What Does the Bible Say About the Tongue?
The power of words — for life and death — and how to guard them.
The Bible says the tongue carries enormous power — death and life are in its power (Proverbs 18:21) — and calls us to tame it, speaking only what edifies (Ephesians 4:29) and asking God to guard our mouths (Psalm 141:3).
Small but powerful
James compares the tongue to a tiny rudder that steers a great ship and a small spark that sets a forest ablaze. No other small thing does so much good or damage. Words can bless or wound, heal or destroy.
Death and life are in the power of the tongue: and they that love it shall eat the fruit thereof.
Death and life are in the power of the tongue.
Even so the tongue is a little member, and boasteth great things. Behold, how great a matter a little fire kindleth!
The tongue is a little member, and boasteth great things.
Words that give life
Scripture calls us to speak what builds up and ministers grace, to be swift to hear and slow to speak, and to pray for God's help in guarding the mouth. Gentle, gracious, true words are a form of love.
Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
Let no corrupt communication proceed out of your mouth, but that which is good.
Set a watch, O LORD, before my mouth; keep the door of my lips.
Set a watch, O LORD, before my mouth; keep the door of my lips.
