I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service. Romans 12:1.
We should preserve our strength to labor in the cause of God when our labor is needed. We should be careful not to take upon ourselves burdens that others can and should bear. We should encourage a cheerful, hopeful, peaceful frame of mind; for our health depends upon our so doing. The work that God requires us to do will not prevent our caring for our health, that we may recover from the effect of overtaxing labor. The more perfect our health, the more perfect will be our labor. When we overtax our strength, and become exhausted, we are liable to take cold, and at such times there is danger of disease assuming a dangerous form. We must not leave the care of ourselves with God, when He has placed that responsibility with us (Testimonies For The Church 3:13).
God created man a little lower than the angels and bestowed upon him attributes that will, if properly used, make him a blessing to the world and cause him to reflect the glory to the Giver. But although made in the image of God, man has, through intemperance, violated principle and God's law in his physical nature. Intemperance of any kind benumbs the perceptive organs and so weakens the brain-nerve power that eternal things are not appreciated, but placed upon a level with the common. The higher powers of the mind, designed for elevated purposes, are brought into slavery to the baser passions. If our physical habits are not right, our mental and moral powers cannot be strong; for great sympathy exists between the physical and the moral. The apostle Peter understood this and raised his voice of warning to his brethren: “Dearly beloved, I beseech you as strangers and pilgrims, abstain from fleshly lusts, which war against the soul.”
There is but little moral power in the professed Christian world. Wrong habits have been indulged, and physical and moral laws have been disregarded, until the general standard of virtue and piety is exceedingly low. Habits which lower the standard of physical health enfeeble mental and moral strength....
Those who have had the light upon the subjects of eating and dressing with simplicity in obedience to physical and moral laws, and who turn from the light which points out their duty, will shun duty in other things. If they blunt their consciences to avoid the cross which they will have to take up to be in harmony with natural law, they will, in order to shun reproach, violate the Ten Commandments.... There are many among professed Sabbathkeepers ... who are more firmly wedded to worldly fashions and lusts than they are to healthy bodies, sound minds, or sanctified hearts (Testimonies for the Church 3:50, 51).
