Those who do not use their limbs every day will realize a weakness when they do attempt to exercise. The veins and muscles are not in a condition to perform their work and keep all the living machinery in healthful action, each organ in the system doing its part. The limbs will strengthen with use. Moderate exercise every day will impart strength to the muscles, which without exercise become flabby and enfeebled. By active exercise in the open air every day, the liver, kidneys, and lungs also will be strengthened to perform their work. Bring to your aid the power of the will, which will resist cold and will give energy to the nervous system. In a short time you will so realize the benefit of exercise and pure air that you would not live without these blessings. Your lungs, deprived of air, will be like a hungry person deprived of food. Indeed, we can live longer without food than without air, which is the food that God has provided for the lungs. Therefore do not regard it as an enemy, but as a precious blessing from God.

If invalids allow themselves to encourage a diseased imagination, they will not only waste their own energies, but the vitality of those who have the care of them. I advise invalid sisters who have accustomed themselves to a great amount of clothing, to lay it off gradually. Some of you live merely to eat and breathe, and fail to answer the purpose for which you were created. You should have an exalted aim in life and seek to be useful and efficient in your own families and to become useful members of society. You should not require the attention of the family to be centered upon you, nor should you draw largely upon the sympathies of others. Do your part in giving love and sympathy to the unfortunate, remembering that they have woes and trials peculiar to themselves. See if you cannot, by words of sympathy and love, lighten their burdens. In blessing others, you will realize a blessing yourselves. (2T 533.2) MC VC

Those who, so far as it is possible, engage in the work of doing good to others by giving practical demonstration of their interest in them are not only relieving the ills of human life in helping them bear their burdens, but are at the same time contributing largely to their own health of soul and body. Doing good is a work that benefits both giver and receiver. If you forget self in your interest for others, you gain a victory over your infirmities. The satisfaction you will realize in doing good will aid you greatly in the recovery of the healthy tone of the imagination. The pleasure of doing good animates the mind and vibrates through the whole body. While the faces of benevolent men are lighted up with cheerfulness, and their countenances express the moral elevation of the mind, those of selfish, stingy men are dejected, cast down, and gloomy. Their moral defects are seen in their countenances. Selfishness and self-love stamp their own image upon the outward man. That person who is actuated by true disinterested benevolence is a partaker of the divine nature, having escaped the corruption that is in the world through lust; while the selfish and avaricious have cherished their selfishness until it has withered their social sympathies, and their countenances reflect the image of the fallen foe, rather than that of purity and holiness.

Invalids, I advise you to venture something. Arouse your will power, and at least make a trial of this matter. Withdraw your thoughts and affections from yourselves. Walk out by faith. Are you inclined to center your thoughts upon yourselves, fearing to exercise, and fearing that if you expose yourself to the air you will lose your life; resist these thoughts and feelings. Do not yield to your diseased imagination. If you fail in the trial, you can but die. And what if you do die? One life might better be lost than many sacrificed. The whims and notions which you cherish are not only destroying your own life, but injuring those whose lives are more valuable than yours. But the course we recommend will not deprive you of life or injure you. You will derive benefit from it. You need not be rash or reckless; commence moderately at first to have more air and exercise, and continue your reform until you become useful, a blessing to your families and to all around you. Let your judgment be convinced that exercise, sunlight, and air are the blessings which Heaven has provided to make the sick well and to keep in health those who are not sick. God does not deprive you of these free, Heaven-bestowed blessings, but you have punished yourselves by closing your doors against them. Properly used, these simple yet powerful agents will assist nature to overcome real difficulties, if such exist, and will give healthy tone to the mind and vigor to the body. (2T 534.2) MC VC
