There exist rules for training that are valid for athletic sports and are also valid for the spirit. If all of a sudden someone tells you, “Walk 30 miles”, you will say, “Impossible!” But if you begin to walk five miles each day the first week, eight miles the second week, and so on progressively, within a year you will have no difficulty in walking 30 miles. What happened? The athletic abilities were asleep, maybe even atrophied, for lack of activity. Once they were put into motion, the muscles awoke and strengthened.
