"The obligation resting upon us to keep the body in health is an individual responsibility. The Lord requires each one to work out his salvation day by day. He bids us reason from cause to effect, to remember that we are His property, and to unite with Him in keeping the body pure and healthy, and the whole being sanctified to Him. CT 300.1"
"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."
EGW's statement about keeping the body healthy as an individual responsibility and uniting with God to keep the body pure and healthy echoes the principle in 1 Corinthians 6:19-20, which states that our bodies are temples of the Holy Spirit and we are not our own, but bought with a price, therefore we should glorify God in our bodies.
"guiltless those who treat lightly His precious gifts. Men should realize that the greater their endowment of strength, of talent, of means, or of opportunities, the more heavily should the burden of God's work rest upon them, and the more they should do for Him. The youth who are trained to believe that life is a sacred trust will hesitate to plunge into the vortex of dissipation and crime that swallows up so many promising young men of this age. CT 300.2"
"But he that knew not, and did commit things worthy of stripes, shall be beaten with few stripes. For unto whomsoever much is given, of him shall be much required: and to whom men have committed much, of him they will ask the more."
EGW's statement about the greater the endowment, the more should be done for God, directly reflects the principle in Luke 12:48, which states that to whomsoever much is given, of him shall be much required.
"***** The teacher whose physical powers are already enfeebled by disease or overwork should pay especial attention to the laws of health. He should take time for recreation. When a teacher sees that his health is not sufficient to stand the pressure of heavy study, he should heed the admonition of nature and lighten the load. He should not take upon himself responsibilities outside of his schoolwork which will so tax him physically and mentally that his nervous system will be unbalanced, for by this course he will be unfitted to deal with minds and cannot do justice either to himself or to his students. CT 300.3"
"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? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s."
The verse speaks to the body being a temple and glorifying God in it. EGW applies this principle to teachers, urging them to care for their health to effectively serve, which aligns with glorifying God in their bodies.
