I am currently reading the book from 1952 titled, The Power of Positive Thinking by Norman Vincent Peale. It is a terrific book and has many nuggets of wisdom, even for today (*especially for today!) Here is an excerpt from page 39:
“The longer I live the more I am convinced that neither age nor circumstance needs to deprive us of energy and vitality. We are at last awakening to the close relationship between religion and health. We are beginning to comprehend a basic truth hitherto neglected, that our physical condition, and our emotional life is profoundly regulated by our thought life.”
This book teaches that the Christian faith offers a peace of mind that transcends human understanding. Not only can we have a mind that has peace during trying times in life, but we can have a mind and body that has energy! I am learning that a mind that is negative and worrisome produces a body that lacks energy- and vise versa. I highly suggest the book.
