The tongue is very vital to our lives as human beings. As a physical organ, it gives us the ability to taste or speak. In the spiritual sense, the tongue controls our destiny, regardless of our status as Christians or unbelievers. In other words, the tongue is a very powerful instrument. According to Dag Heward-Mills we are unaware of the power our tongue possesses. It is dangerous to handle dynamite when you do not know what you are dealing with. Many Christians pass negative comments on their own lives, without knowing the far reaching effects. The tongue is full of poison which no man can tame, according to the Bible. It takes the Holy Spirit to help the believer control his tongue. In this book Dag Heward-Mills warns about the deadly poison like lies, flattery, profane language, tale-bearing, blasphemy, foolish talking, expressing doubt, slander, backbiting and murmuring your tongue can create.
