Angry

" "Be angry, and do not sin": do not let the sun go down on your wrath, nor give place to the devil." (Ephesians 4:26-27 NKJV) #Bible

Being angry isn't the sin, it's allowing it to turn into wrath when it continues. The danger is to give the devil a place in wrath producing only evil. Anger is energy expressed in determination, or forbearance for example. It's our choice, use anger for good or evil.
