The question even has an emotional element to it when we ask if God plus Beethoven (or all human art) is more than God alone.
While it may seem intellectually quite obvious that God plus something else (like the whole universe) must give us something greater than God, the concept of infinity turns this simple mathematical conclusion on its head.
There is no ratio between what is finite and what is infinite. You can’t add to infinity! God is Infinite. So there is no ratio between God and the created world, no ratio between human genius and Divine Wisdom. Beethoven’s musical genius adds nothing to God’s unlimited celestial harmonies.
The answer to this unique question also has to do with the imagined worldview of the human ego. According to Swedenborg, because of our self-centeredness, we do not perceive reality correctly and live mostly in fantasy and imaginary dreams. In spite of our learned sense of self, we have no existence outside of our relationships (and friendships). And our relationship with God is most important to our existence.
In fact, scientist/theologian Emanuel Swedenborg stated that if God were not sustaining the universe at every single moment, it would immediately turn to foam and froth and totally disappear—including us.
We are real because God is real.
God is the ultimate reality. Period. Every created thing in the universe (inorganic and organic) is simply a receptive form of some level of God’s influence. The created world was fashioned by God putting measureable limits on divine activity (much the way mathematical calculus coordinates and subordinates infinities into various concepts of constraints and limits). Creation is less than God.
God is even above heaven (angels are also finite creatures).
The human race was created so that God could share eternal happiness with others. This is how Divine Love finds its fullness in time. So while we finite human creatures are nothing compared to the Creator, our lives are important to God’s realizing and becoming the Alpha and Omega.
We properly accept God’s love by offering it back to God. We are really alive and vivified according to the intensity and degree of life we receive and give back in reciprocal union and partnership with the God of heaven and earth. In other words, God’s wisdom finds real ways to unite His Infinity with our finite nature (calculus proves such a relationship is theoretically possible when we consider that an infinite number of points occupy any finite and curved line or length).
This sacred partnership (and divine ratio) is how we humans can live forever through an eternal God.
