"You have flesh, but it is not good material. You are worse off for this amount of flesh. If you should each come down to a more spare diet, which would take from you twenty-five or thirty pounds of your gross flesh, you would be much less liable to disease. The eating of flesh meats has made a poor quality of blood and flesh. Your systems are in a state of inflammation, prepared to take on disease. You are liable to acute attacks of disease and to sudden death because you do not possess the strength of constitution to rally and resist disease. There will come a time when the strength and health you have flattered yourself you possessed will prove to be weakness. It is not the chief end of man to glorify his stomach. You have animal wants to be supplied; but because of this necessity shall man become all animal? 2T 61.1"
"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 taking care of one's body and not being controlled by physical desires. The EGW passage focuses on diet and its impact on health, while the Bible verse speaks of the body as a temple of the Holy Spirit and glorifying God through it.
You have set for your children a table of unwholesome food, cooked in an unhealthful manner. You have placed flesh meats before them, and what is the result? Are they refined, intellectual, obedient, conscientious, and religiously inclined? You know this is not the case, but entirely the contrary. Your manner of living has strengthened the animal of your nature and weakened the spiritual. You have transmitted to your children a miserable legacy, a depraved nature rendered still more depraved by your gross habits of eating and drinking. Your table has completed the work of making them what they are. The sin lies at your door. You know that they are not religiously inclined, that they will not submit to restraint, but are inclined to disobedience and to disrespect your authority. Your eldest son especially is corrupt, partaking to a great degree of the animal. Scarcely a trace of the divine can be seen in his organism. You have brought up your children to indulge their appetite when they…
"For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit."
Both passages contrast living according to the flesh (physical desires) versus living according to the Spirit (spiritual values). The EGW passage specifically links diet and upbringing to the development of either animalistic or spiritual tendencies in children, mirroring the broader principle in Romans.
