What does the Bible say about the words that come out of your mouth?

Opinions, social media posts, texts, and constant communication - the words we speak often feel like fleeting echoes. But the Bible paints a very different picture—one where our words carry weight, power, and eternal significance. Scripture doesn’t just caution us about what we say; it invites us to see our speech as a reflection of our hearts and a tool for either healing or harm.

The Power of the Tongue

The Bible is clear: our words can shape reality.

• Proverbs 18:21 says, “Death and life are in the power of the tongue, and those who love it will eat its fruit.” 

  This verse reminds us that speech isn’t neutral—it either builds up or tears down.

  
  

• James 3:5-6 compares the tongue to a spark that can set a forest ablaze.

  A small word can ignite conflict, but it can also spark hope.

  
  

Guarding Our Mouths

Wisdom begins with restraint. The Bible urges us to be intentional with our speech.

• Proverbs 21:23: “Whoever keeps his mouth and his tongue keeps himself out of trouble.”

• Psalm 141:3: “Set a guard, O Lord, over my mouth; keep watch over the door of my lips.” 

  
  

  This is a prayer worth echoing daily.

• Ecclesiastes 5:2: “Do not be quick with your mouth… God is in heaven and you are on earth, so let your words be few.”

Words Reflect the Heart

Jesus taught that what comes out of the mouth reveals what’s inside.

• Matthew 12:34: “For out of the abundance of the heart the mouth speaks.”

• Luke 6:45: “A good man brings good things out of the good stored up in his heart… for the mouth speaks what the heart is full of.”

Our speech is a mirror. If we want to change our words, we must first examine our hearts.

Speaking Life and Grace

The Bible encourages us to use our words to uplift and encourage.

• Ephesians 4:29: “Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up.”

• Proverbs 16:24: “Gracious words are a honeycomb, sweet to the soul and healing to the bones.”

• Colossians 4:6: “Let your conversation be always full of grace, seasoned with salt.”

  
  

Accountability and Purpose

Words aren’t just casual—they’re accountable.

• Matthew 12:36: “I tell you, on the day of judgment people will give account for every careless word they speak.”

• James 1:19: “Everyone should be quick to listen, slow to speak and slow to become angry.”

God calls us to be stewards of our speech, using it to reflect His love and truth.

The Bible doesn’t just tell us to “watch our mouths”—it invites us to transform them. Our words can be instruments of peace, vessels of truth, and reflections of grace. So the next time you speak, ask yourself: Is this building up or tearing down? Is this truth or just noise? Is this love or something less?

Let’s choose words that heal, inspire, and honour the One who gave us the gift of speech.
