The condition of your heart will determine the content of your mouth. You can only keep quiet on what you really think and feel for so long until the volcano erupts and someone eavesdrop’s in on what is really going on in your personal world. If you want to change the content of your talk, you must allow God to change the theme of your heart. When God changes your heart, his desires become your desires, his thoughts become your thoughts, his ways become your ways and his words become your words.
Charles Spurgeon once said, “The burning heart will soon find for itself a flaming tongue.” When your heart burns for God, your words will ignite and inspire passion in others.
