These comprehensive selections from Ellen White's early published writings contain the sum and substance of early Adventism, along with an explanation of the historical background of the text. Such subjects as early Spiritualism, the Atonement, the significance of the 2,300 days, the "shaking time," the meaning of the Third Angel's Message, and many more essential topics were presented to shape and guide the early Advent believers, and contain a major message for today's church, as well.

The autobiographical section of the book describes the author’s conversion experience, the Millerite movement of 1840 – 1844, and the early visions that formed the foundation of her theology and ministry. A second section contains counsel on various matters pertaining to the experience of the early Adventist believers.

The final half of the book traces salvation history from the fall of Satan in heaven to the final end of sin and sinners. This materials forms the core of the later five-volume, Conflict of the Ages Series.
