Forgiveness holds a vital role in the teachings of ACIM. Unlike main-stream notions of forgiveness, which regularly include pardoning the perceived wrongdoings of the others, ACIM's forgiveness is a procedure of issuing judgments and grievances held against oneself and others. It is just a recognition that the perceived sins and errors are grounded in the illusions of the confidence, and through forgiveness, one can see beyond these illusions to the natural purity and divinity in most being. ACIM shows that forgiveness is really a way to internal peace and the key to undoing the ego's hang on the mind.

The Book for Pupils, comprising 365 lessons, is a practical information built to lead the student through a major process. Each lesson targets a certain theme, guiding the practitioner to use the teachings in their everyday lives. The lessons protect a wide variety of acim , including belief, forgiveness, love, and the nature of reality. The repeated nature of the Workbook is intentional, reinforcing the indisputable fact that regular exercise is essential for the transformation of consciousness.

A Class in Miracles also introduces the thought of the Sacred Spirit as helpful information and intermediary between the egoic brain and the real Self. The Sacred Heart is indicated as a caring and nonjudgmental inner voice that helps people reinterpret their experiences and perceptions in position with truth. ACIM encourages a continuing conversation with the Sacred Spirit, seeking advice and knowledge in all facets of life.

One of the special facets of ACIM is its utilization of Christian terminology and symbolism, which could originally cause some to classify it as a Religious text. But, the class transcends traditional spiritual limits and speaks to the common axioms of spirituality. ACIM encourages individuals from all faiths (or none) to set about a trip of self-discovery and internal transformation, emphasizing personal experience around dogma.
