A farmer is helpless to grow grain; all he can do is provide the right conditions for the growing of grain. He cultivates the ground, he plants the seed, he waters the plants, and then the natural forces of the earth take over and up comes the grain…This is the way it is with the Spiritual Disciplines – they are a way of sowing to the Spirit… By themselves the Spiritual Disciplines can do nothing; they can only get us to the place where something can be done.
