Pro 15:1 A soft answer turneth away wrath: but grievous words stir up anger.
Dealing with anger is a major lesson in life to be learned, both our own anger and anger of others. Anger is often expressed in words, and also is often provoked by our words. Part of dealing with anger is learning to control our mouth. Learning to speak calmly, with reason and kindness, will help to diffuse anger, much like throwing water on a fire. However, responding with bitter hateful words will lead to more anger, much like throwing gasoline on the fire. Lets learn to be firemen, quenching the flames of anger by our words.
