"Our preachers are not particular enough in regard to their habits of eating. They partake of too large quantities of food and of too great a variety at one meal. Some are reformers only in name. They have no rules by which to regulate their diet, but indulge in eating fruit or nuts between their meals, and thus impose too heavy burdens upon the digestive organs. Some eat three meals a day, when two would be more conducive to physical and spiritual health. If the laws which God has made to govern the physical system are violated, the penalty must surely follow. 4T 416.3"
"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?"
The EGW passage discusses the importance of healthy eating habits and respecting the physical body, which aligns with the principle in 1 Corinthians 6:19 that the body is a temple of the Holy Spirit.
