What does the Bible say about the words we speak?
The Bible treats the tongue as small but powerful — able to bless or destroy — and calls us to speech that is true, gracious, and life-giving.
James compares the tongue to a tiny rudder that steers a great ship and a small flame that sets a forest ablaze. “The tongue has the power of life and death” (Proverbs 18:21).
Scripture warns against gossip, slander, lying, and careless words, for “out of the overflow of the heart the mouth speaks.” Our words reveal what is really inside us.
The goal is not silence but redeemed speech: “Let no unwholesome talk come out of your mouths, but only what is helpful for building others up.” Grace-filled words are a mark of a changed heart.
