There is nothing wrong to be angry because anger is the part of our natural being. But we should avoid to dwell on it because it could lead to resentment which is not good for anyone, we just have to control it before it control us. As the bible says, 'In your anger do not sin.' 'Do not let the sun go down while you still angry, and do not give the devil a foothold.
