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 3:17.
Perfection of character cannot be attained when the laws of nature are disregarded; for this is transgression of the law of God. His law is written by His own finger upon every nerve, every muscle, every fiber of our being, upon every faculty which has been entrusted to man. These gifts are bestowed, not to be abused and corrupted, but to be used to His honor and glory in the uplifting of humanity….
The relation that exists between mind and body is very intimate: when one is affected, the other is always more or less in sympathy. It is impossible for men, while under the power of sinful, health-destroying habits, to appreciate sacred truths. When the intellect is clouded, the moral powers are enfeebled, and sin does not look sinful. The most ennobling, grand, and glorious themes of God’s Word seem but idle tales. Satan can then easily snatch away the good seed that has been sown in the heart; for the soul is in no condition to comprehend or understand its true value. It is thus that selfish, health-destroying indulgences are counteracting the influence of the message which is to prepare a people for the great day of God.
We are living in a most solemn, awful moment of this earth’s history. Not a soul whose life is one of careless self-degradation, through transgression of physical laws, will stand in the great day of trial just before us. There is a terrible account to be rendered to God by those who have but little regard for the human body, and treat it ruthlessly…. True religion and the laws of health go hand in hand.31The Review and Herald, November 12, 1901.
The least departure from the strictest integrity under any circumstances because it is convenient, will harden the conscience and prepare the way for the violation of moral obligations in other ways. If we treat the health of the body, which is our highest earthly interest, without due consideration, we prepare the way for temptation and the violation of higher claims.32Letter 47a, 1874.
