"Love holds no grievances.
You who were created by love like itself can hold no grievances and know your Self. ²To hold a grievance is to forget who you are. ³To hold a grievance is to see yourself as a body. ⁴To hold a grievance is to let the ego rule your mind and to condemn the body to death. ⁵Perhaps you do not yet fully realize just what holding grievances does to your mind. ⁶It seems to split you off from your Source and make you unlike Him. ⁷It makes you believe that He is like what you think you have become, for no one can conceive of his Creator as unlike himself." (ACIM, W-68.1:1-7)

"It is as sure that those who hold grievances will redefine God in their own image, as it is certain that God created them like Himself, and defined them as part of Him. It is as sure that those who hold grievances will suffer guilt, as it is certain that those who forgive will find peace. It is as sure that those who hold grievances will forget who they are, as it is certain that those who forgive will remember.

Would you not be willing to relinquish your grievances if you believed all this were so? Perhaps you do not think you can let your grievances go. That, however, is simply a matter of motivation. Today we will try to find out how you would feel without them."

(ACIM, W-68.3:1–4:4)

"My grievances hide the light of the world in me. I cannot see what I have hidden. Yet I want to let it be revealed to me, for my salvation and the salvation of the world." (ACIM, W-69.9:4-6)

"We have shouted our grievances so loudly that we have not listened to His Voice. We have used our grievances to close our eyes and stop our ears." (ACIM, W-72.10:11-12)

"Let me realize today that the problem is always some form of grievance that I would cherish. Let me also understand that the solution is always a miracle with which I let the grievance be replaced. Today I would remember the simplicity of salvation by reinforcing the lesson that there is one problem and one solution. The problem is a grievance; the solution is a miracle. And I invite the solution to come to me through my forgiveness of the grievance, and my welcome of the miracle that takes its place." (ACIM, W-90.1:2-6)
