load also increased three times faster, and their stress levels
were higher, with damaging amounts of cortisol flowing. Dr.
Ironson summarizes her research by saying, “If you believe
God loves you, it’s an enormously protective factor, even
more protective than scoring low for depression or high for
optimism. A view of a benevolent God is protective, but
scoring high on the
personalized
statement ‘God loves
me
’
is even stronger.”17
As you can imagine, the implications of this research are
enormous, from how we present ourselves to others to how we

help others and ourselves manage illness. Our choices have an
impact. Our choices become
physiology
, and what we believe
as well as what we believe about ourselves alters the facts.
We are not victims of our biology. We are co-creators of
our destiny alongside God. God leads, but we have to choose
to let God lead. We have been designed to create thoughts,
and from these we live out our lives (Prov. 23:7).
Hebrews 11:1 says, “Faith is the substance of things hoped
for, the evidence of things not seen.” Whatever you believe in
and hope for becomes substance on a physical level, and you
act upon this. This process can move in either direction—
negative or positive.
In the next chapter we look more in depth at the impact
of our choices and how to eliminate toxic choices.
1. You are not a victim. You can control your reactions.
You do have a choice.
2. Free will is not an illusion. Thinking it is an illusion is
dangerous thinking, and it basically says that we are not
responsible for our actions, thus providing an excuse
to do whatever we want to do, with no consequences.
3. Our free will influences our thinking, which produces
our state of mind. This is so important to human be-
havior and potential that I have dedicated my life to
understanding the process of thought and how we can
choose to think the way God wants us to think. Far from
explaining away free will, the neuroscientific evidence
actually explains how free will works.
4. What we say and do is based on what we have already
built into our minds. We evaluate this information and

make our choices based on this information. Then we
choose to build a new thought, and this is what drives
what we say and do.
5. Choice has mental
real estate
around the front of the
brain. Certain areas light up when we think and choose.
6. One of the most exciting features of frontal lobes is
how they enable us in a sense to stand outside ourselves
and observe our own thinking.
7. We have what I like to call “multiple-perspective ad-
vantage”—MPA for short. Our unique, multifaceted
nature, made in God’s image, allows us to see things
from many different angles or perspectives.
8. All this thinking activity is real, and it can be seen on
various types of brain imaging.
9. This
thinking
creates signals that unzip the DNA, which
then expresses genes making proteins.
10. We have a switch gene called the “creb gene” that we
choose to switch on with our thoughts.
11. Our genetic makeup fluctuates by the minute based on
what we are thinking and choosing.
12. A time is coming when medical practitioners will in-
clude admonitions like Philippians 4:8 and Romans
12:2 on their prescription pads. Part 2 of this book is
designed to help you apply God’s prescription.
13. From the gene myth to the truth: We are not victims of
our biology; we control our biology.

Your Choices
Change Your Brain
Main Scripture: Do not conform to the pattern of
this world, but be transformed by the renewing of
your mind. Then you will be able to test and approve
what God’s will is—his good, pleasing and perfect
will. Romans 12:2 NIV
Linked Science Concept: Through our thoughts we
can be our own micro surgeons as we make choices
that will change the circuits in our brains. We are
designed to do our own brain surgery and rewire
our brains by thinking and by choosing to renew
our minds.
Our choices—the natural consequences of our thoughts
and imagination—get “under the skin” of our DNA
and can turn certain genes on and off, changing
the structure of the neurons in our brains. So our thoughts,
55

imagination, and choices can change the structure and function
of our brains on every level: molecular, genetic, epigenetic,
cellular, structural, neurochemical, electromagnetic, and even
subatomic. Through our thoughts, we can be our own brain
surgeons as we make choices that change the circuits in our
brains. We are designed to do our own brain surgery.
This scientific power of our mind to change the brain is
called
epigenetics
and spiritually it is as a man thinks, so is he
(Prov. 23:7). The way the brain changes as a result of mental
activity is scientifically called
neuroplasticity
. And spiritually,
it is the renewing of the mind (Rom. 12:2).
In chapter 2, I introduced you to the science of epigenetics,
which is tangible, scientific proof of how important our choices
are; they bring life or death, blessing or cursing; and they reach
beyond us to influence the next generations (Deut. 30:19). This is
because choices become signals that change our brain and body,
so these changes are not dictated by our genes. Our thinking and
subsequent choices become the signal switches for our genes.
What’s incredible is that genes are dormant until switched on
by a signal; they have potential, but they have to be activated to
release that potential. They have to be unzipped. (See chap. 2.)
Epigenetics Is an Ancient Science and Spiritual Truth
Epigenetics is referred to as a new science, but actually it is
an ancient science that we find throughout the Bible. At its
most basic level, epigenetics is the fact that your thoughts
and choices impact your physical brain and body, your men-
tal health, and your spiritual development (Deut. 30:19; Ps.
34:11–16; Prov. 3:7–8). And these choices will impact not
only your
own
spirit, soul, and body but also the people with
whom you have relationships. In fact, it goes even deeper; your
56

