A recent advertisement I saw for Science and Health said this: "People have found moral and spiritual strength by reading this book. They have also had healings of mental and physical diseases, financial burdens, and unhappy relationships." I can verify those statements through healings in my own life.
I found Christian Science when involved in an unhappy relationship. My fiancé and I had grown up together, and plans to marry after college promised to fulfill my desire to be a wife and mother. When he told me that his future no longer included me, I felt utterly rejected. I had relatives who were Christian Scientists, and I had thought that some day I would like to investigate their religion; it seemed to strengthen them in challenging times. And I turned to Christian Science in hope of finding an answer to the "why" of my situation.
In the Preface of Science and Health I found these words: "The time for thinkers has come" (p. vii). This made a deep impression on me. I asked for the help of a Christian Science practitioner, who directed me to a statement from Miscellaneous Writings: "Immortal Mind is God, immortal good; in whom the Scripture saith 'we live, and move, and have our being.' This Mind, then, is not subject to growth, change, or diminution, but is the divine intelligence, or Principle, of all real being; holding man forever in the rhythmic round of unfolding bliss, as a living witness to and perpetual idea of inexhaustible good" (pp. 82-83).
