A Program in Wonders, usually abbreviated as ACIM, is a profound and powerful religious text that emerged in the latter 50% of the 20th century. Comprising over 1,200 pages, this extensive work is not just a book but an entire program in spiritual change and internal healing. A Program in Wonders is unique in its approach to spirituality, pulling from various spiritual and metaphysical traditions presenting a method of thought that seeks to cause people to a situation of internal peace, forgiveness, and awareness with their true nature.

The roots of A Program in Miracles could be tracked back again to the collaboration between two individuals, Helen Schucman and Bill Thetford, both of whom were outstanding psychologists and researchers. The course's inception acim audio occurred in the first 1960s when Schucman, who was a scientific and research psychologist at Columbia University's University of Physicians and Surgeons, started to see a series of internal dictations. She identified these dictations as coming from an internal style that identified it self as Jesus Christ. Schucman initially resisted these activities, but with Thetford's support, she began transcribing the communications she received.

Around a period of eight years, Schucman transcribed what can become A Program in Wonders, amounting to three quantities: the Text, the Workbook for Pupils, and the Manual for Teachers. The Text lays out the theoretical base of the class, elaborating on the key ideas and principles. The Book for Students includes 365 lessons, one for each time of the entire year, developed to steer the audience by way of a day-to-day practice of applying the course's teachings. The Guide for Educators provides further guidance on how best to understand and teach the maxims of A Course in Miracles to others.

Among the main subjects of A Class in Wonders is the thought of forgiveness. The class shows that true forgiveness is the key to internal peace and awareness to one's heavenly nature. Based on its teachings, forgiveness is not simply a moral or ethical exercise but a fundamental change in perception. It requires allowing get of judgments, grievances, and the belief of sin, and instead, viewing the planet and oneself through the contact of enjoy and acceptance. A Program in Wonders highlights that true forgiveness leads to the recognition that individuals are interconnected and that separation from each other can be an illusion.
