You Become What You Think: How Your Thoughts Shape Your Brain, Body, and Soul

Show Notes
Transcript

In this episode of Chasing Eden, we explore a powerful truth that Scripture has proclaimed for centuries, and neuroscience is now confirming: the thoughts you repeatedly entertain shape your brain, body, and spiritual life. Far from shallow positivity, this conversation examines disciplined, truth-anchored thinking—how patterns of hope, gratitude, and faith literally rewire neural pathways, influence stress hormones, strengthen immunity, and cultivate emotional resilience. Using insights from leading brain and health experts, this episode reveals that thoughts are not abstract ideas, but biological events with real consequences.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

00:00:21.359 --> 00:00:26.920
Welcome back to the Chasing Eden podcast, where we rediscover

2
00:00:27.320 --> 00:00:34.320
your body's divine design and explore how faith, science, and

3
00:00:34.560 --> 00:00:40.039
wisdom come together for whole person health. I'm your host,

4
00:00:40.320 --> 00:00:43.439
Carolyn Thompson, and thank you for joining me today for

5
00:00:43.560 --> 00:00:49.000
a truly compelling and thought provoking conversation. In this episode,

6
00:00:49.320 --> 00:00:53.640
we're diving into a powerful truth that scripture has taught

7
00:00:53.640 --> 00:00:58.880
for centuries, and neuroscience is only catching up to how

8
00:00:58.920 --> 00:01:02.439
the thoughts we allow to take root shape our brain,

9
00:01:03.000 --> 00:01:08.400
our body, and even our spiritual life. Today's topic is

10
00:01:08.519 --> 00:01:14.000
one that quietly influences every decision we make, often without

11
00:01:14.079 --> 00:01:20.400
us even realizing it. You become what you think. There

12
00:01:20.439 --> 00:01:24.680
is something shaping your life, long before your schedule fills up,

13
00:01:25.400 --> 00:01:30.200
long before your body feels tired, long before words ever

14
00:01:30.359 --> 00:01:36.879
leave your mouth. It's shaping how you interpret hardship, how

15
00:01:36.920 --> 00:01:43.159
your body responds to stress, how your faith holds or

16
00:01:43.359 --> 00:01:53.319
fractures under pressure. It is quiet, constant, persistent. It's your thoughts.

17
00:01:53.359 --> 00:01:58.439
Every human being lives inside a stream of inner dialogue,

18
00:01:58.560 --> 00:02:01.799
and most of us never never pause long enough to

19
00:02:02.000 --> 00:02:08.120
ask the most important question. Is this inner voice building

20
00:02:08.240 --> 00:02:15.680
life or slowly dismantling it? For centuries, Scripture warned us

21
00:02:16.000 --> 00:02:21.719
that the mind is not neutral territory. Proverbs twenty three

22
00:02:21.800 --> 00:02:25.919
seven says, as a man thinks in his heart, so

23
00:02:26.520 --> 00:02:32.240
is he? That verse doesn't say as a man feels,

24
00:02:32.680 --> 00:02:36.360
It doesn't say as a man hopes, It says as

25
00:02:36.400 --> 00:02:44.199
he thinks. And now, almost reluctantly, modern neuroscience has arrived

26
00:02:44.280 --> 00:02:50.280
at the same conclusion. Brain imaging now shows what pastors,

27
00:02:50.560 --> 00:02:56.360
prophets and wisdom writers already knew. Thoughts are not imaginary.

28
00:02:57.120 --> 00:03:02.879
They are biological events. They change neural wiring, they alter

29
00:03:03.120 --> 00:03:09.960
hormone release, they influence immune response. They shape behavior long

30
00:03:10.080 --> 00:03:16.639
before behavior becomes visible. Welcome to Chasing Eden, where we

31
00:03:16.840 --> 00:03:21.159
explore God's original design for the body, mind, and soul,

32
00:03:22.039 --> 00:03:27.840
and how reclaiming that design restores clarity, peace, and resilience.

