"Chapter 18—Mind Cure The relation that exists between the mind and the body is very intimate. When one is affected, the other sympathizes. The condition of the mind affects the health to a far greater degree than many realize. Many of the diseases from which men suffer are the result of mental depression. Grief, anxiety, discontent, remorse, guilt, distrust, all tend to break down the life forces and to invite decay and death. MH 241"
"A merry heart doeth good like a medicine: but a broken spirit drieth the bones."
Both passages highlight the connection between mental and physical health. The EGW passage elaborates on how negative emotions can lead to disease, while Proverbs 17:22 contrasts a merry heart with a broken spirit. The connection is strong and relevant.
"Keep thy heart with all diligence; for out of it are the issues of life."
The proverb speaks of guarding the heart because it determines the course of life. EGW expands on this principle by detailing how mental states (grief, anxiety, etc.) directly impact physical health, which aligns with the 'issues of life' stemming from the heart/mind.
"Disease is sometimes produced, and is often greatly aggravated, by the imagination. Many are lifelong invalids who might be well if they only thought so. Many imagine that every slight exposure will cause illness, and the evil effect is produced because it is expected. Many die from disease the cause of which is wholly imaginary. MH 241.2"
"For as he thinketh in his heart, so is he: Eat and drink, saith he to thee; but his heart is not with thee."
The proverb states that a man is as he thinks in his heart. EGW directly applies this principle to health, stating that imagination and expectation can produce or aggravate disease. This is a direct application of the proverb's principle.
"Courage, hope, faith, sympathy, love, promote health and prolong life. A contented mind, a cheerful spirit, is health to the body and strength to the soul. “A merry [rejoicing] heart doeth good like a medicine.” Proverbs 17:22 . MH 241.3"
"A merry heart doeth good like a medicine: but a broken spirit drieth the bones."
Ellen White directly references Proverbs 17:22 in this passage.
"Pleasant words are as an honeycomb, sweet to the soul, and health to the bones."
EGW directly quotes Proverbs 17:22 and connects it to the positive effects of mental states on health, which is the same theme as Proverbs 16:24. While not a direct quote, the thematic connection is strong and EGW explicitly references the proverb.
"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. MH 241.4"
"A merry heart doeth good like a medicine: but a broken spirit drieth the bones."
EGW directly applies the principle of Proverbs 17:22 (a merry heart is like medicine) to the treatment of the sick, emphasizing the importance of mental influence in combating disease. This is a clear and direct application of the proverb's principle.
