God did not create the evil. He established the laws which are always good because he is good. The spirits would have been completely happy had they faithfully observed the law since the beginning. But, being free to make choices, the spirits have not properly obeyed them so that evil come as a consequence of this unwillingness. One can then say that good corresponds to everything which is in accordance with God's law while evil is everything which opposes it.
Allan KardecIn a word, what characterizes the spiritist revelation is that while divine in its origin and of the initiative of the Spirits, its elaboration is fruit of manโs work.
Allan KardecThe more clearly a principle is understood by the intellect, the more inexcusable is the neglect to put it into practice.
Allan KardecGod leaves to our conscience the choice of the road we decide to follow, and the liberty of yielding to one or another of the opposing influences that act upon us.
