You have the power to change someone’s life simply by the words that you speak. Proverbs says, “Death and life are in the power of the tongue” (Proverbs 18:21 NKJV). That’s why Paul urges you and me to be careful. “When you talk, do not say harmful things, but say what people need—words that will help others become stronger” (Ephesians 4:29).
Your words are to their soul what a vitamin is to their body. If you had food and saw someone starving, would you not share it? If you had water and saw someone dying of thirst, would you not give it? Of course you would. Then won’t you do the same for their hearts? Your words are food and water. Do not withhold encouragement from the discouraged. Speak words that make people stronger. Believe in them as God has believed in you.
