A Program in Wonders, usually abbreviated as ACIM, is a profound and influential spiritual text that surfaced in the latter half the 20th century. Comprising around 1,200 pages, that comprehensive work is not really a guide but an entire program in spiritual transformation and internal healing. A Program in Miracles is unique in its method of spirituality, drawing from numerous religious and metaphysical traditions to present a system of believed that seeks to cause people to circumstances of internal peace, forgiveness, and awakening for their correct nature.

The roots of A Program in Miracles could be tracked back to the relationship between two individuals, Helen Schucman and Bill Thetford, both of whom were outstanding psychologists and researchers. The course's inception occurred in the early 1960s when a course in miracles Schucman, who was simply a scientific and study psychologist at Columbia University's University of Physicians and Surgeons, started to have a series of internal dictations. She described these dictations as via an internal voice that identified itself as Jesus Christ. Schucman initially resisted these experiences, but with Thetford's encouragement, she began transcribing the messages she received.

Around a period of seven decades, Schucman transcribed what might become A Course in Wonders, amounting to three sizes: the Text, the Workbook for Pupils, and the Manual for Teachers. The Text sits out the theoretical base of the course, elaborating on the core methods and principles. The Book for Students contains 365 instructions, one for every single time of the entire year, made to steer the audience via a daily practice of applying the course's teachings. The Information for Educators provides further advice on how to realize and train the axioms of A Program in Miracles to others.

Among the central themes of A Class in Miracles is the notion of forgiveness. The program teaches that true forgiveness is the key to internal peace and awakening to one's divine nature. According to their teachings, forgiveness is not simply a moral or ethical practice but a essential change in perception. It involves allowing move of judgments, grievances, and the belief of failure, and instead, seeing the world and oneself through the lens of love and acceptance. A Program in Miracles highlights that correct forgiveness contributes to the acceptance that individuals are interconnected and that separation from each other can be an illusion.
