The Urantia Book is 2,097 pages long and consists of an introductory foreword followed by 196 "papers" divided into four parts:
Part I, titled "The Central and Superuniverse", addresses what the authors consider the highest levels of creation, including the eternal and infinite "Universal Father", his Trinity associates, and the "Isle of Paradise".
Part II, "The Local Universe", describes the origin, administration, and personalities of the local universe of "Nebadon", the part of the cosmos where Earth resides. It presents narratives on the inhabitants of local universes and their work as it is coordinated with a scheme of spiritual ascension and progression of different orders of beings, including humans, angels, and others.
Part III, "The History of Urantia", compiles a broad history of the Earth, presenting a purported explanation of the origin, evolution, and destiny of the world and its inhabitants. Topics include Adam and Eve, Melchizedek, essays on the concept of the Thought Adjuster, "Religion in Human Experience", and "Personality Survival".
Part IV, "The Life and Teachings of Jesus", is the largest part at 775 pages, and is often noted as the most accessible and most impressive, narrating a detailed biography of Jesus that includes his childhood, teenage years, family life, and public ministry, as well as the events that led to his crucifixion, death, and resurrection. It continues with papers about appearances after he rose, Pentecost, and, finally, "The Faith of Jesus".
