He who sees most clearly and enlightens other minds [10] most readily, keeps his own lamp trimmed and burning. He will take the textbook of Christian Science into his class, repeat the questions in the chapter on Recapitula- tion, and his students will answer them from the same source. Throughout his entire explanations, the teacher [15] should strictly adhere to the questions and answers con- tained in that chapter of “Science and Health with Key to the Scriptures.” It is important to point out the lesson to the class, and to require the students thor- oughly to study it before the recitations; for this spirit- [20] ualizes their thoughts. When closing his class, the teacher should require each member to own a copy of the above-named book and to continue the study of this textbook. The opinions of men cannot be substituted for God’s [25] revelation. It must not be forgotten that in times past, arrogant ignorance and pride, in attempting to steady the ark of Truth, have dimmed the power and glory of the Scriptures, to which this Christian Science textbook is the Key. [30] That teacher does most for his students who most divests himself of pride and self, spiritualizes his own [Page 93.] thought, and by reason thereof is able to empty his stu- [1] dents’ minds, that they may be filled with Truth. Beloved students, _so_ teach that posterity shall call you blessed, and the heart of history shall be made glad! [5] _Can fear or sin bring back old beliefs of disease that have_ _been healed by Christian Science?_ The Scriptures plainly declare the allness and oneness of God to be the premises of Truth, and that God is good: in Him dwelleth no evil. Christian Science au- [10] thorizes the logical conclusion drawn from the Scriptures, that there is in reality none besides the eternal, infinite God, good. Evil is temporal: it is the illusion of time and mortality. This being true, sin has no power; and fear, its coeval, [15] is without divine authority. Science sanctions only what is supported by the unerring Principle of being. Sin can do nothing: all cause and effect are in God. Fear is a belief of sensation in matter: this belief is neither main- tained by Science nor supported by facts, and exists only [20] as fable. Your answer is, that neither fear nor sin can bring on disease or bring back disease, since there is in reality no disease. Bear in mind, however, that human consciousness does not test sin and the fact of its nothingness, by believing [25] that sin is pardoned without repentance and reforma- tion. Sin punishes itself, because it cannot go unpun- ished either here or hereafter. Nothing is more fatal than to indulge a sinning sense or consciousness for even one moment. Knowing this, obey Christ’s Sermon on the [30] Mount, even if you suffer for it in the first instance,— [Page 94.] are misjudged and maligned; in the second, you will [1] reign with him.
