A Program in Wonders, usually abbreviated as ACIM, is a profound and influential religious text that emerged in the latter 50% of the 20th century. Comprising over 1,200 pages, this comprehensive perform is not only a book but a complete program in religious change and inner healing. A Class in Miracles is unique in their method of spirituality, drawing from different religious and metaphysical traditions to provide something of thought that seeks to cause persons to a state of inner peace, forgiveness, and awareness to their correct nature.

The sources of A Program in Wonders may be traced back again to the cooperation between two individuals, Helen Schucman and Bill Thetford, both of whom were distinguished psychologists and acim internships researchers. The course's inception happened in the first 1960s when Schucman, who was simply a medical and research psychiatrist at Columbia University's School of Physicians and Surgeons, began to see a series of inner dictations. She described these dictations as via an inner voice that identified itself as Jesus Christ. Schucman initially resisted these activities, but with Thetford's encouragement, she began transcribing the communications she received.

Over a period of eight decades, Schucman transcribed what can become A Program in Wonders, amounting to three sizes: the Text, the Book for Students, and the Handbook for Teachers. The Text lays out the theoretical basis of the course, elaborating on the primary methods and principles. The Workbook for Pupils includes 365 instructions, one for every single time of the entire year, developed to guide the audience via a daily training of applying the course's teachings. The Guide for Teachers provides further advice on how best to understand and teach the axioms of A Class in Miracles to others.

Among the central themes of A Course in Wonders is the notion of forgiveness. The course teaches that true forgiveness is the key to internal peace and awareness to one's heavenly nature. In accordance with its teachings, forgiveness is not only a ethical or moral exercise but a simple change in perception. It requires making go of judgments, grievances, and the perception of failure, and instead, seeing the entire world and oneself through the lens of enjoy and acceptance. A Class in Wonders stresses that true forgiveness results in the recognition that people are all interconnected and that divorce from one another can be an illusion.
