talk or coarse joking, which are out of place, but rather thanksgiving” (Ephesians 5:4).  

“Like one who takes away a garment on a cold day, or like vinegar poured on a wound, is one who sings songs to a heavy heart”(Proverbs 25:20).

Before you ridicule someone, remember James 3:6 says destructive words are fueled by hell.

Is my tongue soothing or sharp?

Is my tongue soothing or sharp?


Soothing words heal. A quiet and gentle spirit is precious to God and doesn’t need to snap and yell.

“The soothing tongue is a tree of life, but a perverse tongue crushes the spirit” (Proverbs 15:4).

“A gentle answer turns away wrath, but a harsh word stirs up anger” (Proverbs 15:1).

“Through patience a ruler can be persuaded, and a gentle tongue can break a bone” (Proverbs 25:15).

“She opens her mouth in wisdom, and the teaching of kindness is on her tongue” Proverbs 31:26).

“And the Lord’s bond-servant must not be quarrelsome, but be kind to all, able to teach, patient when wronged, with gentleness correcting those who are in opposition; if perhaps God may grant them repentance leading to the knowledge of the truth” (2 Timothy 2:24, 25).

When we abide in Christ, we stay calm and composed. In quietness and trust we find strength (Isaiah 30:15).

Sharp words

Sharp words cut and slice like a chef’s knife. Sharp words include insults, jabs, and curse words usually spoken in anger and bitterness.

“You who practice deceit, your tongue plots destruction; it is like a sharpened razor” (Psalms 52:2)

“I am in the midst of lions; I am forced to dwell among ravenous beasts — men whose teeth are spears and arrows, whose tongues are sharp swords.” (Psalms 57:4).

Motivational speaker Jim Rohn said, “If it is not necessary to scold, it is necessary not to scold.” Save strong tones to sound the alarm and protect, not to harm and scar.

What power fuels my words — the Spirit or evil?

What power fuels my words — the Spirit or evil?

Spirit-filled words

Spirit-filled words provide the power and wisdom to harness the tongue. The Bible says, “No human being can tame the tongue. It is a restless evil, full of deadly poison” (James 3:8).

Self-effort can’t tame the tongue. Neither can good intentions. We need the power of God. And we have it!

Ephesians 5:17-20 commands us to be continually filled with the Holy Spirit. Our words reveal who controls our heart. A life filled with the Holy Spirit pours out blessing and thanksgiving. Spirit-filledlips make sweet music, instead of noisy gongs.

Jesus said, “For the mouth speaks out of that which fills the heart. The good man out of his good treasure brings forth what is good; and the evil man out of his evil treasure brings forth what is evil” (Matthew 12:34-35).

“But the Holy Spirit produces this kind of fruit in our lives: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control” (Galatians 5:22-23).

Present your tongue to God as an instrument of righteousness (Romans 6:13). Ask Him to fill you with His Spirit. Practice offering Him praise and thanksgiving (Psalm 34:1) and watch God infuse your tongue with life-giving power.

Spirit-filled lips bless God and people. Submit your heart to God and hand Him the reins to your tongue.

Evil-fueled words

The Scripture says a tongue not under the control of the Holy Spirit is a restless evil set on fire by hell and controlled by the evil one (James 3:6).

“The tongue also is a fire, a world of evil among the parts of the body. It corrupts the whole body, sets the whole course of one’s life on fire, and is itself set on fire by hell. It is a restless evil, full of deadly poison” (James 3:6, 8 NIV).

“But I tell you that every careless word that people speak, they shall give an accounting for it in the day of judgment. And I say to you that every careless word what men shall speak, they shall render account for it in the day of judgement. For by your words you shall be justified, and by you words you shall be condemned” (Matthew 12:36-37 NASB).

“But the things that come out of a person’s mouth come from the heart, and these defile them” (Matthew 15:18 NIV).

 “You let your mouth say anything evil.Your tongue plans deceit.You sit and talk against your own brother. You slander your own mother’s son. When you did these things, I remained silent. That made you think I was like you. I will argue my point with you and lay it all out for you to see” (Psalms 50:19-21).

I have a precious friend who radiates Jesus. She has blessed me in many ways with her prayers, encouragement, and insights from her walk with God. But she’ll tell you she used to have a “potty mouth.” When she gave her heart to Jesus, He transformed not only her heart but also her tongue.

The tongue is small but powerful. Unbridled it dispenses deadly poison. Bridled by the Holy Spirit it blesses, refreshes, and gives life. Is your tongue heaven’s tool or hell’s weapon? Give your heart and tongue to Jesus today.

“Take control of what I say, O Lord,and guard my lips” (Psalm 141:3).
