been a scaffold to me.
My friends: There are so many who have encouraged me
and spoken words of wisdom and prophecy over my
life, and who contributed to this book in ways they
perhaps don’t even realize. Mentioning all of you would
fill pages, but you know who you are, and I appreciate
and love you all. In fact, it was hard to choose who
not
to ask to do endorsements because I wanted all of you
in my book.

Switch On Your Brain with Hope
Main Scripture: Faith is the substance of things
hoped for, the evidence of things not seen. He-
brews 11:1
Linked Science Concept: Thoughts are real, physical
things that occupy mental real estate. Moment by
moment, every day, you are changing the structure
of your brain through your thinking. When we hope,
it is an activity of the mind that changes the struc-
ture of our brain in a positive and normal direction.
It was only a few decades ago that scientists—including
those who trained me—considered the brain to be a fixed
and hardwired machine. This view saw the damaged brain
as incurable. They believed brain damage was hopeless and
untreatable, whether the effects were from stroke, cardio-
vascular event, traumatic brain injury, learning disabilities,
traumas, PTSD, OCD, depression, anxiety—even aging. All of
these causes and conditions were seen as largely irreversible.

Because this was the presiding view of the brain, I was
trained back in the ’80s to teach my patients
compensation
,
not
restoration
of function. I was trained in the conventional
wisdom of the time that said brain normality was an impos-
sibility for those with mental limitations or brain damage of
any kind. Being a student of the Bible, however, I was deeply
familiar with and constantly comforted by Romans 12:2: “Do
not conform to the pattern of this world, but be transformed
by the renewing of your mind” (NIV). I knew this famous and
fabulous “renewing of the mind” passage was a truth I needed
to apply to my patients’ care to help them overcome their defi-
cits. So my relentless search of this truth as a scientist began.
I was struck by how my patients, using the therapeutic
techniques I was developing from my research, belied the
negative picture conventional science presented of the human
brain at that time. These results confirmed that the brain,
far from being fixed in toxicity, can change even in the most
challenging neurological situations.
I was in awe of what each patient displayed in terms of what
you
can do when you set your mind to it
. Each new scientific
study in this direction confirmed what I knew intuitively to
be true: We are not victims of our biology or circumstances.
How we react to the events and circumstances of life can have
an enormous impact on our mental and even physical health.
As we think, we change the physical nature of our brain.
As we consciously direct our thinking, we can wire out toxic
patterns of thinking and replace them with healthy thoughts.
New thought networks grow. We increase our intelligence
and bring healing to our brains, minds, and physical bodies.
It all starts in the realm of the mind, with our ability to
think and choose—the most powerful thing in the universe
after God, and indeed, fashioned after God.

Toxic Memory: Adapted Graphic Sketch
It is with our phenomenal minds that we understand the
truths set down in our spirits. It is with our minds that we
wire these truths into the brain, which is part of the body.
It is with our minds that we choose to develop the spiritual
part of who we are and “Therefore put away all filthiness and
rampant wickedness and receive with meekness the implanted
21

word, which is able to save your souls” (James 1:21 ESV).
It is with our minds that we reject or believe the lies of the
Enemy, the Prince of Lies. It is with our minds that we change
the physical reality of the brain to reflect our choices. It is
with our minds that we decide to follow God’s rules and live
in peace despite what is going on around us. It is with our
minds that we choose to follow the lies of Satan and spiral
into mental, physical, and spiritual disarray.
Thought changes the structure of matter. God said, “Let
there be light” (Gen. 1:3), and his words produced the phys-
ical earth. And science, which, again, is just catching up with
the Word of God, is confirming this reality in a tangible and
thought-provoking way with eminently clear accounts arising
from the burgeoning field of neuroplasticity research.
Neuroplasticity by definition means the brain is malleable
and adaptable, changing moment by moment of every day.
Scientists are finally beginning to see the brain as having
renew able characteristics (as in Rom. 12:2); it is no longer
viewed as a machine that is hardwired early in life, unable to
adapt, and wearing out with age. With example after fasci-
nating example, exceptional scientists talk about and dem-
onstrate—using brain-imaging techniques and the evidence
of behavioral changes—how people can change their brains
with their minds. We can see and measure the activity of the
mind through the firing of neurons. We can even predict the
seeming elusiveness of the main functions of the mind—that
of thinking and choosing—through quantum mechanics.
I continue to find myself moving in a world of engrossing
truths, and my spirit leaps inside of me. The fact that the
brain is plastic and can actually be changed by the mind gives
tangible hope to everyone, no matter what the circumstance.
I have been privileged to work with and see:

