13. 6. If there were not one God the universe could not have been created or maintained. We can infer the oneness of God from the creation of the universe, because the universe is a work connected together as one thing from beginning to end, all dependent on one God as the body depends on its soul. The universe was designed to allow God to be omnipresent, keep every detail of it under his supervision, and maintain it perpetually as one entity, that is, preserve it. This is why Jehovah God says he is "the First and the Last, the Beginning and the End, the Alpha and the Omega" (see Isaiah 44:6; Revelation 1:8, 17); and why he says elsewhere that he makes all things, stretches out the heavens, and extends the earth by himself (see Isaiah 44:24).

This vast system called the universe is a work connected as one thing from beginning to end because God had a single purpose in creating it: an angelic heaven populated by the human race. All the things that make up the world are means of fulfilling that purpose, because someone who intends an end result also intends the means to achieve it.

[2] If we view this world as a work containing the means of fulfilling the aforementioned purpose, we can see the created universe as a work connected together into one thing; and see that this world is a complex structure of useful functions arranged and prioritized for the sake of the human race, the source of the angelic heaven.

Divine love cannot intend anything other than that people should forever have the blessings of its divineness. Divine wisdom cannot produce anything other than useful things that are means of fulfilling that purpose.

Upon examining the world with this universal idea in mind, every wise person is capable of grasping that there is one Creator of the universe and that his essence is love and wisdom. For this reason every single thing in this world is of benefit to us; if it seems of no direct benefit, at least it is of indirect benefit. The fruits of the earth and the animals benefit us with food and also with clothing.

[3] Among the marvels of this world is that the lowly insects called silkworms clothe with silk and magnificently adorn both women and men from queens and kings down to maids and butlers. And the lowly insects called bees supply wax for the lamps that give churches and royal courts their splendor.

Some people examine certain aspects of the world in isolation rather than looking at everything as a chain from purposes through intermediate means to results. Therefore those people cannot see that the universe is the handiwork of one God. The same is true for people who do not see creation as the product of divine love acting through divine wisdom. Neither group is able to see that God dwells in individual useful things because he dwells in the purpose behind them. Yet everyone who has some purpose is also involved in the means of achieving it, because deep within every one of the means lies the purpose as the force that drives and guides it.

[4] Some do not view the universe as the handiwork of God and the home of his love and wisdom, but view it instead as a product of nature and as the home of the sun's heat and light. They close the higher levels of their mind toward God and open the lower levels of their mind toward the Devil. In the process, they take off their humanity and put on the nature of a wild animal. It is not just a belief of theirs that humans are like animals; they themselves actually become like animals. They become as crafty as foxes, as fierce as wolves, as deceptive as leopards, as savage as tigers; or they take on the nature of crocodiles, snakes, horned owls, or night birds. In the spiritual world they even look like these wild animals from a distance. Their love for evil takes these shapes.

166. 2. These three, the Father, the Son, and the Holy Spirit, are three essential components of one God. They are one the way our soul, our body, and the things we do are one. In any given thing there are general essential components and there are also specific essential components. The general and specific components combine to make one essence.

In our case, our general essential components are our soul, our body, and the things we do. These three components combine to make one essence, as you can see from the fact that one component comes from and exists for the other in an unbroken chain. We begin from our soul. The soul is the essence of the semen that originates us. Our soul not only initiates but also sequentially produces the features of our body. Then there are the things we do, which come from both our soul and our body. Because one of these components produces another, and therefore the subsequent components are grafted onto and connected to those that came before them, it follows that these three components share one essence. This is why they are called the three essential components.
