According to the Bible, though our tongues are small they have the power to bring death to a life as well as to preserve and save it (Proverb 18:21). Actually, the results of a study show that nerves in the speech-control center of our brains has a managing influence over all other nerve systems. For instance, if you say "I'm getting weak," you will really get weak. People say that you can change your life if you change your words. In a critical situation beyond your ability and control there is nothing more important than a person's positive confession of faith of his believing in and his dependence on God. It is because the confession of faith that you can make has the power to make the impossible possible.
