It is a small rudder in a boatman's hand that leads a ship safely to a destination in a boundless ocean. In this way, the tongue, though it is a very little part of our body, can cause people to die or to live. That's because even one word can give hope to others. On the contrary, it can hurt others' hearts deeply. We must know that success and failure in our life depends on whether we encourage ourselves as well as others with affirmative words or disparage with negative words. And we should bear good fruit with affirmative words all the time.
"Death and life are in the power of the tongue, and those who love it will eat its fruit." (Proverbs 18:21)
