28. It is also by the good it does that Spiritism proves its divine mission. It cures physical evils, but, above all, moral maladies, which are the most important works by which it affirms itself. Its most sincere adepts are not only those who have been astonished by the sight of its extraordinary phenomena, but those who have been touched to the heart by the consolation it gives; those who have been delivered from the tortures of doubt; those whose courage has been sustained by it in affliction, who have drawn strength from the certitude of the future which it has brought to them, with a knowledge of their spiritual being and destiny; those whose faith is unchangeable because they feel it and comprehend.
Those who see in Spiritism only material effects cannot comprehend its moral power; as incredulous, who know it only by its phenomena of which they do not admit its first cause (God), see in Spiritists only jugglers and charlatans. It is then, not by the performance of wonderful works that Spiritism will triumph over incredulity; it is by multiplying its moral benefits. For, if they will not believe in the mighty works it accomplishes, they experience, like all the world, sufferings and afflictions, and no one refuses alleviation and consolation.
