"Overstudy The student who desires to put the work of two years into one should not be permitted to have his own way. To undertake to do double work means, with many, overtaxation of the mind and neglect of physical exercise. It is not reasonable to suppose that the mind can assimilate an oversupply of mental food, and it is as great a sin to overload the mind as it is to overload the digestive organs. CT 296"
"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?"
Both passages relate to the idea of the body as a temple and the need to care for it. EGW applies this principle to the context of overstudy, arguing that overloading the mind is as harmful as overloading the digestive system. This is a direct application of the principle of bodily stewardship found in 1 Corinthians 6:19.
"Students should have manual work to do, and it will not hurt them if in doing this work they become weary. Do you not think that Christ became weary? Indeed He did. Weariness injures no one. It only makes rest the sweeter. The lesson cannot be too often repeated that education will be of little value without physical strength with which to use it. When students leave college, they should have better health and a better understanding of the laws of life than when they entered it. CT 296.1"
"Now Jacob’s well was there. Jesus therefore, being wearied with his journey, sat thus on the well: and it was about the sixth hour."
EGW explicitly mentions Christ's weariness, directly referencing the biblical account. She uses this example to normalize and even value physical exertion, connecting it to the sweetness of rest and the importance of physical strength.
