Those who understand physiology and hygiene will, in their ministerial labor, find it a means whereby they may enlighten others in regard to the proper and intelligent treatment of the physical, mental, and moral powers. Therefore those who are preparing for the ministry should make a diligent study of the human organism, that they may know how to care for the body, not by means of drugs, but from nature’s own laboratory. The Lord will bless those who make every effort to keep themselves free from disease and lead others to regard as sacred the health of the body as well as of the soul. {6T 302.1}

(302) Dem som forstår fysiologi og hygiejne vil, i deres embede, finde det som et middel hvorved de kan oplyse andre om ordentlig og forstandsmæssig omgang med fysiske, mentale og moralske kræfter. Derfor bør dem som forbereder sig for prædikantgerninger studere menneskeorganismen omhyggeligt, så de ved hvordan de skal sørge for kroppen, ikke ved hjælp af stimulanser, men fra naturens egen laboratorium. Herren vil velsigne dem, som gør alt for at holde sig selv frie fra sygdomme og få andre til at tage sig ligeså meget af legemets sundhed som af sjælens sundhed.
