329. We can tell what a useful function is from the goal of the creation of the universe. The goal of the creation of the universe is to bring about an angelic heaven; and since an angelic heaven is the goal, so is humanity or the human race, since that is where heaven comes from. It follows, then, that everything that has been created is an intermediate goal, and that the functions are useful in the sequence, on the level, and in the specific way that they relate to humanity, and through humanity to the Lord.

154. The reason the Lord created the universe and everything in it by means of the spiritual world's sun is that this sun is the first emanation of divine love and wisdom, and as explained above (52-82), everything comes from divine love and wisdom.

There are three components of everything that has been created, no matter how large or how small it is: a purpose, a means, and a result. There is nothing created that lacks these three components. In the largest instance, the universe, these three components arise in the following pattern: the purpose of everything is in that sun that is the first emanation of divine love and wisdom; the means of everything is in the spiritual world; and the result of everything is in the physical world. I will describe below [167-172] how these three components occur in both first and last forms.

Since there is nothing created that lacks these three components, it follows that the universe and everything in it has been created by the Lord by means of the sun where the purpose of everything resides.
