The first principle that pertains to the intelligence God has bestowed upon us is to know how to preserve the present organization with which we are endowed. It is man's first duty to his existence, a knowledge of which would cause him to use all prudent efforts for the preservation of his life on the earth until his work here is completed. 8:281.

Prepare to die, is not the exhortation in this Church and Kingdom; but prepare to live is the word with us, and improve all we can in the life hereafter, wherein we may enjoy a more exalted condition of intelligence, wisdom, light, knowledge, power, glory, and exaltation. Then let us seek to extend the present life to the uttermost, by observing every law of health, and by properly balancing labor, study, rest, and recreation, and thus prepare for a better life. Let us teach these principles to our children, that, in the morning of their days, they may be taught to lay the foundation of health and strength and constitution and power of life in their bodies. 11:132.

This is the duty of the human family, instead of wasting their lives and the lives of their fellow-beings, and the precious time God has given us to improve our minds and bodies by observing the laws of life, so that the longevity of the human family may begin to return. By and by, according to the Scriptures, the days of a man shall be like the days of a tree. But in those days people will not eat and drink as they do now; if they do their days will not be like a tree, unless it be a very short-lived tree. This is our business. 14:89.

We are trying to become natural in our habits, and are striving to fulfil the end and design of our creation. 13:233.

The fathers and mothers have laid the foundation for many of these diseases, from generation to generation, until the people are reduced to their present condition. True, some live to from fifty to ninety years of age, but it is an unusual circumstance to see a man an hundred years old, or a woman ninety. The people have laid the foundation of short life through their diet, their rest, their labor, and their doing this, that, and the other in a wrong manner, with improper motives, and at improper times. 2:269.

You, mothers and daughters in Israel, who are taking this course, how do you expect to live to accomplish the work the Lord has assigned you? You get up in the morning and have your cup of tea, your fried ham, your cold beef and mince pies, and everything you can possibly cram into the stomach, until you surfeit the system and lay the foundation for disease and early death. Says the mother—"Do eat, my little daughter, you are sick; take a piece of pie, toast, or meat, or drink a little tea or coffee; you must take something or other." Mothers in Israel, such a course engenders disease, and you are laying a foundation that will cut off one-half or two-thirds of the lives of your children. 12:37.

Eating for Health—Instead of doing two days' work in one day, wisdom would dictate to our sisters, and to every other person, that if they desire long life and good health, they must, after sufficient exertion, allow the body to rest before it is entirely exhausted. When exhausted, some argue that they need stimulants in the shape of tea, coffee, spirituous liquors, tobacco, or some of those narcotic substances which are often taken to goad on the lagging powers to greater exertions. But instead of these kind of stimulants they should recruit by rest. Work less, wear less, eat less, and we shall be a great deal wiser, healthier, and wealthier people than by taking the course we now do. It is difficult to find anything more healthy to drink than good cold water, such as flows down to us from springs and snows of our mountains. This is the beverage we should drink. It should be our drink at all times. If we constantly drink even malt liquor made from our barley and wheat, our health would be injured more or less thereby. It may be remarked that some men who use spirituous liquors and tobacco are healthy, but I argue that they would be much more healthy if they did not use it, and then they are entitled to the blessings promised to those who observe the advice given in the "Word of Wisdom." Some few persons who have been addicted to the use of hot drinks, etc. have reached the age of eighty, eighty-three, and eighty-four years, but had they not been addicted to such habits of living they might have reached the age of an hundred or an hundred and five years. 12:122.

I do not mean to go without food and go to fasting. This is the other extreme. A sufficient amount of food that will agree with the-stomach is healthy, and should be partaken of. Aged or middle aged, youth or children, never should go without food until their stomachs are faint, demanding something to sustain their systems, and continue to undergo this; for this lays the foundation of weakness, and this weakness will tempt disease. But keep the stomach in a perfectly healthy condition. Now I do not mean fasting, but eating moderately; and if my sisters will go home and commence to adopt this rule, you will find that you begin to get better, your children and neighbors will get better. We do not expect all to be free from sickness. I have had a great deal of sickness in my life. I do not expect to be free from the ills, the weakness, debility and disease that prey upon the human family, but we can amend our ways, and amend our life by being prudent; and I wish the sisters to understand this, and to adopt these instructions. 19:68.

The citizens of this city are tolerably comfortable; a great many of them have an abundance of fruit, and they enjoy it. It is very healthy for them and their children to eat in the season thereof. 11:141.

As we got richer and built warm houses, and have lived more richly, indulging in sweet cake, plum pudding, roast beef and so on, we have had more or less disease among us. 13:132.
