"If we ask how this most remarkable of the miracles of history was performed, we are amazed at the simplicity of God's method. The world needed a saving faith, and the formula was that such a faith comes by a particular kind of fellowship. Jesus was deeply concerned for the continuation of his redemptive work after the close of his earthly existence, and his chosen method was the formation of a redemptive society. He did not form an army, establish a headquarters, or even write a book. All he did was to collect a few unpromising men and women, inspire them with the sense of his vocation and theirs, and build their lives into an intensive fellowship of affection, worship, and work."
