Rowena Duplessis could be forgiven for having religious doubts.

She lost her home in New Orleans during Hurricane Katrina, only a year after the death of her husband. Last fall, her son committed suicide. Then, robbers broke into the trailer she and her son once shared, which made her afraid to stay there alone.
