The book begins by introducing John as the author and has letters to seven churches of that day. Some think that these churches also represent periods of history. Various visions follow which are highly symbolic which allows many different interpretations. They have been understood by various groups to represent past and future events. Some believe that many of these prophecies have already been fulfilled. Others think they will be fulfilled at the end of time. Others think they affirm the victory of Christ over all enemies, but do not refer to specific events. The book ends with a vision of the faithful souls in the next life rejoicing around the throne of God.
