I was sick with anger, resentment and blame. I woke up realizing I needed a Savior - a savior to save me from my anger, from my bitterness, from my attitude. But angry words can be very destructive, very painful. They can cut like a knife. Yes, this sinful attitude can be very destructive.
All sin is destructive.
It always hurts someone else and destroys you. Maybe not immediately, like murder would, but it does destroy somebody at some point. Love your neighbor, love your enemies, love your self, love God. Love never gives up. Love cares for others more than for self.
