"taking a full inspiration of air at every sentence, and throwing out the words by exercising the abdominal muscles. If they will observe this simple rule, giving attention to the laws of health in other respects, they may preserve their life and usefulness much longer than men in any other profession. The chest will become broader, and ...the speaker need seldom become hoarse, even by constant speaking. Instead of becoming consumptives, ministers may, by exercising care, overcome all tendency to consumption. GW 90.1"
"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? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s."
Both passages emphasize the importance of taking care of one's body. 1 Corinthians 6:19-20 states that the body is a temple of the Holy Spirit and should be used to glorify God. The EGW passage discusses specific ways ministers can care for their bodies to prolong their lives and usefulness in ministry. The connection is thematic, not a direct quote or allusion.
"Unless ministers educate themselves to speak in accordance with physical law, they will sacrifice life, and many will mourn the loss of “those martyrs to the cause of truth;” when the facts in the case are, that by indulging in wrong habits, they did injustice to themselves and to the truth which they represented, and robbed God and the world of the service they might have rendered. God would have been pleased to have them live, but they slowly committed suicide. GW 90.2"
"My people are destroyed for lack of knowledge: because thou hast rejected knowledge, I will also reject thee, that thou shalt be no priest to me: seeing thou hast forgotten the law of thy God, I will also forget thy children."
Both passages deal with the consequences of neglecting knowledge and its impact on service to God. Hosea 4:6 speaks of destruction due to a lack of knowledge, while the EGW passage discusses ministers shortening their lives and diminishing their service due to neglecting physical laws. The connection is thematic, focusing on the negative consequences of neglecting important knowledge.