• autistic children cope in academic and social environ ments
• senior citizens sharpen their memories to the point that
in their eighties they change careers and obtain degrees
• young men and women who grew up in abject poverty
and a lifestyle of selling and taking drugs do a complete
about-face in their lives, go back to school, and become
leaders in their communities
• car accident victims who had been written off by neu-
rologists as “vegetables” retrain their brains to the point
that they complete their schooling up to a tertiary level
and go on to become successful, contributing citizens
• students labeled as learning disabled with years of ther-
apy and no hope left master learning and achieve grades
they and their parents only dreamed of
• schools in some of the worst third-world areas in Af-
rica, in which students could not pass to the next level,
become schools on the minister of education’s “most
improved” list
• children with dyslexia learn to read and write and even
help their parents study for exams successfully
• suicidal and emotionally traumatized minds set free
• entire schools improve grades across core subjects
And the list goes on.
Science is hovering on a precipice as we recognize the re-
sponsibility and impact of our thinking and the resultant
choices we make, which have ramifications right down to the
ways in which the genes of our bodies express themselves.
Deuteronomy 30:19 is becoming a reality in the world we
live in today as we begin to see the effects of choice in the
brain and body: “I set before you life and death, blessing
23
_Leaf_SwitchOnBrain_LS_mw.indd 23

and cursing; choose life so that you and your descendants
may live.”
How we think not only affects our own spirit, soul, and
body but also people around us. Science and Scripture both
show how the results of our decisions pass through the sperm
and ova to the next four generations, profoundly affecting
their choices and lifestyles. The science of epigenetics (the
signals, including our thoughts, that affect the activity of
our genes) explains how this plays out. This reminds me of
the Scripture, “he punishes the children and their children
for the sin of the parents to the third and fourth generation”
(Exod. 34:7 NIV).
That the brain is plastic and can be changed moment-by-
moment by how we direct our thinking—in other words, the
choices we make—is a top idea on the bestseller lists, and it
actually is the key to switching on our brains. Add to this the
fact that every morning when you wake up, new baby nerve
cells have been born while you were sleeping that are there
at your disposal to be used in tearing down toxic thoughts
and rebuilding healthy thoughts. The birth of these new baby
nerve cells is called neurogenesis, which brings to mind, “The
Lord’s mercies . . . are new every morning” (Lam. 3:23).
What a remarkable and hopeful portrait of the endless
adaptivity of the human brain God has given us.
This book is divided into two parts, with the overall goal
of showing you how to switch on your brain. Part 1 uncovers
the keys to doing so. In part 2 you will see how all these keys
work together in my 5-Step Switch On Your Brain Learning
Process during my 21-Day Brain Detox Plan. Here I will lead
you through a process of switching on your brain to achieve
peak happiness, thinking, and health.
Here are some of the key points in this book:

• Your mind is the most powerful thing in the universe
after God.
• Free will and choice are real, spiritual, and scientific facts
(Deut. 30:19).
• Your mind (soul) has one foot in the door of the spirit
and one foot in the door of the body; you can change
your brain with your mind and essentially renew your
mind (Rom. 12:2).
• You can develop your spirit through choices you make
in your mind to be led by the Holy Spirit (Gal. 2:20).
• Your body is not in control of your mind—your mind is
in control of your body, and your mind is stronger than
your body. Mind certainly is
over
matter.
• You are not a victim of your biology.
• You cannot control the events and circumstances of life,
but you can control your reaction to those events and
circumstances (Matt. 7:13–14; Gal. 6:7–8).
• When you think, you build thoughts, and these become
physical substances in your brain. “As he thinks in his
