Heavenly Father needs a calm channel. The key to calmness is to disengage from negative give and take as soon as we begin to feel irritated. Recognize that this is the beginning of an escalating power struggle and withdraw for a few minutes until you can deal with the situation calmly. Parents who carefully listen to their children's ideas without criticism and without interruption, who take their suggestions, who speak in calm tones, who discipline calmly, logically, and consistently are respecting their children. Such parents have established the foundation to require similar behavior from their children.
Actions are far more important than words.
Children need not lectures but role models. I asked him if I had ever said that to him, and he said no. I explained in a very serious and firm tone that since I never say that to him, he is never to say it to me. That was the first and last time. Model the behavior you expect your children to exhibit.
