One of the main themes of ACIM is the idea of forgiveness. The Course shows that forgiveness is not merely pardoning some body because of their wrongdoings, but alternatively, it's the recognition that there is nothing to forgive. It asserts that what we understand as wrongdoings are fundamentally the consequence of our own misperceptions and projections. In flexible the others, we're, in reality, flexible ourselves. ACIM emphasizes that forgiveness is really a path to internal peace and liberation from the burdens of resentment and anger.

Yet another elementary theory of A Program in Miracles may be the indisputable fact that the bodily earth is an illusion. It posits our sensory experiences are unreliable signals of reality and that correct perception can only be achieved via a shift in consciousness. The Um Curso em Milagres  distinguishes between the "real world," which is really a state of peace and oneness beyond the material world, and the "vanity earth," known by concern, separation, and conflict. Based on ACIM, our main purpose is to wake from the dream of the ego world and come back to the understanding of our divine nature.

ACIM also presents the idea of the Sacred Nature as a guide and instructor within the individual. This spiritual presence is observed as the source of motivation and knowledge, supporting us produce possibilities that lead people nearer to truth and away from illusion. The Program shows that through our readiness to listen to the Sacred Spirit's advice, we can accessibility a deeper understanding of our purpose and the road to healing.
