The book is dedicated to the mysteries and miracles of the Old and New Testaments. Indeed, from the point of view of common sense, it is very difficult to understand how, for example, within six days God created the Universe, the Earth, the flora and fauna, and, most importantly, man. The Egyptian plagues, the parting of the sea during the flight of the Jews from Egypt, the miracles of Moses in the desert, and the fall of the walls of Jericho seem mysterious. The New Testament holds no less secrets. To this day, not only the birth of Jesus, but also the youthful years of His life, His appearance, and His Resurrection remain a hidden mystery for Bible readers. The author tried to present various, including scientific, interpretations of biblical miracles and riddles.
