Convoluted or Philosophical?

Passage from the text:
" For altogether as Thou art, Thou only knowest, Who art unchangeably, and knowest unchangeably, and willest unchangeably. And Thy Essence Knoweth and Willeth unchangeably; and Thy Knowledge Is, and Willeth unchangeably; and Thy Will Is, and Knoweth unchangeably. Nor doth it appear just to Thee, that as the Unchangeable Light knoweth Itself, so should It be known by that which is enlightened and changeable. Therefore unto Thee is my soul as "land where no water is," because as it cannot of itself enlighten itself, so it cannot of itself satisfy itself. For so is the fountain of life with Thee, like as in Thy light we shall see light."
- Book XIII Chapter XVI

Commentary:
By the end of the book, the reader is clued in to the fact that Augustine understands a great deal about God. What does he understand about God? That only God can know His unknowable self. While this sounds like some mental gymnastics, Augustine believes it to be true- in a way that is as complicated as it is obscure. What reasons does Augustine have for sharing this with his audience? For none other than the evangelization of souls wandering aimlessly through life, looking for meaning, as Augustine once did.
