Quote from A Course in Miracles Text Chapter 12 - THE HOLY SPIRIT'S CURRICULUM.

T-12.IV.7. The Atonement is not the price of your wholeness, but it is the price of your awareness of your wholeness. 2 For what you chose to "sell" had to be kept for you, since you could not "buy" it back. 3 Yet you must invest in it, not with money but with spirit. 4 For spirit is will, and will is the "price" of the Kingdom. 5 Your inheritance awaits only the recognition that you have been redeemed. 6 The Holy Spirit guides you into life eternal, but you must relinquish your investment in death, or you will not see life though it is all around you.
