"Tea and coffee, condiments, confectionery, and pastries are all active causes of indigestion. Flesh food also is harmful. Its naturally stimulating effect should be a sufficient argument against its use; and the almost universally diseased condition of animals makes it doubly objectionable. It tends to irritate the nerves and to excite the passions, thus giving the balance of power to the lower propensities. Ed 203.1"
"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 caring for the body as a temple. EGW expands on specific ways to care for the body, while Paul gives the general principle.
"I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service."
Both passages encourage presenting the body in a way that is pleasing to God. EGW specifies dietary practices, while Paul speaks of the body as a living sacrifice.
"Those who accustom themselves to a rich, stimulating diet, find after a time that the stomach is not satisfied with simple food. It demands that which is more and more highly seasoned, pungent, and stimulating. As the nerves become disordered and the system weakened, the will seems powerless to resist the unnatural craving. The delicate coating of the stomach becomes irritated and inflamed until the most stimulating food fails of giving relief. A thirst is created that nothing but strong drink will quench. Ed 203.2"
"Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?"
Both passages discuss the concept of being enslaved to something. EGW discusses being enslaved to unhealthy cravings, while Paul speaks of being enslaved to sin or obedience.
"apparently small deviations from the right should be made very plain. Let the student be taught the value of a simple, healthful diet in preventing the desire for unnatural stimulants. Let the habit of self-control be early established. Let the youth be impressed with the thought that they are to be masters, and not slaves. Of the kingdom within them God has made them rulers, and they are to exercise their Heaven-appointed kingship. When such instruction is faithfully given, the results will extend far beyond the youth themselves. Influences will reach out that will save thousands of men and women who are on the very brink of ruin. Ed 203.3"
"And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible."
Both passages emphasize self-control and mastery over desires. 1 Corinthians 9:25 speaks of athletes training with temperance to win a crown, while EGW speaks of self-control in diet and habits to rule the 'kingdom within.'
