"In the study of hygiene the earnest teacher will improve every opportunity to show the necessity of perfect cleanliness both in personal habits and in all one's surroundings. The value of the daily bath in promoting health and in stimulating mental action, should be emphasized. Attention should be given also to sunlight and ventilation, the hygiene of the sleeping room and the kitchen. Teach the pupils that a healthful sleeping room, a thoroughly clean kitchen, and a tastefully arranged, wholesomely supplied table, will go further toward securing the happiness of the family and the regard of every sensible visitor than any amount of expensive furnishing in the drawing room. That “the life is more than meat, and the body is more than raiment” ( Luke 12:23 ), is a lesson no less needed now than when given by the divine Teacher eighteen hundred years ago. Ed 200.1"
"The life is more than meat, and the body is more than raiment."
Ellen White directly references Luke 12:23 in this passage.
"facts and principles. This alone will prove of little benefit. He may understand the importance of ventilation, his room may be supplied with pure air; but unless he fills his lungs properly he will suffer the results of imperfect respiration. So the necessity of cleanliness may be understood, and needful facilities may be supplied; but all will be without avail unless put to use. The great requisite in teaching these principles is to impress the pupil with their importance so that he will conscientiously put them in practice. Ed 200.2"
"But be ye doers of the word, and not hearers only, deceiving your own selves."
Both passages emphasize the importance of being a 'doer' and not just a 'hearer' or knower. James 1:22 is a direct command to act on what one knows. EGW stresses that understanding principles is useless without putting them into practice. This is a strong and direct parallel.
"By a most beautiful and impressive figure, God's word shows the regard He places upon our physical organism and the responsibility resting on us to preserve it in the best condition: “Know ye not that your body is a temple of the Holy Spirit which is in you, which ye have from God? and ye are not your own.” “If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are.” 1 Corinthians 6:19 , R.V., margin; 3:17 . Ed 200.3"
"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?"
Ellen White directly references 1 Corinthians 6:19 in this passage.
