The book of Revelation has been for many a book that is difficult to understand, a situation that has caused distorted knowledge about its fulfillment to spread even in religious circles.
The book of Revelation is for the purpose of discovering things that are about to happen. This principle is made manifest in the introduction of the book: "The Revelation of Jesus the Christ, which God gave him to show to his servants the things that must soon come to pass; and he declared it, sending it by his angel to John his servant, "(1:1)
Why then has it been difficult to understand it? Because of the way everyone has approached him. The Revelation of Jesus given by God, as read in the introduction of the book, is not a book of symbolic, mystical or esoteric readings, this has been the failure; The book of Revelation is a book of prophecy, and can only be understood precisely through the Spirit of Prophecy (19:10); So, each of the 22 chapters that make up the book is a Word that opens our eyes, and prepares us, to face the things that are about to happen, just in the preamble of Jesus' return to earth.
This is the purpose that leads us to develop this series of teachings.
