Our goals should stretch us bit by bit. So often when we think we have encountered a ceiling, it is really a psychological or experimental barrier that we have built ourselves. We built it and we can remove it. Just as correct principles, when applied, carry their own witness that they are true, so do correct personal improvement programs. But we must not expect personal improvement without pain or some 'remodeling.' We can't expect to have the thrills of revealed religion without the theology. We cannot expect to have the soul stretching without Christian service.
