"The influence of the mind on the body, as well as of the body on the mind, should be emphasized. The electric power of the brain, promoted by mental activity, vitalizes the whole system, and is thus an invaluable aid in resisting disease. This should be made plain. The power of the will and the importance of self-control, both in the preservation and in the recovery of health, the depressing and even ruinous effect of anger, discontent, selfishness, or impurity, and, on the other hand, the marvelous life-giving power to be found in cheerfulness, unselfishness, gratitude, should also be shown. Ed 197.2"
"A merry heart doeth good like a medicine: but a broken spirit drieth the bones."
EGW's statement about cheerfulness and its life-giving power is a clear allusion to Proverbs 17:22, which states that a merry heart is like medicine.

Ed 197.4"

"life.” Psalm 36:9 . Not only is He the originator of all, but He is the life of everything that lives. It is His life that we receive in the sunshine, in the pure, sweet air, in the food which builds up our bodies and sustains our strength. It is by His life that we exist, hour by hour, moment by moment. Except as perverted by sin, all His gifts tend to life, to health and joy. Ed 197.5"
