"There was among us One who presented this matter very clearly and with the utmost simplicity. He told us that it would be a mistake to establish a sanitarium within the city limits. A sanitarium should have the advantage of plenty of land, so that the invalids can work in the open air. For nervous, gloomy, feeble patients, outdoor work is invaluable. Let them have flower beds to care for. In the use of rake and hoe and spade they will find relief for many of their maladies. Idleness is the cause of many diseases. 7T 85.2"
"In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return."
Both passages connect work/labor with well-being. Genesis 3:19 speaks of labor as a consequence of the fall, while EGW presents it as beneficial for health, but both acknowledge the connection between physical exertion and life.
"Life in the open air is good for body and mind. It is God's medicine for the restoration of health. Pure air, good water, sunshine, the beautiful surroundings of nature—these are His means for restoring the sick to health in natural ways. To the sick it is worth more than silver or gold to lie in the sunshine or in the shade of the trees. 7T 85.3"
"He causeth the grass to grow for the cattle, and herb for the service of man: that he may bring forth food out of the earth;"
Both passages highlight God's provision of natural elements (grass/herbs in Psalms, air/water/sunshine in EGW) for the benefit and well-being of humans.
