'Trains, Jesus, and Murder' - a new book about Johnny Cash and his religiosity

Richard Beck is a psychology professor who teaches a weekly Bible study, and he recently published a book 'Trains, Jesus, and Murder: The Gospel According to Johnny Cash', which got his title via Beck's son who jokes that Cash's songs are all about murder, trains, and Jesus. Beck deals with questions about solidarity and patriotism, with the complexities of Cash’s simultaneously conservative and countercultural appeal, his relationship with the authorities (well, mostly, avoidance). The Quietus says the book is a "welcome companion for anyone wanting to know more about what Cash insisted was not only the key to his music but to the kingdom, too", and that it goes well with the audio of Johnny Cash reading the whole of the New Testament.
