The sources of A Program in Wonders could be tracked back again to the venture between two people, Helen Schucman and William Thetford, both of whom were prominent psychologists and researchers. The course's inception occurred in the early 1960s when Schucman, who was simply a clinical and study psychiatrist at Columbia University's School of Physicians and Surgeons, started to see some internal dictations. She described these dictations as coming from an interior style that determined it self as Jesus Christ. Schucman originally resisted these experiences, but with Thetford's inspiration, she began transcribing the messages she received.

Over a period of seven decades, Schucman transcribed what would become A Course in Miracles, amounting to three amounts: the Text, the Workbook for acim Students, and the Guide for Teachers. The Text sits out the theoretical base of the program, elaborating on the primary concepts and principles. The Workbook for Students contains 365 instructions, one for every single time of the season, made to guide the reader via a daily practice of applying the course's teachings. The Handbook for Educators provides more guidance on how to realize and teach the maxims of A Course in Wonders to others.

Among the key styles of A Program in Miracles is the thought of forgiveness. The course shows that true forgiveness is the main element to inner peace and awareness to one's heavenly nature. According to their teachings, forgiveness isn't only a moral or honest practice but a simple change in perception. It involves letting go of judgments, issues, and the belief of crime, and as an alternative, seeing the planet and oneself through the lens of enjoy and acceptance. A Course in Wonders stresses that true forgiveness contributes to the recognition that people are all interconnected and that divorce from one another is an illusion.

Yet another significant facet of A Class in Miracles is its metaphysical foundation. The class presents a dualistic view of reality, distinguishing between the ego, which represents divorce, fear, and illusions, and the Holy Spirit, which symbolizes enjoy, reality, and religious guidance. It suggests that the confidence is the origin of suffering and conflict, as the Holy Heart provides a pathway to healing and awakening. The target of the class is to help persons surpass the ego's confined perception and arrange with the Holy Spirit's guidance.
