Do we see a sinful man at times, perhaps a hateful or a sick man, or do we even seem to be such a man? By reversing the erroneous, material sense testimony, we can never find false qualities in man, for man is the expression of God. God, good, is ever present, and evil is never where God is; hence it is ever absent. Error occupies no space, for all space is filled with good, with God.
To reverse our way of thinking, we must let divine Mind rule our thoughts, knowing that God is the only Mind of man, the only Mind there is. We must subordinate material sense and cultivate spiritual sense, which alone can tell us the truth regarding anything and everything.
Mary Baker Eddy writes in "Science and Health with Key to the Scriptures" (p. 120), "Science reverses the false testimony of the physical senses, and by this reversal mortals arrive at the fundamental facts of being." Since the testimony of the material senses is false to begin with, it should not be difficult, with persistent practice, for the student of Christian Science to know the very opposite of this falsity—to know what is true.
