Consider ships: They are so large that strong winds are needed to drive them. But pilots direct their ships wherever they want with a little rudder. 5 In the same way, even though the tongue is a small part of the body, it boasts wildly. Think about this: A small flame can set a whole forest on fire. 6 The tongue is a small flame of fire, a world of evil at work in us. It contaminates our entire lives. Because of it, the circle of life is set on fire. The tongue itself is set on fire by the flames of hell.
7 People can tame and already have tamed every kind of animal, bird, reptile, and fish. 8 No one can tame the tongue, though. It is a restless evil, full of deadly poison. 9 With it we both bless the Lord and Father and curse human beings made in God’s likeness. 10 Blessing and cursing come from the same mouth. My brothers and sisters, it just shouldn’t be this way! 11 Both fresh water and salt water don’t come from the same spring, do they? 12 My brothers and sisters, can a fig tree produce olives? Can a grapevine produce figs? Of course not, and fresh water doesn’t flow from a saltwater spring either. (Common English Bible)
