"But what about an impoverished diet? I have spoken of the importance of the quantity and quality of food being in strict accordance with the laws of health. But we would not recommend an impoverished diet. I have been shown that many take a wrong view of the health reform and adopt too poor a diet. They subsist upon a cheap, poor quality of food, prepared without care or reference to the nourishment of the system. It is important that the food should be prepared with care, that the appetite, when not perverted, can relish it. Because we from principle discard the use of meat, butter, mince pies, spices, lard, and that which irritates the stomach and destroys health, the idea should never be given that it is of but little consequence what we eat. 2T 367.1"
"Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God."
The EGW passage directly addresses the principle of doing all things, including eating, with proper consideration and not to excess, aligning with the verse's call to glorify God in all actions.
"actions, instead of having dug down to the bottom and built upon a right foundation for yourself, you are walking in the sparks kindled by somebody else. And you will fail in this, as you have failed in the health reform. Now, if you had moved from principle you would not have done this. 2T 367.2"
"And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand:"
The EGW passage uses the metaphor of building on a foundation to illustrate the importance of establishing a correct foundation of principle, which parallels the warning in Matthew about building on sand.
