3rd John 1:2 Beloved, I wish above all things that thou mayest prosper and be in health, even as your soul prospers.
In the above passage we find not merely a wish for good health, we also discover that there is a close relation between the spiritual and physical aspects of our being. Whatever affects the body also affects the mind, and vice versa, hence the reason why the passage links the prosperity of the soul with that of the body.
When a person is stressed out mentally, the effects can be seen in their person, for the mind is a part of the body, and whenever one part hurts the other is also adversely affected. The same is true when the body is in health. The mental, and spiritual aspects reap the benefits too. A healthy body can enable the Christian to gain the victory, it can help with understanding deep truths, and it significantly alters one’s outlook on life, for there is a close symbiosis between the mind, body spiritual growth and development.
This is the reason why as soon as the Hebrews had crossed over Jordan God addressed the health issue because He knows that physical health is conducive to spiritual well-being and maturity. This does not mean that a sick saint cannot grow in grace, or must of necessity sin on account of his or her condition. All it means is that you will always be better off with a healthy mind and body, for the one who is sick in the physical might not be able to serve in his or her fullest capacity, as the one who is in health. These are just the bare facts in the matter.
Jeremiah 8:21 For the hurt of the daughter of my people am I hurt; I am black; astonishment hath taken hold on me. 22 Is there no balm in Gilead; is there no physician there? why then is not the health of the daughter of my people recovered?
May God add His blessing to the study of His word. “Good night” and God bless!
