You cannot talk without your tongue. It helps you to express yourself as well as eat, drink, and breath. Once the tongue is taken off, you lose total control of your body, and you will need assistance to get things done until you can start all over again.
The same tongue is vital for your life. Therefore, the question is, what do you do with it? What are the words that come out of your mouth? Do they edify others or bring them down? Do they encourage you or aid in further destruction of your soul? If you cannot train your tongue in the same way you teach yourself to drive a car, then what will happen is that it (tongue) will drive you down until you face a think wall. Be careful.
