You can google the movie and read all about it. What I noticed the most, besides the story line, was the black community, itself. What a great support group. Their church was their stronghold. Prayer was their strength.
Abileen is a prayer intercessor. She writes down her prayers because she feels God listens better when she writes them down. People come to her and ask her to pray for them. She's the writer and God her inspiration. If it weren't for her faith, she wouldn't have been able to get through the day. If it weren't for her faith, the book wouldn't have gotten written. And no book--no movie.
