We should consider the words of the apostle Paul, in which he appeals to his brethren, by the mercies of God, to present their bodies “a living sacrifice, holy, acceptable unto God.” ... Sanctification is not merely a theory, an emotion, or a form of words, but a living, active principle, entering into the everyday life. It requires that our habits of eating, drinking, and dressing be such as to secure the preservation of physical, mental, and moral health, that we may present to the Lord our bodies—not an offering corrupted by wrong habits but—“a living sacrifice, holy, acceptable unto God.” Romans 12:1. CH 67.1
Let none who profess godliness regard with indifference the health of the body, and flatter themselves that intemperance is no sin and will not affect their spirituality. A close sympathy exists between the physical and the moral nature. The standard of virtue is elevated or degraded by the physical habits. Excessive eating of the best of food will produce a morbid condition of the moral feelings. And if the food is not the most healthful, the effects will be still more injurious. Any habit which does not promote healthful action in the human system degrades the higher and nobler faculties. Wrong habits of eating and drinking lead to errors in thought and action. Indulgence of appetite strengthens the animal propensities, giving them the ascendancy over the mental and spiritual powers. CH 67.2
“Abstain from fleshly lusts, which war against the soul” (1 Peter 2:11), is the language of the apostle Peter. Many regard this warning as applicable only to the licentious; but it has a broader meaning. It guards against every injurious gratification of appetite or passion. It is a most forcible warning against the use of such stimulants and narcotics as tea, coffee, tobacco, alcohol, and morphine. These indulgences may well be classed among the lusts that exert a pernicious influence upon moral character. The earlier these hurtful habits are formed, the more firmly will they hold their victims in slavery to lust, and the more certainly will they lower the standard of spirituality. CH 67.3
Bible teaching will make but a feeble impression upon those whose faculties are benumbed by indulgence of appetite. Thousands will sacrifice not only health and life, but their hope of heaven, before they will wage war against their own perverted appetites. One lady, who for many years claimed to be sanctified, made the statement that if she must give up her pipe or heaven she would say, “Farewell, heaven; I cannot overcome my love for my pipe.” This idol had been enshrined in the soul, leaving to Jesus a subordinate place. Yet this woman claimed to be wholly the Lord's! CH 68.1
Wherever they may be, those who are truly sanctified will elevate the moral standard by preserving correct physical habits, and, like Daniel, presenting to others an example of temperance and self-denial. Every depraved appetite becomes a warring lust. Everything that conflicts with natural law creates a diseased condition of the soul. The indulgence of appetite produces a dyspeptic stomach, a torpid liver, a clouded brain, and thus perverts the temper and the spirit of the man. And these enfeebled powers are offered to God, who refused to accept the victims for sacrifice unless they were without a blemish. It is our duty to bring our appetite and our habits of life into conformity to natural law. If the bodies offered upon Christ's altar were examined with the close scrutiny to which the Jewish sacrifices were subjected, who with our present habits would be accepted? CH 68.2
With what care should Christians regulate their habits, that they may preserve the full vigor of every faculty to give to the service of Christ. If we would be sanctified in soul, body, and spirit, we must live in conformity to the divine law. The heart cannot preserve consecration to God while the appetites and passions are indulged at the expense of health and life.... CH 69.1
Paul's inspired warnings against self-indulgence are sounding along the line down to our time.... He presents for our encouragement the freedom enjoyed by the truly sanctified. “There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.” Romans 8:1. He charges the Galatians to “walk in the Spirit, and ye shall not fulfill the lust of the flesh. For the flesh lusteth against the Spirit, and the Spirit against the flesh.” Galatians 5:16, 17. He names some of the forms of fleshly lusts—idolatry, drunkenness, and such like. After mentioning the fruits of the Spirit, among which is temperance, he adds, “And they that are Christ's have crucified the flesh with the affections and lusts.” Verse 24. CH 69.2
There are many among professed Christians today who would decide that Daniel was too particular and would pronounce him narrow and bigoted. They consider the matter of eating and drinking of too little consequence to require such a decided stand—one involving the probable sacrifice of every earthly advantage. But those who reason thus will find in the day of judgment that they turned from God's express requirements and set up their own opinion as a standard of right and wrong. They will find that what seemed to them unimportant was not so regarded of God. His requirements should be sacredly obeyed. Those who accept and obey one of His precepts because it is convenient to do so, while they reject another because its observance would require a sacrifice, lower the standard of right, and by their example lead others to lightly regard the holy law of God. “Thus saith the Lord” is to be our rule in all things. CH 69.3
