John gives us a clear and distinct thesis in John 20:30-31. We can summarize John’s thesis in one word: believe. He says, “I’ve written this book, including these particular signs, so that you might believe.” In the course of twenty-one chapters, John will answer three questions: (1) What do we need to believe? (2) What does it mean to believe? (3) Why do we need to believe? There are seven signs in John’s account of the gospel (what he calls the things that “are written”) to help us answer these questions.
