Mortals believe that sight and hearing are personal possessions; that each mortal has these faculties embodied in his corporeality and that time, accident, or other material beliefs may impair or destroy them. Christian Science presents an opposite view. It points to the healings by Christ Jesus of those who were blind and deaf as evidence that God never impairs, but rather perpetuates the faculties of man. Matter testified in Jesus' time, "Here is a mortal who was born blind; he will never see." But a moment later he saw. The Master's understanding that man and his faculties are spiritual, God-constituted and immutable, dissipated the godless material condition, and the patient saw. The conditions of negative matter yielded to the mandate of positive Mind.
Jesus understood that man's ability to perceive can be neither bestowed nor destroyed by unintelligent matter. God, Spirit, infinite Mind, the only Ego, is man's Life, and inherent in this Ego—not in matter—are man's seeing and hearing, forever coincident with his being. God does not cause or know unseeing being. What God does not cause or know, is not and cannot be. A blind or a deaf mortal is as unconceived by and unknown to God, the all-knowing Mind, as is a sick mortal. The only true man, God's workmanship, has unimpairable sight and hearing.
The Bible refers to God's sight, and the Master indicated that this one sight is individualized in man. Said he, "If ... thine eye be single, thy whole body shall be full of light" (Matt. 6:22). The eye that is single—one not two—and that enlightens man's entire individuality is the perceiving faculty of infinite Mind, individualized in man.
