God instructs us to choose the words we speak wisely. As we are diligent to teach our children God’s Word regarding this and show them by our example, they will grow up understanding that words can either bring healing or harm. Each person chooses.
Proverbs 16: 23-24 The heart of the wise teacheth his mouth, and addeth learning to his lips. Pleasant words are as an honeycomb, sweet to the soul, and health to the bones.
