“But one was needed to end the separation, and in this one are all the rest joined. For what alone in all creation could be affected by your free will but your own self? But one was needed to, of his own free will, join his will with his Father’s for it to be done for all. This is all correction or atonement means, and all that is in need of your acceptance. Join your brother who made this choice for all and you are reunited with the Christ in you.” (ACOL, C:12.14)
Jesus frequently speaks of “one” when he is getting us to understand that we need only join with our brother—one brother—to effect salvation for all. He makes a similar statement in the Manual of A Course in Miracles, that one individual only was needed to bring atonement to all the world. And many of us see that one as Jesus himself, 2000 years ago. But Jesus does not take anything unto himself that cannot be exemplified in each of us, in this day and time. Elsewhere he says that there is nothing that he has that all of us cannot have, only that he has nothing else, that what he has is potential in us.
We use our free will, a our real will that is one with God’s, to join with our brothers and sisters. We make the decision to forgive and to join. And we are never the same after this. Anything that the other can do is not sufficient to rue our choice to join with him or her. We always forgive, knowing that nothing bad has actually happened, that we are lost in illusion and so bad things don’t affect us, with this understanding.
So we, each of us, find our way home by loving our brother, by walking hand in hand with our brother in holy relationship.
