(Proverbs 29:22 KJV) An angry man stirreth up strife, and a furious man aboundeth in transgression.
Anger and fury are not the problem here. They are emotions that come and go. The problem is people who allow themselves to be controlled by these reactions. It is the man who is known for his temper or the woman who is treated like delicate china because of her short fuse.
Allowing your emotions to control you leads to sin. When they determine the behavior and response they are “transgression” (6588). The unsaved can control their responses. Even more, children of God can do so, and must.
So? Temperance of behavior is not an option. When you lose it, repentance is not an option. Walk in righteousness. Sometimes that means self control, sometimes confession.
