For every kind of beast and bird, of reptile and creature of the sea, is tamed and has been tamed by mankind. But no man can tame the tongue. It is an unruly evil, full of deadly poison. (James 3:7, 8 NKJV) What a hopeless cause, to tame the tongue. I was teaching through this passage years ago and realized that all of my ideas for taming the tongue wouldn't work. There was nothing I could do about it?
The answer lies in the source. James asks: "Does a spring send forth fresh water and bitter from the same opening? or " Can a fig tree bear olives, or a grapevine bear figs? "Thus no spring yields both saltwater and fresh." The source determines the end. Jesus said: "For out of the abundance of the heart the mouth speaks." (Matthew 12:32 NKJV) The tongue does not control itself, it is under the influence of the heart. Therefore, whatever our heart is full of is what our tongue will say.
How many times have words caused damage? Some careless comment that bruised a tender soul? I have found the answer to this problem. Only God can tame the tongue and only if we are willing to let Him fill our hearts with His abundance. If my heart is full of doubt and fear, that will be my speech. If full of faith and praise, that will roll off my tongue. If I want sweet water to flow, then sweetness has to come in and fill my heart.