Your Choices Change Your Brain
choices might impact the generations that follow: “For the
sin of the parents to the third and fourth generation” (Exod.
34:7 NIV; see also Exod. 20:1–6; Num. 14:8; Deut. 5:9).
The decisions you make today become part of the thought
networks in your brain. The two copies of the chromosome that
you carry in each of your cells contain the entire set of genetic
material necessary to make you. An interesting point: A cell
in your brain and a cell in your kidney contain the exact same
DNA. And while in utero (in the womb), the nascent (emerging,
developing) cells differentiate into either a brain cell or a kidney
cell
only
when crucial epigenetic processes turn the right genes
on or off. So God has designed perfectly timed epigenetic signals
to switch on in the womb as the baby is developing. “Before I
formed you in the womb I knew you” (Jer. 1:5).
Our Thoughts Can Impact the Next Four Generations
Science has demonstrated how the thought networks pass
through the sperm and the ova via DNA to the next four
generations.
One of the first studies showing that an epigenetic signal
can affect genetic expression was done with mice that had
the agouti gene, which caused them to be fat, have a yellow
coat, and have an increased incidence of cancer and diabe-
tes. When the agouti gene occurs in humans, it is related to
obesity and type 2 diabetes. In the experiment, just before
conception, the agouti mother mice were fed a nutritional
chemical called a methyl group in the form of a B vitamin.
This acts as a methyl donor, which suppresses the gene ex-
pression, with the result that the offspring of this group did
not get fat or yellow. So an external signal—the nutritional
methyl—changed the generational pattern.1

This landmark study fostered a host of studies—including
some done on humans—that showed that not only does food
change generational patterns, but so does thinking.2 In 2003
the Human Epigenome project was launched, which showed
that epigenetics had moved from being a sideshow back in
the 1970s to what is now a main show in the biological arena,
putting genetics in a more proportional place.3
Scientific Mysteries
Epigenetics explains certain scientific mysteries that traditional
genetics never could—for example, why one member of a pair
of identical twins develops asthma but the other does not.
They have the same genome, so they should respond the same
way, but their individual perception of the world (what I term
the “I-factor”) as well as their ability to choose means they
think and react differently, which alters their genetic expres-
sion. Although their genes are the same, their
patterns of ex-
pression can be tweaked
through the signal. And this signal is
mainly affected by our reaction to the events and circumstances
of life. This is profound and the implications are enormous:
the way we react—our thinking and choosing—becomes the
signal that activates or deactivates the generational issues in
our lives.
The Good, the Bad, and the Ugly
Taken collectively, the studies on epigenetics show us that the
good, the bad, and the ugly do come down through the genera-
tions, but your mind is the signal—the epigenetic factor—that
switches these genes on or off. Therefore, you are not destined
to live out the negative patterns of your forebearers—you can
58
_Leaf_SwitchOnBrain_LS_mw.indd 58

instead make a life choice to overcome by tweaking their pat-
terns of expression. Part 2 of this book will show you how.
Taking this further, the Scriptures that tell us the sins of the
parents will reach to the third and fourth generation (Exod.
20:5; 34:7; Num. 14:18) seem to imply that we are responsible
for the unconfessed sins of our great-great-grandparents. But
we can breathe a sigh of relief when we read Deuteronomy
24:16 and Ezekiel 18:19–20, which explain that we are each
responsible for our own sins and not those of our ancestors.
I know this seems confusing, because the Scriptures say that,
on the one hand, a parent’s iniquity will be visited on the chil-
dren, but, on the other hand, we are only responsible for our own
sins. Here is how it works: Epigenetic changes represent a bio-
logical response to an environmental signal. That response can
be inherited through the generations via the epigenetic marks.
But if you remove the signal, the epigenetic marks will fade.
By the same token, if you choose to add a signal—for ex-
ample, saying something like, “My mother had depression
and that’s why I have depression, and now my daughter is
suffering from depression”—then the epigenetic marks are
activated. The thinking and speaking out the problem serve
as the signal that makes it a reality. I have seen this over the
years in my private practice and in my seminars, and even
in my own life and the lives of my family and friends, time
and time again. If we don’t wake up to these truths, they
will catch us when we are not looking, and before you know
it you will be living a life you didn’t plan on living. If this is
you, here is the good news: You
can
change.
Predisposition versus Destiny
Herein lies the key: The sins of parents create a
predisposi-
tion
, not a
destiny
. You are not responsible for something you
59

are predisposed to because of ancestral decisions. You are
responsible, however, to be aware of predispositions, evaluate
them, and choose to eliminate them.
The epigenetic marks in our genes that may predispose
us to smoke, eat too much of the wrong foods, be negative,
or worry can change. This can cause, for example, the genes
