The motif reaches a peak definition: sinlessness is the disappearance of the desire to attack. With attack gone, guilt loses its purpose and the Son of God is no longer seen as different from what he is. The teaching integrates mind-choice practice with metaphysical certainty: your experience of Heaven or hell turns on whether you perceive your brother’s innocence or make him an enemy. In that sense, the brother’s function is decisive—what you assign to him becomes your path. Seeing him as Christ brings joy and inner sight because it aligns perception with what God created. Sinlessness here is more than the absence of wrongdoing; it is the end of the attack impulse that kept wrongdoing meaningful.

This zenith stop gathers the trail into a single, highly practical definition: sinlessness is the end of the desire to attack. That definition is important because it ties sin and attack together. The ego wants to treat sin as an objective fact—something someone did—and then use that “fact” to justify attack. The Course reverses the order. It shows that the desire to attack comes first, and the perception of sin is the justification the mind manufactures. When the desire to attack is relinquished, the entire structure collapses. There is no need for guilt because there is no goal for guilt to serve.

The stop also brings relationship to the center. Your brother is not a side character in your spiritual life; he is the classroom in which you decide for Heaven or for hell. The role you give him—enemy or savior—becomes your experience, because minds are joined. If you see a guilty brother, you accept a guilty self. If you see Christ, you accept Christ. This is not moral pressure; it is a description of how perception works when mind is cause.

Notice the simplicity of the release: it is not achieved by fixing every behavior. It is achieved by letting the attack impulse be questioned and undone. The Holy Spirit does not ask you to pretend you never feel anger. He asks you to bring anger to Him as something you no longer want. The moment you are willing to relinquish attack, you have stepped toward sinlessness, because sin’s goal is attack. Without the goal, the meaning falls away.

Practice this as an immediate application. When you feel justified anger or cold withdrawal, ask: “Do I still want to attack?” Be honest. If the answer is yes, do not dramatize it—just bring it: “Holy Spirit, I do not want this.” Then ask to see the brother’s God-given function fulfilled: the function of leading you to peace. In that request, you open the door for inner sight. Joy is not forced; it is the natural effect of withdrawing belief from attack and letting Christ be what you see.
