I have said that we should never get a Christian society unless most of us became Christian individuals. That does not mean, of course, that we can put off doing anything about society until some imaginary date in the far future. It means that we must begin both jobs at once—(1) the job of seeing how ‘Do as you would be done by’ can be applied in detail to modern society, and (2) the job of becoming the sort of people who really would apply it if we saw how.
