The will should never be used upon any person or thing external to you, and it should never be used upon your own body. The sole legitimate use of the will is in determining to what you shall give your attention, and what you shall think about the things to which your attention is given. All belief begins in the will to believe. You cannot always and instantly believe what you will to believe; but you can always will to believe what you want to believe. You want to believe truth about health, and you can will to do so. The statements you have been reading in this book are the truth about health, and you can will to believe them; this must be your first step toward getting well. These are the statements you must will to believe:-- _That there is a Thinking Substance from which all things are made, and that man receives the Principle of Health, which is his life, from this Substance._ _That man himself is Thinking Substance; a mind-body, permeating a physical body, and that as man's thoughts are, so will the functioning of his physical body be._ _That if man will think only thoughts of perfect health, he must and will cause the internal and involuntary functioning of his body to be the functioning of health, provided that his external and voluntary functioning and attitude are in accordance with his thoughts._ When you will to believe these statements, you must also begin to act upon them. You cannot long retain a belief unless you act upon it; you cannot increase a belief until it becomes faith unless you act upon it; and you certainly cannot expect to reap benefits in any way from a belief so long as you act as if the opposite were true. You cannot long have faith in health if you continue to act like a sick person. If you continue to act like a sick person, you cannot help continuing to think of yourself as a sick person; and if you continue to think of yourself as a sick person, you will continue to be a sick person.
