What Does the Bible Say About Cursing?

Scripture reveals that our words reveal what's in our hearts, and cursing contradicts both who God is and who we claim to be as His followers.

Scripture on Cursing

Ephesians 4:29 New Testament
"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."
James 3:9-10 New Testament
"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."
Proverbs 13:3 Old Testament
"Those who guard their lips preserve their lives, but those who speak rashly will come to ruin."
Colossians 3:8 New Testament
"But now you must also rid yourselves of all such things as these: anger, rage, malice, slander, and filthy language from your lips."
Proverbs 29:11 Old Testament
"Fools give full vent to their rage, but the wise bring calm in the end."
The Bottom Line
Your mouth is a mirror of your spirit — cursing exposes a heart that hasn't been fully surrendered to Jesus' transformation.
Try Today

The next time you feel the impulse to curse, pause for three seconds and speak a simple, honest phrase instead — 'That's frustrating' or 'I need help here' — and notice how it changes what you feel.

Prayer

Jesus taught us that 'out of the abundance of the heart the mouth speaks' (Matthew 12:34) — so we can bring our mouths and hearts to the Father in prayer.

Father, I confess that my words sometimes don't match who You are or who You're making me to be. The impulse to curse comes from frustration, anger, or carelessness I haven't surrendered to You. I want my mouth to build people up, not tear them down. Change what's in my heart so that what comes out of my mouth honors You. Help me pause, think, and speak with intention today. In Jesus' name, Amen.
