James 3:2-5 (NKJV)
The words we use are far more important than most people have realized. Some people have gotten the wrong idea about the value of our words, in part because of some extreme, unbiblical teaching in this area. However, a study of what the Bible teaches about words will show the significance of the words we use in our everyday life. The words we speak every day will set the course for our life. The direction our life is headed today is based on the words we have spoken in the past.
In James 3:2-5 we have a couple of good examples of how our words work. First, James gives the example of a bit in the horses' mouth, that little thing can direct a huge animal and guide it to where it needs to go. Next, James talks about the rudder on a ship and how the pilot can set the direction the ship will go with a just very small part of the ship. Then James says that in the same way the tongue is small but it can do big things. If we want to set our course in life, if we want to turn some things around in our life, it is going to happen through our words.
So what should we be saying, what should we talk about? What we need to do is find out what the Bible has to say and talk about that. It is not as though our words have some magic power to them, but when our words are in agreement with God's Word we are allowing God an open door to move in our life. If our words are contrary to God's Word we restrict His operation in our life. Our words will set the course for our life; make sure you choose your words wisely and say the things that God has to say in His Word about every area of your life.
