Proverbs 18:21 confirms this:
This is further seen in Matthew 18:18, which proclaims:
These verses prove how much good or bad our tongues (words) can do. Mind you! They all come from the heart!
This power and responsibility is discussed several times in the Bible.
Here are 17 things the Bible says about using, and the repercussions of misusing this power.
1. “Whoever guards his mouth preserves his life; he who opens wide his lips comes to ruin.” Proverbs 13:3
2. “Let no corrupting talk come out of your mouths, but only such as is good for building up, as fits the occasion, that it may give grace to those who hear.” Ephesians 4:29
3. “A brother who has been insulted is harder to win back than a walled city, and arguments separate people like the barred gates of a palace.” Proverbs 18:19
4. “The words of a good person are like pure silver, but an evil person’s thoughts are worth very little.” Proverbs 10:20
5. “Without wood, a fire will go out, and without gossip, quarreling will stop.” Proverbs 26:20
6. “Your own soul is nourished when you are kind, but you destroy yourself when you are cruel.” Proverbs 11:17
7. “Do not repay evil with evil or insult with insult. On the contrary, repay evil with blessing, because to this you were called so that you may inherit a blessing.” 1 Peter 3:9
8. “Kind words are like honey – sweet to the soul and healthy for the body.” Proverbs 16:24
9. “But what comes out of the mouth proceeds from the heart, and this defiles a person.” Matthew 15:18
10. “I tell you, on the day of judgment people will give account for every careless word they speak.” Matthew 12:36
11. “For by your words you will be justified, and by your words you will be condemned.” Matthew 12:37
12. “But now you must put them all away: anger, wrath, malice, slander, and obscene talk from your mouth.” Colossians 3:8
13. “If anyone thinks he is religious and does not bridle his tongue but deceives his heart, this person’s religion is worthless.” James 1:26
14. When we put bits into the mouths of horses to make them obey us, we can turn the whole animal. Or take ships as an example. Although they are so large and are driven by strong winds, they are steered by a very small rudder wherever the pilot wants to go. Likewise, the tongue is a small part of the body, but it makes great boasts. Consider what a great forest is set on fire by a small spark. The tongue also is a fire, a world of evil among the parts of the body. It corrupts the whole body, sets the whole course of one’s life on fire, and is itself set on fire by hell.” James 3:3-6
15. “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. Can both fresh water and salt water flow from the same spring? My brothers and sisters, can a fig tree bear olives, or a grapevine bear figs? Neither can a salt spring produce fresh water.” James 3: 9-12
16. “Do you see a man who is hasty in his words? There is more hope for a fool than for him.” Proverbs 29:20
17. “Let your speech always be gracious, seasoned with salt, so that you may know how you ought to answer each person.” Colossians 4:6
And we pray:
LORD, tame my heart. By Your esteemed, immeasurable grace cause me to plant fields of peace and Love with my tongue. For out of the heart a tongue flows. My words define me, as Your Word is You – Jesus, Hallelujah!!! Father, today and always fill my heart that by your grace, I may overflow in Jesus’ name, Amen.
