How foreshadowing use in salvation Hughes?

In "Salvation" by Langston Hughes, foreshadowing is used subtly to hint at the disappointment and disillusionment that Langston will face. For example, when Langston's aunt tells him that he will see "the light of Jesus" and Langston overhears another boy lying about his experience, these moments foreshadow the internal conflict Langston will experience when he is unable to have the same spiritual revelation. Ultimately, this foreshadowing builds tension and anticipation leading to the climax of the story where Langston feels lost and betrayed.
