"He who guards his mouth and his tongue, Guards his soul from troubles." Proverbs 21:23

How often do we say things in anger, pride, gossip, spite, frustration and disobedience; then in a moment (sometimes longer) we regret what came out of our mouth? The dreadful words are forever out and cannot be recaptured. Scripture has much to say about the mouth and the tongue, for uncontrolled it is evil and destructive. Let's look at some of these verses.

"The one who guards his mouth preserves his life; The one who opens wide his lips comes to ruin." Proverbs 13:3

"A man's [moral] self shall be filled with the fruit of his mouth; and with the consequence of his words he must be satisfied [whether good or evil].
Death and life are in the power of the tongue, and they who indulge in it shall eat the fruit of it [for death or life].
Proverbs 18:20-21 The Amplified Bible

"Whoever guards his mouth and tongue
Keeps his soul from troubles." Proverbs 21:23

Jesus when talking to the Pharisees in Matthew 12:36-37 said, "And I say to you, that every careless word that men shall speak, they shall render an account for it in the day of judgment. For by your words you shall be justified, and by your words you shall be condemned." (Be sure to read the whole account Vs. 22-37)

James 3:2-12 is another portion of Scripture concerning the tongue that gives us a very clear understanding of the tongue. Again, I urge you to read the whole account.
Vs. 8-10 says,
"But no one can tame the tongue, it is a restless evil and full of deadly poison. With it we bless our Lord and Father, and with it we curse men, who have been made in the likeness of God; from the same mouth come both blessing and cursing. My brethren, these things ought not to be this way."

We who belong to the Lord have the Spirit of Truth dwelling within each of us and it is He who tames the tongue as we yield to Him to guide and direct.
There is a verse of Scripture that is good to write in your heart for just those times when you are tempted to say some evil hurtful thing. As we daily make this verse a matter of prayer, we have in the moment of temptation, a Spiritual caution! Now our focus can turn to Him Who is able to keep us from wrong. I must confess this verse is an earnest part of my daily prayers.

"Set a guard, O LORD, over my mouth;
Keep watch over the door of my lips." Psalm 141:3

Lord God, our desire is that the fruit of our tongue and lips would be ever pleasing to You.  Amen
