"Were it not for the love of God, hearts would be inanimate, spirits would wither, and the reality of man would be bereft of the everlasting bestowals."

"Real love is the love which exists between God and His servants, the love which binds together holy souls. This is the love of the spiritual world, not the love of physical bodies and organisms. For example, consider and observe how the bestowals of God successively descend upon mankind, how the divine effulgences ever shine upon the human world. There can be no doubt that these bestowals, these bounties, these effulgences emanate from love. Unless love be the divine motive, it would be impossible for the heart of man to attain or receive them. Unless love exists, the divine blessing could not descend upon any object or thing. Unless there be love, the recipient of divine effulgence could not radiate and reflect that effulgence upon other objects. If we are of those who perceive, we realize that the bounties of God manifest themselves continuously, even as the rays of the sun unceasingly emanate from the solar center. The phenomenal world through the resplendent effulgence of the sun is radiant and bright. In the same way the realm of hearts and spirits is illumined and resuscitated through the shining rays of the Sun of Reality and the bounties of the love of God. Thereby the world of existence, the kingdom of hearts and spirits, is ever quickened into life. Were it not for the love of God, hearts would be inanimate, spirits would wither, and the reality of man would be bereft of the everlasting bestowals."
