How would the story be different if it were told from dee’s point of view? why did the author choose to have mama narrate the story?

If it were told from Dee's point of view, you would be able to see more about their world. You would get to see would it would be like to live in their shoes.

I know this only answers one of the questions, but I hope it helps a little bit!!

in paragraph 6 of "sinners in the hands of an angry god" by jonathan edwards, he talks about how doing good things alone will not save men from going to hell because they're at the mercy of the will of god. "spiritual reform" provides men with a false sense of safety.
