This book is for those Christians who want to understand the mysteries surrounding the events of the end time contained in Chapter 24 of Matthew and Chapters 6 through 17 of the book of Revelation. Also, deep mysteries contained in the books of Isaiah and Jeremiah will be unsealed and explained. To give you a feel for these mysteries, some examples are listed below. What does Jesus mean when He says in Matthew 24:29: immediately after the tribulation of those days the sun shall be darkened, and the moon shall not give her light? What is Jesus referring to when He says: "the stars shall fall from heaven, and the powers of the heavens shall be shaken"? What does it mean in Revelation 6:12 when it says: "the sky is rolled back like a scroll"? What is being described in Revelation 12:7-9 and when does it happen when we read: Michael and his angels going forth to war with the dragon; and the dragon warred and his angels? What is being described in Isaiah 24:19 when it says: "for the windows on high are opened, and the foundations of the earth tremble"? Also, when and why is it happening? Three independent case studies showing the rapture of the church occurring at the mid-point of the tribulation are presented. They are detailed and accurate in their use of scripture and strictly adhere to the teaching of both the Apostle Paul and the Apostle John. If you want to understand these mysteries plus many more, this is the book for you. When you are finished reading this book, much of Matthew Chapter 24 and the book of Revelation will become unsealed to you.
