Our words can elevate and encourage others, or discourage, even crush them.  Our words have power, far beyond what we usually realize.  Pivotal points in your life likely were due to the words of love and encouragement or harsh criticisms of others.  Citing scriptures and examples, Martin Tanner encourages us to use our words for good and to choose them carefully.  In so doing, we can be a little bit like God and Jesus, helping others with our words.
