“And the tongue is a fire, a world of iniquity. The tongue is so set among our members that it defiles the whole body, and sets on fire the course of nature; and it is set on fire by hell.” James 3:6-7
Words give expression to the disposition of the heart. Eventually, not always immediately, the mouth will be engaged in speaking the truest feelings that reside deep within the soul. It is never a matter of merely guarding your words in order to sound off appropriate expressions. The issue must be addressed at its root. From the abundance of the heart the mouth speaks. When the heart is rightly governed, the tongue is sure to follow. But what comes out of a man defiles him for when he speaks he spreads the contagion to others. You are responsible for how you influence the people with whom you come in contact. Not just your body, but the whole body is defiled and set to follow the course of nature. It is what you have heard in the past that has influenced your future. Sweet water must flow from a pure fountain for no bitter water is contained there. God gave you a new heart in order for His Word to be given expression through a new creature. Now guard your heart so that the old references are no longer your conversation.
