Counsels On Diets And Foods.

64. Those who bring disease upon themselves, by self-gratification, have not healthy bodies and minds. They cannot weigh the evidences of truth, and comprehend the requirements of God. Our Saviour will not reach His arm low enough to raise such from their degraded state, while they persist in pursuing a course to sink themselves still lower. {CD 49.3}

All are required to do what they can to preserve healthy bodies and sound minds. If they will gratify a gross appetite, and by so doing blunt their sensibilities, and becloud their perceptive faculties so that they cannot appreciate the exalted character of God, or delight in the study of His word, they may be assured that God will not accept their unworthy offering any sooner than that of Cain. God requires them to cleanse themselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of the Lord. After man has done all in his power to ensure health, by the denying of appetite and gross passions, that he may possess a healthy mind, and a sanctified imagination, that he may render to God an offering in righteousness, then he is saved alone by a miracle of God’s mercy, as was the ark upon the stormy billows. Noah had done all that God required of him in making the ark secure; then God performed that which man could not do, and preserved the ark by His miraculous power.—Spiritual Gifts 4a:148, 149, 1864 {CD 49.4}
