How does the author use foreshadowing in Confessions?

In Book VI, Augustine begins to understand that when the Scriptures say that God made man in his own image, this does not mean that God has a body. It is a metaphor referring to the Godlike attributes of man being also a creative and reasoning creature. This is an example of why it is so important to study the spirit and intent of the Scriptures, not the literal meaning of a phrase. This foreshadows Augustine's theological theory that the prophet Moses wrote the Scriptures so that the simple-minded could have something to believe in, but the more intellectual would be able to seek a deeper meaning in the word of God. It also foreshadows the positive influence of the spiritual and metaphorical works of the Platonists on Augustine.
