Words are available to you as a result of what you are thinking, seeing or feeling. They are a reflection of what is in your heart. As Jesus said "...out of the abundance of the heart the mouth speaks." (Matt. 12:34). You can use words to bless or you can use words to curse. Depending on the content and state of your heart (pure and innocent or full of hate and contempt) the words you utter from the depth of your heart come to life and take effect. Positive words uplift, Negative words put down. Words have the power to give life and words have the power to take life! I heard of the story of a young man a few months ago who took his life because of the power of words. Words spoken by someone else to him advising him to take his life and he listened.
