"Let physicians and nurses draw from the things of nature, lessons teaching of God. Let them point the patients to Him whose hand has made the lofty trees, the grass, and the flowers, encouraging them to see in every bud and flower an expression of His love for His children. He who cares for the birds and the flowers will care for the beings formed in His own image. MH 266.1"
"Behold the fowls of the air: for they sow not, neither do they reap, nor gather into barns; yet your heavenly Father feedeth them. Are ye not much better than they?"
Both passages use the example of God's care for nature (birds and flowers) to illustrate His care for humanity. EGW expands on this theme, applying it specifically to healing and encouraging patients to find comfort in God's creation.
