The heart and violence

Many people talk about violence in the culture. They fear that the culture is a murder. When bad things happen to someone then there are protests and anger. I believe that everything begins in the human heart.
When I say the human heart, I  am explaining the motives of the person.
We have a sinful desire and there will be problems. If you have an issue in the culture then the society have a heart issue.
The only person can cure the sickness is Jesus. The human soul that reject Jesus, that soul will have anger. Jesus will bring peace to the human heart. When a person repents from their sins, then the anger will cease in the person's life.
The new heart that Jesus gives is great. The person will enjoy a great life. I am not saying that life will be perfect but the person will have wisdom. If a person face a difficult person or a difficult issue, the person will have a peace.
If a person don't have Jesus then the sinful nature will reign in the person's life. If a person wrongs someone that rejects Jesus, then the person will have violence in the heart. The person will not have forgiveness in the heart so they will use violence words and actions.
If someone wrongs this person, this person will destroy cars and hate people. That is the problem in all societies. This person needs to submit their life to Jesus. If they want to have a good life.
I need to add another point. There is personal responsibility in everyone life. This life is not perfect but a person can do the evil or good. There are consequence of being stupid. People need a new heart.

Proverbs 13:2

 From the fruit of their lips people enjoy good things,
    but the unfaithful have an appetite for violence.
