“When these worlds of unhappiness gradually came into existence and the separation from God took place for a great number of beings, as I said before, Divine Law provided for the possibility to regain the happy state of existence these beings once were in. But certain decisions and changes had to be made, always according to the free will of the fallen spirits, either individually or as a group. This was also foreseen by God and provided for and left open at the time to effect at the proper time. All this is part of the plan of salvation for which God enlisted the help of all spirits who remained faithful to Him, as well as those who reached and are still reaching sufficient development after their fall, to help along.” (PL #20)
