The series starred actors Joe Mantegna and Mary Steenburgen as Joan's parents Will and Helen, Jason Ritter as her paraplegic older brother Kevin, and Michael Welch as her younger brother Luke. The family relationships and plot situations were written more realistically than other shows with spiritual themes. Various storylines that spanned multiple episodes dealt with the consequences of Kevin's accident, Will's job as a police officer, Helen's career as an art teacher, and Luke's aspirations to be a scientist. God quotes Bob Dylan, Emily Dickinson and the Beatles rather than any scripture or verses. Furthermore, God is portrayed with a very human personality. In "Touch Move", he tells Joan that he has to send her "down there", and laughs when she becomes worried he means Hell, when he meant the school basement. Also, in one episode, he hands Joan a book from a store they have just left. When Joan accuses him of stealing, he remarks "Well, technically everything's mine".
