I urge you to use words with restraint. Misusing words is one of the easiest ways to sin—and one of the deadliest. In fact, the tongue is a fire that corrupts the whole person, sets the whole course of his life on fire, and is itself set on fire by hell. You would be wise to follow the example of David, who wrote: Set a guard, O Lord, over my mouth; keep watch over the door of my lips. Controlling your tongue is so difficult that you cannot do it without massive help.
Actually, I want to help you control not only your spoken words but also your thoughts. The contents of your thoughts have an enormous influence on your health and well-being. Many people are depressed or anxious because their thinking is so distorted and unbiblical. If this problem remains uncorrected, it can lead to a breakdown of health. However, Scripture provides correction: Pleasant words are sweet to the soul and healing to the bones. When My Spirit is controlling your thoughts and words, both your soul and your body will flourish. Ask the Spirit to think and speak through you. Since He lives in your innermost being, He can easily influence you, but He waits to be invited. The more you invite Him into your life, the healthier and happier you will be. Your words will be pleasant—blessing not only you but also those around you.
A man of knowledge uses words with restraint, and a man of understanding is even-tempered.
~ Proverbs 17:27
The tongue also is a fire, a world of evil among the parts of the body. It corrupts the whole person, sets the whole course of his life on fire, and is itself set on fire by hell.
~ James 3:6
Set a guard, O Lord, over my mouth; keep watch over the door of my lips.
~ Psalm 141:3 [NKJV]
Pleasant words are a honeycomb, sweet to the soul and healing to the bones.
~ Proverbs 16:24
