Anger is just one letter short of spelling danger. Anger causes broken relationships, lack of peace, physical problems, and can even lead to murder. It is nothing to play with.
Anger is an acid that can do more harm to the vessel in which it is stored than to anything on which it is poured. ~ Mark Twain
Ephesians 4:26 “In your anger do not sin”: Do not let the sun go down while you are still angry.
