Theology is normally thought of in qualitative terms. Self's Destiny and Self is the first book to address theology in quantitative terms, wherein the mathematical relationships found within the Holy Bible are evaluated. The result is new information and new principles that challenge the current understanding of all existing religions. Using Quantitative Theology, this textbook demonstrates mathematically that the Holy Bible is the inspired and revealed word of God by showing that the Book of Revelation, written prior to 100 AD, contains data only obtainable using mathematical and computational processes that were not available until the 1960s. The book also discusses worldviews and it quantifies and analyzes how your nature determines your goals, how you relate to other people, how you relate to God, and your view of life, death and the world in general. This is accomplished by developing a model for a person that contains a submodel of the True Universe, which represents self's nature (soul). It is one's nature that determines every decision an individual makes and establishes each person's truth, anxiety, hope and emotional stability. Three primary model types are identified in this book: 1) Occult-Centered Models 2) Self-Centered Models 3) Biblically-Centered Models. All people in the world possess a unique model or nature that determines who you are and consists of one, or a blend of two, of the three primary model types. The relationship between the three primary models, the seven churches described in the Book of Revelation, and the seven-branch Menorah is analyzed with respect to the world's population using a normal distribution. The analysis shows the percentage of people with a specific nature matches the number of people judged at a given time during the Tribulation period as stated in the Book of Revelation. It also identifies the amount of time each person will spend in tribulation as a function of the seven basic natures. The text takes the understanding of the Trinity to a new depth by introducing the Father, Son and Holy Spirit in terms of multiple sets of dimensions in space. A new Original Sin calendar is introduced, which starts at 0000 OS with the fall of man in the Garden of Eden and continues through God's reconciliation with mankind. The synchronization between the calendar of Original Sin and the Gregorian calendar is evaluated. The text concludes by discussing how you can influence your ultimate destiny today and ensure that your nature will be judged acceptable by God to enter the New Age to come.
