Proverbs 17:22 A merry heart doeth good like a medicine: but a broken spirit drieth the bones.
[1MCP pp362] Depressing Emotions are Injurious to Health. It is the duty of everyone to cultivate cheerfulness instead of brooding over sorrow and troubles. Many not only make themselves wretched in this way, but they sacrifice health and happiness to a morbid imagination. There are things in their surroundings that are not agreeable, and their countenances wear a continual frown that more plainly than words expresses discontent.
These depressing emotions are a great injury to them health-wise, for by hindering the process of digestion they interfere with nutrition. While grief and anxiety cannot remedy a single evil, they can do great harm; but cheerfulness and hope, while they brighten the pathway of others, “are life unto those that find them, and health to all their flesh” (Proverbs 4:22).
In Treating Sick, Study Minds [See Chapter 42, Mind and Health.]—In the treatment of the sick the effect of mental influence should not be overlooked. Rightly used, this influence affords one of the most effective agencies for combating disease. A great deal of the sickness which afflicts humanity has its origin in the mind and can only be cured by restoring the mind to health.
Isaiah 26:3 Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee.
May God add His blessing to the study of His word. “Good night” and God bless!
