Ellen G. White 
The Great Controversy Between Christ and His Angels, and Satan and His Angels 
Spiritual Gifts Volume One

In 1858, White was moved to bear her testimony at a funeral, going into a two-hour vision in front of the congregation. Mostly concerning the 'great controversy, ’ she was widely encouraged to write it out, producing this book, which describes the whole history of sin chronologically, from before sin ever entered the universe to after its final destruction in The New Earth.
