The student of Christian Science early notes the importance attached to demonstration; in fact, he finds that it is paramount in his progress and success. He therefore earnestly seeks the spiritual meaning of the word and its correct employment in daily experience.
To demonstrate is to prove, to establish, to produce evidence or the scientific solution of a problem. Hence neither blind belief nor mere guesswork can be a factor in spiritual demonstration, nor, indeed, is the human outlining of desirable results or attainments, the method of proving the truths of Christian Science. Thoughtful study of the textbook of Christian Science, "Science and Health with Key to the Scriptures," and the other writings of Mary Baker Eddy will give the student an understanding of the infinite, unchanging divine Principle, God, and show him that obedience to this divine Principle, in so far as he apprehends it, is the means of bringing into conscious realization, not human desire, ambition, or will, but the divine law and plan for man already established in Mind.
Mrs. Eddy says (Science and Health, pp. 502, 503): "There is but one creator and one creation. This creation consists of the unfolding of spiritual ideas and their identities, which are embraced in the infinite Mind and forever reflected. These ideas range from the infinitesimal to infinity, and the highest ideas are the sons and daughters of God." Here we find clear reasoning from divine cause to divine effect. "The unfolding of spiritual ideas" becomes apparent to human consciousness through spiritual understanding in the manner required for meeting the human need, but these ideas remain spiritual, perfect, eternal, forever "embraced in the infinite Mind." One does not use spiritual understanding to demonstrate matter. Cause and effect are alike. The utilization of Love's infinitude does not produce materiality, but the actual manifestation of Love.
