What is the main theme in the novel, God’s Radar?

The theme of the novel develops gradually. There is the longing of people to return to order, simplicity, and faith in an increasingly complex and disturbing world. Roxie's parents are happy in the thought that their daughter will not be drawn to drugs or promiscuity while she attends the academy. Marian enjoys immersing herself in the many activities that fill her otherwise empty days. The author paints a sympathetic picture of the members of the Baptist congregation—they are kind, pious, and charitable, and value family and home. Dr. Caraman is friendly and concerned about everyone in spite of his national fame. And yet the novel conveys a sense of unease.
