[Testimonies for the Church 2:522-525, (1870).]
In the creation of man, the Lord designed that he should be active and useful. Yet many live in this world as useless machines, as though they hardly existed. They brighten the path of none, they are a blessing to none. They live only to burden others. So far as their influence on the side of right is concerned, they are mere ciphers; but they tell with weight upon the wrong side. Search the lives of such closely, and scarcely an act of disinterested benevolence can be found. When they die, their memory dies with them. Their names soon perish; for they cannot live, even in the affections of their friends, by means of true goodness and virtuous acts. With such persons, life has been a mistake. They have not been faithful stewards. They have forgotten that their Creator has claims upon them, and that He designs them to be active in doing good and in blessing others with their influence. Selfish interests attract the mind and lead to forgetfulness of God and of the purpose of their Creator. CH 95.1
All who profess to be followers of Jesus should feel that a duty rests upon them to preserve their bodies in the best condition of health, that their minds may be clear to comprehend heavenly things. The mind needs to be controlled; for it has a most powerful influence upon the health. The imagination often misleads, and when indulged, brings severe forms of disease upon the afflicted. Many die of diseases which are mostly imaginary.... CH 95.2
Some are so afraid of air that they will muffle up their heads and bodies until they look like mummies. They sit in the house, generally inactive, fearing they shall weary themselves and get sick if they exercise either indoors or out in the open air. They could take habitual exercise in the open air every pleasant day, if they only thought so. Continued inactivity is one of the greatest causes of debility of body and feebleness of mind. Many are sick who ought to be in very good health and thus in possession of one of the richest blessings they could enjoy. CH 95.3
I have been shown that many who are apparently feeble, and are ever complaining, are not so badly off as they imagine themselves to be. Some of these have a powerful will, which, exercised in the right direction, would be a potent means of controlling the imagination and thus resisting disease. But it is too frequently the case that the will is exercised in a wrong direction, and stubbornly refuses to yield to reason. That will has settled the matter; invalids they are, and the attention due to invalids they will have irrespective of the judgment of others. CH 96.1
I have been shown mothers who are governed by a diseased imagination, the influence of which is felt upon husband and children. The windows must be kept closed because the mother feels the air. If she is at all chilly, and a change is made in her clothing, she thinks her children must be treated in the same manner, and thus the entire family are robbed of physical stamina. All are affected by one mind, physically and mentally injured through the diseased imagination of one woman who considers herself a criterion for the whole family. The body is clothed in accordance with the caprices of a diseased imagination, and smothered under an amount of wrappings which debilitate the system. The skin cannot perform its office; the studied habit of shunning the air and avoiding exercise, closes the pores, the little mouths through which the body breathes,—making it impossible to throw off impurities through that channel. The burden of labor is thrown upon the liver, lungs, kidneys, etc., and these internal organs are compelled to do the work of the skin. CH 96.2
Thus persons bring disease upon themselves by their wrong habits; yet, in the face of light and knowledge, they will adhere to their own course. They reason thus: “Have we not tried the matter? and do we not understand it by experience?” But the experience of a person whose imagination is at fault should not have much weight with anyone. CH 97.1
The season most to be dreaded by any going among these invalids is winter. It is winter indeed, not only outdoors, but in, to those who are compelled to live in the same house and sleep in the same room. These victims of a diseased imagination shut themselves indoors and close the windows; for the air affects their lungs and their heads. Imagination is active; they expect to take cold, and they will have it. No amount of reasoning can make them believe that they do not understand the philosophy of the whole matter. Have they not proved it? they will argue. It is true that they have proved one side of the question,—by persisting in their own course,—and yet they do take cold if in the least exposed. Tender as babies, they cannot endure anything; yet they live on, and continue to close the windows and doors, and hover over the stove, and enjoy their misery. They have surely proved that their course has not made them well, but has increased their difficulties. Why will not such allow reason to influence the judgment and control the imagination? Why not now try an opposite course, and in a judicious manner obtain exercise and air out of doors? CH 97.2
