The tongue is a small thing, but what enormous damage it can do. A tiny spark can set a great forest on fire. And the tongue is a flame of fire. It is full of wickedness that can ruin your whole life. It can turn the entire course of your life into a blazing flame of destruction, for it is set on fire by hell itself.
Blessing and cursing come pouring out of the same mouth. Surely, my brothers and sisters, this is not right! If you are wise and understand God’s ways, live a life of steady goodness so that only good deeds will pour forth.
James 3:5,6,10,13 (NLT)
