Peace is a person - it’s not a by product of a state of mind or just and emotion - it is a spirit.  It’s and entity that embodies heaven and caries its atmosphere on earth.  You can not loose peace if you understand that peace is a spirit. You don’t just get to keep the peace; you get to keep Peace Himself.  Eph 2:14 says, “He Himself is our peace.”  You can force people to receive peace - you have to carry it and wet their appetite for it.
