Key words in A Course in Miracles - Forgiveness

   A Course in Miracles  sees forgiveness as the act of looking beyond illusions to the truth of our inherent  innocence as a child of God.

The major difficulty that you find in genuine forgiveness on your part is that you still believe you must forgive the truth, and not illusions. You conceive of pardon as a vain attempt to look past what is there; to overlook the truth, in an unfounded effort to deceive yourself by making an illusion true. ... .Because you think your sins are real, you look on pardon as deception. For it is impossible to think of sin as true and not believe forgiveness is a lie.                           W-134.4:1-3.5:1. 

 Miracle-minded forgiveness is only correction. It has no element of judgment at all. The statement "Father forgive them for they know not what they do" in no way evaluates what they do. It is an appeal to God to heal their minds. There is no reference to the outcome of the error. That does not matter.                 T-2.V.A.16(6). 

Nothing in boundless love could need forgiveness. And what is charity within the world gives way to simple justice past the gate that opens into Heaven. No one forgives unless he has believed in sin, and still believes that he has much to be forgiven. Forgiveness thus becomes the means by which he learns he has done nothing to forgive. Forgiveness always rests upon the one who offers it, until he sees himself as needing it no more.                  T-26.IV.1:3-7.

...there must be condemnation before forgiveness is necessary. ... although God does not forgive, His Love is nevertheless the basis of forgiveness. Fear condemns and love forgives. Forgiveness thus undoes what fear has produced, returning the mind to the awareness of God. For this reason, forgiveness can truly be called salvation. It is the means by which illusions disappear.                              W-46.1:2/2:1-5.
