Many have expected that God would keep them from sickness merely because they have asked Him to do so. But God did not regard their prayers, because their faith was not made perfect by works. God will not work a miracle to keep those from sickness who have no care for themselves, but are continually violating the laws of health and make no efforts to prevent disease. When we do all we can on our part to have health, then may we expect that the blessed results will follow, and we can ask God in faith to bless our efforts for the preservation of health. He will then answer our prayer, if His name can be glorified thereby. But let all understand that they have a work to do. God will not work in a miraculous manner to preserve the health of persons who by their careless inattention to the laws of health are taking a sure course to make themselves sick.

In order to have good blood, we must breathe well. Full, deep inspirations of pure air which fill the lungs with oxygen, purify the blood. They impart to it a bright color, and send it, a life-giving current, to every part of the body. A good respiration soothes the nerves; it stimulates the appetite and renders digestion more perfect; and it induces sound, refreshing sleep.—The Ministry of Healing, 272 (1905).

Many have been taught from childhood that night air is positively injurious to health, and therefore must be excluded from their rooms. To their own injury they close the windows and doors of their sleeping apartments, to protect themselves from the night air which they say is so dangerous to health. In this they are deceived. In the cool of the evening it may be necessary to guard from chilliness by extra clothing; but they should give their lungs air.... Many are suffering from disease because they refuse to receive into their rooms at night the pure night air. The free, pure air of heaven is one of the richest blessings we can enjoy.—Testimonies for the Church 2:527, 528 (1870).
