Do not be wise in your own eyes; fear the Lord [with reverent awe and obedience] and turn [entirely] away from evil. It will be health to your body [your marrow, your nerves, your sinews, your muscles—all your inner parts] and refreshment (physical well-being) to your bones" (Proverbs 3:7-8).
From the beginning our Creator designed the physical frame to thrive and prosper in every area of life. Every minute of every day the existence of our being, the embodiment of spirit, soul, and body cries out with starvation. For information and demands sustainance for optimal health. "I want to live and feel good. What life sustaining nutrients will you give me today?"
Even though we sometimes fail to hear, or may veer from the right path, these three mighty warriors will rise up in defense of existence. And our body's immune system struggles to persevere under the pressures of life, to bring continual healing.
It's not until we fully turn and begin to walk in God's life sustaining Word; His principles and commands, that the restoration process becomes complete. Then we're afforded the abundnat life and divine health that our loving Creator God intended from the very beginning.
The Garden of Eden is where His omnipotence was amazing in the construction of the human frame: the spirit (our heart, inner person) that is created in God's own image; the soul (our mind, will, & emotions) that make life decisions; and the body (our physical flesh) that is created from the same elements as the earth (the dust); which is also the weakest of the three.
