A Christian society is not going to arrive until most of us really want it: and we are not going to want it until we become fully Christian. I may repeat ‘Do as you would he done by’ till I am black in the face, but I cannot really carry it out till I love my neighbour as myself: and I cannot learn to love my neighbour as myself till I learn to love God: and I cannot learn to love God except by learning to obey Him. And so, as I warned you, we are driven on to something more inward—driven on from social matters to religious matters. For the longest way round is the shortest way home.
