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 KardecThe incarnation was not initially imposed on the spirits as a punishment. It is rather necessary for the spirits' improvement and for the fulfillment of God's works. Everyone has to submit to it, no matter if one takes the evil or the good path. Only those who take the good path will improve quickly, they do not delay to arrive at the end in less painful conditions.
Allan KardecPrayer is always acceptable to God when dictated by the heart, for the intention is everything in his sight; and the prayer of the heart is preferable to one read from a book, however beautiful it may be, if read with the lips rather than with the thought.
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.
