Many people who go to church have a withered hand, i.e., they do only half the work they should; they work with one hand only, they are working on only half their possible power.  They are people self-handicapped. There are others who see with one eye only, and others who fly on one wing. It is that sort of thing which accounts largely for the church’s in effectiveness. Only fullness of life in sacrificial service will convince a critical world.