33
00:03:31.840 --> 00:03:36.360
So today's episode is also about being disciplined and having

34
00:03:36.520 --> 00:03:42.280
truth anchored thinking the kind of thinking Scripture commands, And

35
00:03:42.680 --> 00:03:46.199
like I said before, science now confirms how the brain

36
00:03:46.360 --> 00:03:51.639
reshapes itself. We're going to hear insights from doctor Daniel Aman,

37
00:03:52.120 --> 00:03:57.639
who has spent decades proving through spect scans that negative

38
00:03:57.719 --> 00:04:04.080
thinking physically suppresses brain function. From doctor Carolyn Leaf, who

39
00:04:04.120 --> 00:04:09.319
demonstrates that thoughts are measurable structural forces in the brain

40
00:04:09.400 --> 00:04:14.719
and body. Also from doctor Barbara O'Neill and doctor Josh Ax,

41
00:04:15.120 --> 00:04:22.759
who connect mindset to inflammation, digestion, and healing. Will also

42
00:04:22.839 --> 00:04:27.319
ground this biblical clarity from John MacArthur, modern communication wisdom

43
00:04:27.360 --> 00:04:31.600
from Jefferson Fisher, and a quiet but powerful story from

44
00:04:31.639 --> 00:04:35.600
Fred Rogers, a man who modeled positive thinking through action,

45
00:04:36.000 --> 00:04:41.079
not denial. And above all, we're gonna let scripture speak

46
00:04:41.160 --> 00:04:44.959
because long before science caught up, God already told us

47
00:04:45.360 --> 00:04:51.000
where transformation begins. Romans twelve to two says, be transformed

48
00:04:51.079 --> 00:04:55.439
by the renewing of your mind. Let's begin where every

49
00:04:55.639 --> 00:05:02.800
transformation begins. Thoughts lead footprints in the brain. For much

50
00:05:02.800 --> 00:05:08.800
of modern history, we treated thoughts as harmless passengers, background noise,

51
00:05:08.879 --> 00:05:13.560
riding along while the real work happened elsewhere. But brain

52
00:05:13.680 --> 00:05:19.759
imaging shattered that illusion. On the Diary of a CEO podcast,

53
00:05:20.120 --> 00:05:24.000
doctor Daniel Aman explained that when his team began scanning

54
00:05:24.040 --> 00:05:28.720
brains using the spect technology, patterns emerged that could not

55
00:05:28.839 --> 00:05:33.160
be ignored. He says this quote, when you look at

56
00:05:33.160 --> 00:05:37.319
the brain, you can see the effects of people's thought patterns.

57
00:05:37.959 --> 00:05:43.639
Negative thinking decreases activity in the frontal lobes. Positive hopeful

58
00:05:43.680 --> 00:05:49.480
thinking increases it unquote. The frontal lobes are where judgment lives,

59
00:05:49.959 --> 00:05:56.519
self control, empathy, future planning, and moral reasoning. When those

60
00:05:56.759 --> 00:06:01.959
areas go under active, people don't simply feel discouraged, they

61
00:06:02.000 --> 00:06:07.680
lose capacity. Doctor Amon often says, quote, your brain is

62
00:06:07.759 --> 00:06:11.240
involved in everything you do. If you hurt your brain,

63
00:06:11.759 --> 00:06:19.600
you hurt your life unquote. Chronic negative thinking, fear, resentment,

64
00:06:20.160 --> 00:06:26.360
hopelessness reduces blood flow to these regions. Over time, the

65
00:06:26.439 --> 00:06:30.920
brain learns this pattern and defaults to it. This is

66
00:06:31.319 --> 00:06:37.160
neuroplasticity in action. Doctor Carolyn Leaf expands on this in

67
00:06:37.279 --> 00:06:43.439
powerful terms. Quote thoughts are real. They occupy mental real estate.

68
00:06:43.800 --> 00:06:46.879
They build networks in the brain that become easier to

69
00:06:47.079 --> 00:06:51.439
access the more you use them unquote. She explains that

70
00:06:51.560 --> 00:06:57.240
repeated thought patterns create what she calls quote thought trees unquote,

71
00:06:57.399 --> 00:07:04.399
physical neural structures that stronger with repetition. Scripture decides to

72
00:07:04.720 --> 00:07:09.399
describe this long before neuroscience. In Sewod Corinthians ten to five.

73
00:07:09.399 --> 00:07:13.160
It says, take every thought captive to the obedience of

74
00:07:13.279 --> 00:07:19.120
Christ unquote. Why capture a thought unless it can run

75
00:07:19.240 --> 00:07:26.199
somewhere dangerous because unchecked thoughts do exactly that. Doctor Amon

76
00:07:26.360 --> 00:07:30.720
often reminds patients, quote, if you think you're broken, your

77
00:07:30.720 --> 00:07:34.439
brain will act broken. If you think you're healing, your

78
00:07:34.439 --> 00:07:39.560
brain will cooperate with healing unquote. That isn't positive thinking

79
00:07:39.600 --> 00:07:46.879
as fantasy, it's positive thinking as neural instruction. After the break,

80
00:07:47.240 --> 00:07:51.079
we'll explore how negative thinking doesn't just damage the brain.

81
00:07:51.800 --> 00:08:00.519
It suppresses immunity, digestion, and the body's ability to heal.

