The Bible commands believers to let their speech be wholesome and edifying, warning that the tongue has power for both life and death.
The Bible commands believers to let their speech be wholesome and edifying, warning that the tongue has power for both life and death.
"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." — Ephesians 4:29 (KJV)
The Biblical Context
Scripture takes speech seriously. The third commandment forbids taking God's name in vain (Exodus 20:7). Ephesians 4:29 instructs, 'Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying.' Colossians 3:8 tells believers to 'put off... filthy communication out of your mouth.' James 3:9-10 warns against the contradiction of blessing God and cursing people made in His image. Proverbs 18:21 declares, 'Death and life are in the power of the tongue.' Jesus taught that 'every idle word that men shall speak, they shall give account thereof in the day of judgment' (Matthew 12:36). The Bible consistently calls believers to speech that honors God, builds others up, and reflects the transformed heart within.
