A Course in Miracles, usually abbreviated as ACIM, is a profound and influential spiritual text that emerged in the latter 50% of the 20th century. Comprising over 1,200 pages, this detailed work is not really a guide but a complete class in religious transformation and inner healing. A Program in Wonders is unique in their method of spirituality, drawing from numerous spiritual and metaphysical traditions to provide a method of thought that seeks to cause persons to a state of internal peace, forgiveness, and awareness to their correct nature.

The sources of A Class in Miracles can be traced back once again to the relationship between two people, Helen Schucman and Bill Thetford, equally of acim podcast whom were distinguished psychologists and researchers. The course's inception occurred in the first 1960s when Schucman, who was a clinical and research psychologist at Columbia University's College of Physicians and Surgeons, started to have a series of internal dictations. She identified these dictations as originating from an inner style that discovered it self as Jesus Christ. Schucman originally resisted these activities, but with Thetford's inspiration, she started transcribing the communications she received.

Over an amount of seven years, Schucman transcribed what might become A Program in Wonders, amounting to three amounts: the Text, the Workbook for Students, and the Handbook for Teachers. The Text lies out the theoretical basis of the program, elaborating on the core concepts and principles. The Workbook for Students includes 365 classes, one for each day of the season, made to guide the reader by way of a daily exercise of applying the course's teachings. The Guide for Teachers offers more guidance on the best way to realize and teach the maxims of A Class in Wonders to others.

One of many key subjects of A Program in Miracles is the thought of forgiveness. The course teaches that correct forgiveness is the main element to internal peace and awareness to one's heavenly nature. According to their teachings, forgiveness is not merely a moral or honest practice but a basic shift in perception. It requires letting move of judgments, grievances, and the perception of failure, and alternatively, viewing the world and oneself through the lens of love and acceptance. A Class in Wonders emphasizes that correct forgiveness results in the acceptance that people are interconnected and that divorce from one another can be an illusion.
