"“Know ye not that your bodies are the members of Christ?” “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.” 1 Corinthians 6:15, 19, 20 . Our bodies are Christ's purchased property, and we are not at liberty to do with them as we please. Man has done this. He has treated his body as if its laws had no penalty. Through perverted appetite its organs and powers have become enfeebled, diseased, and crippled. And these results which Satan has brought about by his own specious temptations he uses to taunt God with. He presents before God the human body that Christ has purchased as His property, and what an unsightly representation of his Maker man is! Because man has sinned against his body and has corrupted his ways, God is dishonored. 6T 369.2"
"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?"
The EGW passage directly quotes 1 Corinthians 6:19 and references 6:15 and 6:20, making it a clear and explicit allusion. The surrounding text further elaborates on the implications of this verse for physical health and glorifying God in the body.
"When men and women are truly converted, they will conscientiously regard the laws of life that God has established in their being, thus seeking to avoid physical, mental, and moral feebleness. Obedience to these laws must be made a matter of personal duty. We ourselves must suffer the ills of violated law. We must answer to God for our habits and practices. Therefore the question for us is not, “What will the world say?” but, “How shall I, claiming to be a Christian, treat the habitation God has given me? Shall I work for my highest temporal and spiritual good by keeping my body as a temple for the indwelling of the Holy Spirit, or shall I sacrifice myself to the world's ideas and practices?” 6T 369.3"
"For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s."
The EGW passage directly echoes the sentiment of glorifying God in one's body, connecting it to the idea of the body as a temple and the importance of health. It amplifies the principle found in 1 Corinthians 6:20.
