During the 1800's, Uriah Smith engaged himself in the monumental task of deciphering the prophecies of Daniel and the Revelation.Guided by the Holy Spirit, historical events unfolded to his mind in the prophetic context of the word as he studied deeply into the writings and accounts of reliable historians. Step by step, a foundational platform of truth was established and solid principles of prophetic interpretation were plainly set forth. Ellen G. White was shown that this book in particular was written under inspiration and would prove instrumental in spreading the light of the third angel's message to the world. She emphasised the necessity of strictly adhering to the interpretations of these prophecies as laid out by Uriah Smith in this book.
