When it says “…whose existence cannot be materially demonstrated.”…I presume that means to mortals living still upon their material worlds of origin? I mean, mota and our morontial education and journey to Paradise and fusion with our Adjuster should provide a material or factual demonstration of objective reality, right?
Here’s a repeat of the quote in full:
103:9.9 (1141.7) The full realization of the reality of mortal life consists in a progressive willingness to believe these assumptions of reason, wisdom, and faith. Such a life is one motivated by truth and dominated by love; and these are the ideals of objective cosmic reality whose existence cannot be materially demonstrated.
Not exactly. What I think they’re saying is that truth and love are the most objectively real ideals in the whole cosmos but they are a subjective experience for the personality. Objective reality is love and truth but not the relationship one has with love and truth. Love and truth are personal qualities belonging to personalities, and relationships between persons are primarily subjective.
I can swear that I love my kids and they can rightfully say, “Really, then prove it.” And we all know that it can’t be proven objectively, only subjectively, yet the fact that it exists is undeniable to me. Love, like truth, is an inconcussible reality. I’m so sure of it, I’ll give my life for it. The same goes with God, who is Love. My kids could also ask me to prove I love God, but they wouldn’t dare, because they know it’s true and it’s also ridiculous to ask for such a thing. They may have said when they were young that the fact that they didn’t get their way with something is proof that I didn’t love them, but maturity generally cures that problem. Love and truth, the most objective ideals in the universe, simply cannot be proven objectively. The proof is the actual relationship itself.
(1139.2) 103:7.10 In the mortal state, nothing can be absolutely proved; both science and religion are predicated on assumptions. On the morontia level, the postulates of both science and religion are capable of partial proof by mota logic. On the spiritual level of maximum status, the need for finite proof gradually vanishes before the actual experience of and with reality; but even then there is much beyond the finite that remains unproved.
