Faith is in fact a power operating all through our lives, and imparted to us from the time of our birth. This power is obscured as soon as reason is developed, which occurs during the process of acquiring the knowledge needed for merely maintaining life; and then one loses one's self-confidence as well as one's confidence in others. This is doubt, which is the greatest enemy of the soul in its progress towards self-realization. It is removed as soon as one perceives that faith is really a power from God, by which He seeks to express Himself through the individual.
