804. Why hasn’t God endowed everyone with the same aptitudes?
“God has created all spirits equal, but each one of them has lived over a longer or shorter amount of time and has consequently developed more or fewer aptitudes. The difference lies in the degree of experience and volition – their free will – by which some advance more rapidly, endowing them a wide range of aptitudes. A medley of aptitudes is necessary so that all may contribute to the designs of Providence within the limits of the development of their physical and intellectual powers. What one cannot do, another does, and so all end up having their useful function. Furthermore, since all worlds are united in solidarity, it is necessary for the inhabitants of more highly evolved worlds – most of which were created well before yours – to come and live here in order to set an example for you.” (See no. 361)
805. In passing from a more evolved world to a lesser one, does the spirit keep all its acquired faculties intact?
“Yes, we have already told you that the spirit who has progressed cannot regress. In its spirit state, it may choose a coarser envelope or a more precarious position than the previous one, but always to serve it as a lesson and to help it progress.” (See no. 180)
Thus, the diversity of aptitudes among individuals is not related to the inmost nature of their creation, but to the degree of perfection they have reached as spirits. God has not, therefore, created an inequality of faculties, but has permitted the different degrees of development to remain in contact with one another so that the more advanced may help the more backward to progress, and also so that in needing one another, all persons may understand the law of charity that should unite them.
