Do you think that someone’s words are a true indicator of their heart? By your words you shall be justified or condemned. Yet thoughts precede words and are a more certain measure.
The thoughts of others are not available to you, but your own are ever with you. Are you careful to filter your thoughts realizing that not all of them are suitable for speaking aloud? You are wise, for only a fool utters all his mind. Yet it is possible to take control of your thoughts the same way, for I have enabled you and commanded you to take every thought captive. If you are careful in what you think you won’t have to be as careful in what you say.
