Every day men in positions of trust have decisions to make upon which depend results of great importance. Often they have to think rapidly, and this can be done successfully by those only who practice strict temperance. The mind strengthens under the correct treatment of the physical and mental powers. If the strain is not too great, new vigor comes with every taxation. But often the work of those who have important plans to consider and important decisions to make is affected for evil by the results of improper diet. A disordered stomach produces a disordered, uncertain state of mind. Often it causes irritability, harshness, or injustice. Many a plan that would have been a blessing to the world has been set aside, many unjust, oppressive, even cruel measures have been carried, as the result of diseased conditions due to wrong habits of eating.
“Here is a suggestion for all whose work is sedentary or chiefly mental; let those who have sufficient moral courage and self-control try it: At each meal take only two or three kinds of simple food, and eat no more than is required to satisfy hunger. Take active exercise every day, and see if you do not receive benefit.
“Strong men who are engaged in active physical labor are not compelled to be as careful as to the quantity or quality of their food as are persons of sedentary habits; but even these would have better health if they would practice self-control in eating and drinking.
“Some wish that an exact rule could be prescribed for their diet. They overeat, and then regret it, and so they keep thinking about what they eat and drink. This is not as it should be. One person cannot lay down an exact rule for another. Everyone should exercise reason and self-control, and should act from principle.
“Our bodies are Christ’s purchased possession, and we are not at liberty to do with them as we please. All who understand the laws of health should realize their obligation to obey these laws which God has established in their being. Obedience to the laws of health is to be made a matter of personal duty. We ourselves must suffer the results of violated law. We must individually answer to God for our habits and practices. Therefore the question with us is not, ‘What is the world’s practice?’ but, ‘How shall I as an individual treat the habitation that God has given me?’ ” The Ministry of Healing, 309, 310.
“Men and women cannot violate natural law by indulging depraved appetite and lustful passions, and not violate the law of God. Therefore He has permitted the light of health reform to shine upon us, that we may see our sin in violating the laws which He has established in our being. All our enjoyment or suffering may be traced to obedience or transgression of natural law. Our gracious heavenly Father sees the deplorable condition of men, who, some knowingly but many ignorantly, are living in violation of the laws that He has established. And in love and pity to the race, He causes the light to shine upon health reform. He publishes His law, and the penalty that will follow the transgression of it, that all may learn, and be careful to live in harmony with natural law. He proclaims His law so distinctly, and makes it so prominent, that it is like a city set on a hill. All accountable beings can understand it if they will. Idiots will not be responsible. To make plain natural law, and urge the obedience of it, is the work that accompanies the Third Angel’s Message, to prepare a people for the coming of the Lord.” Counsels on Diet and Foods, 69.
