How does the author use foreshadowing in Hinds' Feet on High Places?

In Chapter Eight, just when it seems things are hopeless and lonely, Much-Afraid is able to draw upon her newly-discovered internal strength and find great joy in the path the Shepherd has laid out for her. Even though the Shepherd reiterates that there will indeed be yet another detour on the journey, Much-Afraid continues on faithfully, demonstrating the growing closeness between herself and the Shepherd. This foreshadows the fact that the negative voices in her head are being replaced by the Shepherd's loving direction.
