This introduction provides context for the book by explaining that the author will be taken in visions to heaven and hell to witness things firsthand in order to provide detailed accounts. It references biblical examples of prophets like Ezekiel, John, and Paul being taken up spiritually by God to experience visions of the spiritual realm. The author has accepted God's commission through the Holy Spirit to record what she sees in heaven and hell for the purpose of this book. She does not claim the same level of authority or revelation as biblical prophets but believes God has a purpose for revealing more details about the afterlife at this time in history as the end times approach.
