Claim. God did not create casually; like an artist seeking a masterpiece, He totally invested true life, true love, and the true ideal into creation — a self-emptying that became the universal pattern of love.
Elaboration. §1.3 ties purpose-of-creation to a specific operation: total investment. “The act of creation required a huge investment of energy. The wish of any artist is to create the greatest masterpiece, and he spares no pains, putting everything he has into making it… God invested everything He had as the Subject in order to create His object. Through the act of creation, He began to exist not for Himself but for His object” (1.3. God’s motive in creating the universe, 78-111, 1975.5.6). And: “You might think that when God created with the words, ‘Let there be light…’ it just seemed like child’s play to Him. Yet that was not the actual case. He totally invested true life, true love and the true ideal into them” (ibid). The unique law of love is that this investment does not diminish the investor — “the more love is in motion, instead of decreasing, it increases” (ibid, 237-127, 1992.11.13). Give-and-take in love generates more than it consumes, which is why God can absolutely give without absolute loss.
