Peace has to do with peace with others, peace with God and peace with ourselves. It describes the nature of salvation that God offers us in Christ. Peace denotes the gift of wholeness that God gives to us when we come to him in faith. It is not simply the absence of conflict but a calm strength in the midst of conflict. It is like coming home and being at peace, returning to a place of security, safety, and joy.
Peace is the result of grace.
I was approached once in the Philippines by a young man who wanted to sell me a method of finding inner peace. He came to my office and wanted me to hear a recording that he thought could be used in the church, perhaps in small groups. So we listened together. The tape directed us to lie on the floor while a deeply resonant sonorous voice gave instructions. The voice said, Tell your toes to go to sleep, be quiet, rest.
