In a courtroom, the valuable witness is the one who is sure of his facts, presents them convincingly, and permits no amount of coercion or crafty manipulation to trap him into testifying falsely. Christian Science calls on us to be true witnesses to our divine nature as God's children. It asks us to prove, in practical ways, that man is the perfect, spiritual reflection or idea of divine Mind and to refuse to believe the false testimony of the carnal mind, which it exposes as nonexistent.
Our Master said of his own purpose, "To this end was I born, and for this cause came I into the world, that I should bear witness unto the truth." The truth is that Spirit is omnipotent good, and matter impotent error. When divine Mind is seen as the only reality, mortal mind will not obscure the truth. It will have no power to confuse or intimidate. The glorious knowledge that the law of Love reigns inviolate and supreme will guide, sustain, and support all our endeavors. Mary Baker Eddy, the Discoverer and Founder of Christian Science, writes in "Miscellaneous Writings" (p. 218), "False realistic views sap the Science of Principle and idea; they make Deity unreal and inconceivable, either as mind or matter; but Truth comes to the rescue of reason and immortality, and unfolds the real nature of God and the universe to the spiritual sense, which beareth witness of things spiritual, and not material."
In scientific thinking, the substantiality of spiritual evidence is its accuracy and genuineness; material evidence is quickly disqualified. A mother, greatly discouraged over her son's school report, confided to a student of Christian Science that the boy's teachers regarded him as a "problem child." The mother herself seemed to concur in that belief, listing the boy's faults and shortcomings in great detail. The Scientist interrupted her discourse by telling her she must not let mortal mind bear false witness in her own thinking. It was further explained that God's child cannot be identified with stupidity, inferiority, or deficiency, because he is a complete and perfect expression of divine intelligence.
