“… The acceptance of the Atonement by everyone is only a matter of time. This may appear to contradict free will because of the inevitability of the final decision, but this is not so. You can temporize and you are capable of enormous procrastination, but you cannot depart entirely from your creator, who set the limits on your ability to miscreate. An imprisoned will engenders a situation which, in the extreme, becomes altogether intolerable. Tolerance for pain may be high, but it is not without limit. Eventually everyone begins to recognize, however dimly, that there must be a better way…

… Spiritual vision literally cannot see error, and merely looks for Atonement. All solutions the physical eye seeks dissolve. Spiritual vision looks within and recognizes immediately that the altar has been defiled and needs to be repaired and protected. Perfectly aware of the right defense it passes over all others, looking past error to truth. Because of the strength of its vision, it brings the mind into its service. This re-establishes the power of the mind and makes it increasingly unable to tolerate delay, realizing that it only adds unnecessary pain. As a result, the mind becomes increasingly sensitive to what it would once have regarded as very minor intrusions of discomfort…

… Only the mind can create because spirit has already been created, and the body is a learning device for the mind. Learning devices are not lessons in themselves. Their purpose is merely to facilitate learning. The worst a faulty use of a learning device can do is to fail to facilitate learning. It has no power in itself to introduce actual learning errors. The body, if properly understood, shares the invulnerability of the Atonement to two-edged application. This is not because the body is a miracle, but because it is not inherently open to misinterpretation…”
