Among the key themes of ACIM is the concept of forgiveness. The Course shows that forgiveness is not just pardoning someone for their wrongdoings, but instead, it's the acceptance that there surely is nothing to forgive. It asserts that what we understand as wrongdoings are ultimately caused by our personal misperceptions and projections. In forgiving others, we're, in fact, forgiving ourselves. ACIM highlights that forgiveness is really a road to inner peace and liberation from the burdens of resentment and anger.

Another elementary principle of A Program in Miracles is the indisputable fact that the bodily earth can be an illusion. It posits our physical experiences are unreliable signs of fact and that correct perception can only just be performed by way of a shift in consciousness. The Program distinguishes between the "real-world," which is a state of peace and oneness beyond the material a course in miracles , and the "pride earth," indicated by concern, separation, and conflict. In accordance with ACIM, our primary function would be to wake from the desire of the confidence world and return to the recognition of our divine nature.

ACIM also presents the thought of the Sacred Spirit as helpful tips and teacher within the individual. This religious presence is seen as the source of inspiration and knowledge, supporting people make choices that cause people nearer to truth and away from illusion. The Program teaches that through our readiness to hear the Holy Spirit's advice, we are able to entry a further knowledge of our purpose and the way to healing.
