This was written around 1904 by Ellen G. White of what she was shown of what would happen in the future. Who was she? What else did she write? You can read and search her writtings for free at whiteestate.org or listen to them in audio format at ellenwhiteaudio.org. She wrote many books and letters that have been as informative today as they were when they were written. Great Controversy in the final chapters you will find what she wrote about the times we are living in today and God's promise to be with his people to the very end. One of my personal favorites is Desire Of Ages about the life of Christ. The more you read her writtings and compare it with the KJV Bible the more you will understand the Bible.
