63. The reign of goodness being established upon the Earth, it is necessary that spirits hardened in evil, and those who would be able to bring trouble to it, should be excluded. God has given them the necessary time for their improvement; but the moment when the globe must elevate itself into the hierarchy of worlds by the moral progress of its inhabitants, being arrived, the sojourn of spirits and incarnated beings, will be forbidden to those who have not profited by the instructions which they have been received in this world. They will be exiled into inferior worlds, as were formerly those of the adamic race upon our Earth, whilst their places will be filled by better spirits. It is this separation at which Jesus will preside, which is represented by these words of the last judgment: “The good will be on my right hand and the wicked on my left” (chap. XI, from item n° 31 on).
