A negative state of mind can have a negative effect on the body, but if we can counter that negativity, we will find peace of mind, which will reduce stress on vital organs and promote health. This is why peaceful meditation, positive attitudes, and concentrating on good thoughts have a good effect on both mind and body. “Whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report, if there is any virtue and if there is anything praiseworthy—meditate on these things.”
The Bible also tells us repeatedly not to worry or be fearful, but rather to ask God to work things out and to trust that He will. “Be strong and of good courage; do not be afraid, nor be dismayed, for the Lord your God is with you wherever you go.” “God is our refuge and strength, a very present help in trouble. Therefore we will not fear, even though the earth be removed, and though the mountains be carried into the midst of the sea.” “In God I have put my trust; I will not be afraid.” “Peace I leave with you, My peace I give to you; not as the world gives do I give to you. Let not your heart be troubled, neither let it be afraid.” “Do not be afraid; only believe.”
Faith in God gives you peace of mind, contentment of heart, and a sense of spiritual well-being—all of which tend to greatly improve your physical well-being.
