"The practice of eating but two meals a day is generally found a benefit to health; yet under some circumstances persons may require a third meal. This should, however, if taken at all, be very light, and of food most easily digested. “Crackers”—the English biscuit—or zwieback, and fruit, or cereal coffee, are the foods best suited for the evening meal. MH 321.1"
"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."
The EGW quote provides specific dietary recommendations based on the principle of caring for the body as a temple of the Holy Spirit, although it is not a direct quote or explicit allusion.
"Some are continually anxious lest their food, however simple and healthful, may hurt them. To these let me say, Do not think that your food will injure you; do not think about it at all. Eat according to your best judgment; and when you have asked the Lord to bless the food for the strengthening of your body, believe that He hears your prayer, and be at rest. MH 321.2"
"For every creature of God is good, and nothing to be refused, if it be received with thanksgiving: For it is sanctified by the word of God and prayer."
The EGW passage directly echoes the sentiment of 1 Timothy 4:4-5, encouraging believers to receive food with thanksgiving and prayer, trusting in God's blessing. The connection is strong and clear.
"Therefore I say unto you, Take no thought for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than meat, and the body than raiment?"
Both passages address anxiety about food and encourage trust in God's provision. EGW's counsel to not worry about food and to trust in God's blessing echoes the sentiment in Matthew 6:25.
"Because principle requires us to discard those things that irritate the stomach and impair health, we should remember that an impoverished diet produces poverty of the blood. Cases of disease most difficult to cure result from this cause. The system is not sufficiently nourished, and dyspepsia and general debility are the result. Those who use such a diet are not always compelled by poverty to do so, but they choose it through ignorance or negligence, or to carry out their erroneous ideas of reform. MH 321.3"
"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? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s."
This passage speaks directly to the principle of honoring God with our bodies, which includes taking care of our health through proper nourishment, as the target passage discusses the consequences of an impoverished diet.
