From as far back as the 16th century, when St. Edmund Campion of England spoke of a great day that would reveal all men's consciences, a coming day of enlightenment has been foretold. It is purported to be a day in which God will supernaturally illuminate the conscience of every man, woman, and child on earth. Each person, then, would momentarily see the state of their soul through Gods eyes and realize the truth of His existence. This book is the ONLY comprehensive and authoritative guide to this event, using Scripture and testimony from the Saints and Visionaries to explain this great miracle of Gods Mercy.
