"he takes but little exercise in the open air, does himself an injury. A proportionate exercise of the various organs and faculties of the body is essential to the best work of each. When the brain is constantly taxed while the other organs are left inactive, there is a loss of physical and mental strength. The physical powers are robbed of their healthy tone, the mind loses its freshness and vigor, and a morbid excitability is the result. CT 295.2"
"What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s."
Both passages emphasize the importance of caring for the body as a temple. EGW expands on the practical implications of this principle, specifically mentioning the need for exercise and balance.
"A merry heart doeth good like a medicine: but a broken spirit drieth the bones."
Both passages connect physical and mental well-being. While Proverbs focuses on the emotional aspect ('merry heart'), EGW discusses the impact of physical activity on mental freshness and vigor. There's a clear thematic overlap regarding the interconnectedness of mind and body.
"In order for men and women to have well-balanced minds, all the powers of the being should be called into use and developed. There are in this world many who are one-sided because only one set of faculties has been cultivated, while others are dwarfed from inaction. The education of many youth is a failure. They overstudy, while they neglect that which pertains to the practical life. That the balance of the mind may be maintained, a judicious system of physical work should be combined with mental work that there may be a harmonious development of all the powers. CT 295.3"
"For the body is not one member, but many."
Both passages emphasize the importance of balance and the interconnectedness of different parts. 1 Corinthians 12:14 uses the analogy of the body to illustrate the need for diverse members in the church, while EGW applies this principle to the development of various faculties within an individual. The underlying theme of holistic development is present in both.
