“Before a holy relationship there is no sin. The form of error is no longer seen, and reason, joined with love, looks quietly on all confusion, observing merely, ‘This was a mistake.’ And then the same Atonement you accepted in your relationship corrects the error, and lays a part of Heaven in its place. How blessed are you who let this gift be given!” (T-22.VI.5)
We can easily accept Atonement when we accept it through our special relationships turned holy. A holy relationship, we are told, is a means of saving time. And when we turn to our brother, overlooking his mistakes as just mistakes (not sins), then we see Heaven itself in our relationship. We have walked further toward the grace that is always held out to us.
We have been confused when we fail to overlook mistakes in our brother. Of course, overlooking is hard when we believe ourselves to have really been attacked, and to have suffered from this attack. But to think in such a way is to compound the error, the mistake.
Our brother had only attacked us because his mind is lost in illusion, and we ourselves are attached to that illusion as well. Our real Self has not been harmed in any way. We are intact. And being intact, we can show our brother an innocent face, a face that has not been hurt, and in the showing of this unhurt face, our brother will receive (as do we) a part of Heaven itself.
