Paul says,"None of us liveth to himself." Human life involves constant association with others. A little careful thought shows clearly how interdependent we all are. It sometimes happens that it is necessary to send a message to someone many hundreds of miles away. In one such instance communication was established in less than a minute, although the distance involved covered a large country. This possibility was the outcome of careful co-operation. The carelessness or neglect of one person might have prevented a successful result.
In modern industrial plants the aim is to reduce friction and wasted effort to a minimum, and bring out the maximum of efficiency and production. When discovered, the frictional and useless are quickly eliminated. It should not be otherwise in daily living, in which we are all actively engaged. We can well ask ourselves: What is it that will make my life more joyous, my efforts more successful, my endeavors more fruitful, and my harmony more abiding? Christian Science provides a ready answer, and one that can be proved in practical demonstration. It clears the stones from life's highway, and makes our journey a gladsome one. It declares and "demonstrates that peace, joy, efficiency, success, and happiness are determined by right thinking. The Scriptures declare of a man, "As he thinketh in his heart, so is he."Humanly speaking, we are what we think, what we entertain mentally. It is, then, self-evident that our thinking is the most important factor in our experience. Right thinking eventuates in harmony; wrong thinking brings about inharmony. Spiritual ideas entertained and adhered to bring harmony, while wrong beliefs result in discord. We know that this is true in every field of human endeavor.
In the Christian Science textbook, "Science and Health with Key to the Scriptures,"Mary Baker Eddy gives this wholesome admonition (p.392): "Stand porter at the door of thought. Admitting only such conclusions as you wish realized in bodily results, you will control yourself harmoniously."How careful we are to bring into our human dwellings that which is useful, helpful, harmonious, and good! How earnestly we strive to make them comfortable, well-furnished, and beautiful! How zealous we should be in seeing to it that our mental homes are furnished with holy, healthy, right, and loving thoughts which reflect God! How quickly we should reject anything and everything that would in any way defile or mar the sacred precincts of our mental home, our holy habitation! How promptly we should welcome in every thought that would add to its peace, its purity, its loveliness! One virtue that should receive our mental hospitality is that of tolerance. It is a close companion to peace, and is allied to joy.
