"There are many kinds of spiritual experience. Some are like the conversions of the great religious leaders of the past; others seem purely psychological. Some are sudden or instantaneous; others are a gradual learning experience. But all of them, whatever form they take, have one effect: They make a person capable of doing something he could not do before.
"As Bill puts it, 'When a man or a woman has a spiritual awakening, the most important meaning of it is that he has now become able to do, feel, and believe that which he could not do before on his unaided strength and resources alone.'"
