The revolution of Jesus is in the firstplace and continuously a revolution of the human heart or spirit. It did not and does not proceed by means of the formation of social institutions and laws, the outer forms of our existence, intending that these would then impose a good order of life upon people who come under their power. Rather, his is a revolution of character, which proceeds by changing people from the inside through personal relationship to God in Christ and to one another. It is one that changes their ideas, beliefs, feelings, and habits of choice, as well as their bodily tendencies and social relations. It penetrates to the deepest layers of their soul.
