A Course in Miracles states:
"Adam's "sin" could have touched none of you, had you not believed that it was the FATHER Who drove him out of Paradise. For it is in that belief that knowledge of the Father was lost, for it is only those who do not understand Him that COULD believe it."
"When you willed to leave Him, He gave you a voice to speak FOR Him, because He could no longer share His knowledge with you without hindrance. Direct communication was broken, because you had made another voice through another will. The Holy Spirit calls you both to remember and forget."
"He tells you to return your whole mind to God, BECAUSE IT HAS NEVER LEFT HIM. If it has never left Him, you need only perceive it as it is to BE returned."
"God did not leave His Children comfortless, even though they left Him. The voice they put in their minds was NOT the voice of His Will, for which the Holy Spirit speaks."
