How powerful are the words we speak?

The tongue has the power of life and death, and those who love it will eat its fruit. – Proverbs 18:21

The words from Proverbs remind us that the words we speak are, indeed, powerful!

Our words, whether spoken or written, have the power of life (to lift someone up) or death (to tear someone down).

Once the damage of tearing someone down with our words has been done there’s no turning back. They can forgive but they’ll never be able to forget, and there’s no doubt this student will always remember her mother’s word.

The words of the reckless pierce like swords, but the tongue of the wise brings healing. – Proverbs 12:18

The words you say today can impact someone for years to come, which is why we must be careful and intentional about the words we speak.

What did Jesus say about the words we speak?

As you’ll see in these Bible verses, the words that come out of our mouth are important.

Listen to the words of Jesus Himself as He shares about the power of words.

“A good man brings good things out of the good stored up in his heart, and an evil man brings evil things out of the evil stored up in his heart. For the mouth speaks what the heart is full of.” – Luke 6:45

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

“But I tell you that everyone will have to give account on the day of judgment for every empty word they have spoken. For by your words you will be acquitted, and by your words you will be condemned.” – Matthew 12:36-37

“What goes into someone’s mouth does not defile them, but what comes out of their mouth, that is what defiles them.” – Matthew 15:11

Bible verses on the power of our words.

If you’re wondering what the Bible says about the way we speak and the power of spoken words, look no further than these scriptures.

Let these Bible verses about wise words penetrate deep into your heart! As you’ll see, the book of Proverbs has a lot to say about the words that come out of our mouth.



Proverbs 15:1

A gentle answer turns away wrath, but a harsh word stirs up anger.”

Proverbs 15:2

The tongue of the wise adorns knowledge, but the mouth of the fool gushes folly.

Proverbs 17:27-28

Proverbs 12:25

Proverbs 10:11

The mouth of the righteous is a fountain of life, but the mouth of the wicked conceals violence.

Proverbs 4:24

Keep your mouth free of perversity; keep corrupt talk far from your lips.



If I could sum up what the Bible says about the words we speak in one verse, I think Ephesians 4:29 would be it.

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.

The words we speak tell a story!

The tongue also is a fire, a world of evil among the parts of the body…With the tongue we praise our Lord and Father, and with it we curse human beings, who have been made in God’s likeness. Out of the same mouth come praise and cursing. My brothers and sisters, this should not be. Can both fresh water and salt water flow from the same spring? My brothers and sisters, can a fig tree bear olives, or a grapevine bear figs? Neither can a salt spring produce fresh water. – James 3:6a, 9-10

Jackie Hill Perry, in her devotional Upon Waking, shares this very powerful truth regarding what James says about the words that come out of our mouth!

“The way we speak to and about people tells a story. If we understand everyone, friend and foe, neighbor and nuisance, as made in the likeness of God, the words we say should be tempered by that truth.

Every single person we will ever converse with, both sinner and saint, bears the image of God; and for that reason, each person is worthy of honor.”
