Join not your brother’s dreams but join with him, and where you join His Son the Father is. Who seeks for substitutes when he perceives he has lost nothing? Who would want to have the “benefits” of sickness when he has received the simple happiness of health? What God has given cannot be a loss, and what is not of Him has no effects. What, then, would you perceive within the gap? The seeds of sickness come from the belief that there is joy in separation, and its giving up would be a sacrifice. But miracles are the result when you do not insist on seeing in the gap what is not there. Your willingness to let illusions go is all the Healer of God’s Son requires. He will place the miracle of healing where the seeds of sickness were. And there will be no loss, but only gain.
