The reader will be appraised of how God has been speaking to His people through public and private revelation for over 2000 years. A special chapter in this work deals with some saints and holy people who have had private revelations about or visits from souls in purgatory, hell or heaven. Another chapter and several of the appendixes are devoted to Marian Apparitions to include those that are approved, not approved and those appending a decision by the Church. By far one of the greatest strengths of this undertaking is the identification of some 43 categories of concomitant extraordinary phenomena and some of the saints and holy people who have experienced them. Color paintings by artists are depicted of some saints experiencing such mystical phenomena. Another unique feature of the book is a listing of some 600 individuals from the 13th to the 21st centuries who bore the stigmata. By knowing that God is present and alive to His people this book may help bring others to a deeper faith in God.
