God 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.

Prayer 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.

In order to cooperate in the material worlds as agents of a divine power, the spirits temporarily have a material body. By the work required in their corporeal lives, the spirits improve their intelligence and, by observing God's law, they acquire the merits which will lead them to eternal happiness.

The 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.

Unshakable faith is only that which can face reason in all human epochs.
