How does the author use foreshadowing in The Diary of a Country Priest?

In Chapter Two, the priest meets his first challenges in his new parish. Disturbed by the lack of innocence in the children, as well as the shrewdness of the businessmen in the area, he feels people take advantage of him because of his naiveté. The Curé de Torcy tells him it is because he is the type of person injustice searches out. As a way of foreshadowing the remainder of the story, the Curé de Torcy warns the priest to be on his guard against the injustices of the world.
