6. But the most numerous evils are those which men create by their own vices, - those which spring from their pride, from their selfishness, from their ambition, from their cupidity, from their excess in all things. Hence the cause of wars, calamities, dissensions, injustice, oppression of the feeble by the strong, and of the greater part of diseases.
God has established laws full of wisdom, which are only for the good of men. All that is necessary to man’s welfare is his obedience to them. His way is traced out for him by his conscience. The divine law is engraved upon his heart. Moreover, God reminds him incessantly by his messiahs and prophets, by all incarnates who have received the mission of enlightening him, of moralizing him, of improving his condition, and in these latter days by the multitude of discarnates who manifest on all sides, - if man conformed himself rigorously to the divine laws, he would evade, without doubt, the severest evils, and would live happily upon the Earth. If he doesn’t obey them, it is by virtue of his free will; and he must submit himself to the consequences. (“The Gospel According to Spiritism,” Chap. 5, items 4, 5, and 6)
