Ralph L. Ringer accepted the Messiah and call to ministry behind the steering wheel of a truck. He graduated from what is now Southern Adventist University with a BA in theology and a minor in history. He has been in full-time ministry for 50 years, focusing on teaching the book of Revelation. He found out that you cannot understand Revelation unless you understand it is the conclusion and summary of all Scripture, that God’s everlasting covenant is the same from Genesis through Revelation, and that the Messiah has always been the same (Malachi 3:6; Hebrews 13:8). After 56 years of study, he was compelled to write this book.
