ACIM Quote from Chapter 1, Section 3 - Revelation, Time and Miracles.

Revelation induces complete but temporary suspension of doubt and fear. It reflects the original form of communication between God and his creations, involving the extremely personal sense of creation sometimes sought in physical relationships. Physical closeness cannot achieve it. Miracles, however, are genuinely interpersonal, and result in true closeness to others. Revelation unites you directly with God. Miracles unite you directly with your brother. Neither emanates from consciousness, but both are experienced there. Consciousness is the state that induces action, though it does not inspire it. You are free to believe what you choose, and what you do attests to what you believe.
