Self-indulgence and violation of natural and health laws cause disease and feebleness.

Original passage

Many persons bring disease upon themselves by their self-indulgence. They have not lived in accordance with natural law or the principles of strict purity. Others have disregarded the laws of health in their habits of eating and drinking, dressing, or working. Often some form of vice is the cause of feebleness of mind or body. Should these persons gain the blessing of health, many of them would continue to pursue the same course of heedless transgression of God's natural and spiritual laws, reasoning that if God heals them in answer to prayer, they are at liberty to continue their unhealthful practices and to indulge perverted appetite without restraint. If God were to work a miracle in restoring these persons to health, He would be encouraging sin.
