Peace is where everybody gets along with each other. Peace is freely speaking your mind, with or without words. A free living, a loving world. Peace is a good thing and if you have God's peace not only are you safe from harm, but you know God is helping you out. Peace on Earth and good will to men and everybody.
Peace is the absence of all aggressiveness.
True peace sadly is unattainable. Because no matter how good most people are, there will always be people upset over something. Having no troubles, not having to worry about anything. People in the world getting along. Not being sad, being happy, joyful.
