“A religion, even popular Christianity, could enjoy a boom altogether divorced from the transforming power of the Holy Spirit and so leave the church of the next generation worse off than it would have been if the boom had never occurred. I believe that the imperative need of the day is not simply revival, but a radical reformation that will go to the root of our moral and spiritual maladies and deal with causes rather than with consequences, with the disease rather than with symptoms.”
