There are two kinds of people in regards to anger. One person gets angry and outwardly explodes. The other person gets angry and inwardly stews. Of the two, the latter is the most dangerous. The person who quickly explodes tends to get the anger out of their system. The other harbors suppressed anger. That suppressed anger can build up for years and years, either making the person sick, or exploding in a much more dangerous way later on in life. Many people who fret deny being angry. Because they don't explode with anger, they are of the opinion that they aren't angry, or they feel that they have their anger under control.
 
Fretting is anger that stews inwardly. This anger starts controlling our minds and thoughts and makes us think of the hurt, offense, or injustice that was done to us. Fretting also causes us to frequently re-live these negative events and feel the pain all over again. Fretting eats away at your mind and body. It can, with time, produce a number of mental and physical diseases. No wonder God tells us, "Do not fret!" That one command from the Lord is given to us to save our lives! In fact, I have learned that most everything, if not everything, God tells us is in order to save our lives!
 
Besides being a threat to our physical well-being, fretting robs us of much mental and soul peace. You can't have peace and be one who frets. Fretting is another bad mental habit that needs to be broken in our lives! Let's obey God and fret not!
