"With the tongue we praise our Lord and Father, and with it we curse men, who have been made in God's likeness." James 3:9
Positive words seem less volatile than negative words but their power can be amazing. A good word can confirm talent or skills of someone that needs encouragement. A good word can also change the course of someone's day, week, month or lifetime. The tongue was formed primarily to bless. It was given to bless God and others and by doing this it will bless ourselves. Use your mouth to bless at all times. You'll find the current of your life to flow in a corresponding direction. When blessing comes out of your heart, God makes sure that blessing comes into it.
