From the book description:
This is no ordinary book. It is a set of probing questions (1,450 in fact) designed to help individuals or groups, especially groups, to dive deeply into Saint John’s Gospel. No answers are provided, but the questions are phrased in such a way as to set a person in a reliable direction for finding the answers.
The questions correspond to the verses of the Gospel and require active and personal interaction. Some of the questions are easy, some difficult, and they are marked accordingly. Some questions include background information or hints that help the reader along. Some were written with a fair bit of humor. Any person or group using these questions to explore John will find themselves entertained as well as informed and inspired.
