Tobacco, in whatever form it is used, tells upon the constitution. It is a slow poison. It affects the brain and benumbs the sensibilities, so that the mind cannot clearly discern spiritual things, especially those truths which would have a tendency to correct this filthy indulgence. Those who use tobacco in any form are not clear before God. In such a filthy practice it is impossible for them to glorify God in their bodies and spirits which are His. And while they are using slow and sure poisons, which are ruining their health and debasing the faculties of the mind, God cannot approbate them. He may be merciful to them while they indulge in this pernicious habit in ignorance of the injury it is doing them, but when the matter is set before them in its true light, then they are guilty before God if they continue to indulge this gross appetite.
(CH 81.1)
God required the children of Israel to observe habits of strict cleanliness. In any case of the least impurity they were to remain out of the camp until evening, then to wash themselves and come into the camp. There was not a tobacco user in that vast army. If there had been, he would have been required to choose to remain out of the camp or cease the use of the filthy weed. And after cleansing his mouth from the least of its filthy remains, he might have been permitted to mingle with the congregation of Israel.
(CH 81.2)
Tobacco Defilement an Offense to God
The priests, who ministered in sacred things, were commanded to wash their feet and their hands before entering the tabernacle in the presence of God to importune for Israel, that they might not desecrate the sanctuary. If the priests had entered the sanctuary with their mouths polluted with tobacco, they would have shared the fate of Nadab and Abihu. And yet professed Christians bow before God in their families to pray with their mouths defiled with the filth of tobacco....
(CH 81.3)
Strict Cleanliness Required
Men who have been set apart by the laying on of hands, to minister in sacred things, often stand in the desk with their mouths polluted, their lips stained, and their breath tainted with the defilements of tobacco. They speak to the people in Christ’s stead. How can such a service be acceptable to a holy God, who required the priests of Israel to make such special preparations before coming into His presence, lest His sacred holiness should consume them for dishonoring Him, as in the case of Nadab and Abihu? These may be assured that the mighty God of Israel is still a God of cleanliness. They profess to be serving God while they are committing idolatry, by making a God of their appetite. Tobacco is their cherished idol. To it every high and sacred consideration must bow. They profess to be worshiping God, while at the same time they are violating the first commandment. They have other gods before the Lord. “Be ye clean, that bear the vessels of the Lord.” Isaiah 52:11.
(CH 82.1)
God requires purity of heart and personal cleanliness now, as when He gave the special directions to the children of Israel. If God was so particular to enjoin cleanliness upon those journeying in the wilderness, who were in the open air nearly all the time, He requires no less of us who live in ceiled houses, where impurities are more observable and have a more unhealthful influence.
