From ACIM"A miracle is a correction. It does not create, nor really change at all. It merely looks on devastation, and reminds the mind that what it sees is false. It undoes error, but does not attempt to go beyond perception, nor exceed the function of forgiveness. Thus, it stays within time's limits. Yet it paves the way for the return of timelessness and love's awakening, for fear must slip away under the gentle remedy it brings.
A miracle contains the gift of grace, for it is given and received as one. And thus, it illustrates the law of truth the world does not obey, because it fails entirely to understand its ways. A miracle inverts perception which was upside down before, and thus it ends the strange distortions that were manifest. Now is perception open to the truth. Now is forgiveness seen as justified?
Forgiveness is the home of miracles. The eyes of Christ deliver them to all they look upon in mercy and in love. Perception stands corrected in His sight, and what was meant to curse has come to bless.