82
00:08:21.240 --> 00:08:26.920
Long before labs and microscopes, ancient healers noticed something modern

83
00:08:27.000 --> 00:08:35.120
medicine is now rediscovering. The body obeys the mind. Doctor O'Neill.

84
00:08:35.600 --> 00:08:40.840
Barbara O'Neill states this plainly, quote, the body responds to

85
00:08:41.000 --> 00:08:46.399
thought faster than it responds to medication. Fear titans, hope

86
00:08:46.639 --> 00:08:53.440
opens unquote. Chronic negative thinking activates the sympathetic nervous system,

87
00:08:53.919 --> 00:08:58.039
the fight or flight response. This response is designed for

88
00:08:58.159 --> 00:09:03.720
short bursts of danger, not long term living. When it

89
00:09:03.799 --> 00:09:11.600
stays activated, digestion slows, immune response weakens, inflammation rises, and

90
00:09:11.720 --> 00:09:17.440
sleep deteriorates. Doctor Carolyn Leaf explains it like this quote,

91
00:09:18.200 --> 00:09:25.320
Toxic thoughts create toxic stress. Toxic stress damages cells tissues

92
00:09:25.720 --> 00:09:32.679
and systems throughout the body. Unquote. Research confirms this. Studies

93
00:09:32.720 --> 00:09:40.759
show pessimistic thinking correlates with increased inflammatory markers, higher corticol levels,

94
00:09:41.159 --> 00:09:47.320
and reduced immune cell activity. Meanwhile, hopeful and grateful thinking

95
00:09:47.799 --> 00:09:54.200
improves heart rate variability, immune resilience, and even wound healing.

96
00:09:55.000 --> 00:09:58.960
The Bible says in Proverbs seventeen twenty two, quote, A

97
00:09:59.159 --> 00:10:03.639
joyful heart is good medicine, but a crushed spirit dries

98
00:10:03.759 --> 00:10:09.639
up the bones. Unquote. Doctor Josh Acts connects this directly

99
00:10:09.679 --> 00:10:15.120
to modern health crisis. He says this quote, Chronic stress

100
00:10:15.240 --> 00:10:18.320
and negative thinking are some of the biggest drivers of

101
00:10:18.480 --> 00:10:25.679
gut dysfunction, hormone imbalance, and autoimmune disease. Unquote. Your thoughts

102
00:10:25.759 --> 00:10:29.679
are not floating above your body, they are instructing it.

103
00:10:31.879 --> 00:10:36.720
When we return, we'll draw a critical distinction biblical renewal

104
00:10:36.879 --> 00:10:59.879
of the mind versus cultural positivity. This is where clarity matters.

105
00:11:00.519 --> 00:11:07.039
Scripture does not teach blind optimism, it teaches truth aligned thinking.

106
00:11:08.360 --> 00:11:12.440
John MacArthur is clear, quote the Christian mind is not

107
00:11:12.639 --> 00:11:17.279
shaped by emotions or circumstances, but by the truth of

108
00:11:17.440 --> 00:11:23.559
God's word. Paul commands believers in Philippian's fore eight. Whatever

109
00:11:23.759 --> 00:11:28.799
is true, whatever is noble, whatever is right, think on

110
00:11:29.080 --> 00:11:37.559
these things. That command implies effort, choice, discipline. Podcaster Jefferson

111
00:11:37.559 --> 00:11:41.799
Fisher explains this in modern language, quote, your internal dialog

112
00:11:42.240 --> 00:11:48.080
becomes your external behavior, especially under pressure. This is why

113
00:11:48.200 --> 00:11:53.240
Fred Rogers mattered so deeply after tragic events. He didn't

114
00:11:53.279 --> 00:11:59.440
deny pain. He redirected attention. He said things like this quote,

115
00:12:00.159 --> 00:12:03.279
look for the helpers. You will always find people who

116
00:12:03.360 --> 00:12:09.519
are helping. That wasn't denying, That was trained perception. This

117
00:12:09.679 --> 00:12:14.360
is something his mother told him when he demonstrated fear

118
00:12:14.879 --> 00:12:17.879
during some type of tragic thing that was going on

119
00:12:18.000 --> 00:12:23.240
at the moment. Scripture also echoes it. Romans twelve twenty

120
00:12:23.240 --> 00:12:27.120
one says, do not be overcome by evil, but overcome

121
00:12:27.240 --> 00:12:32.679
evil with good. Positive thinking in the Biblical sense, is

122
00:12:32.799 --> 00:12:40.360
resistance against despair. The coming years will demand mental resilience,

123
00:12:40.720 --> 00:12:46.919
information overload, fear based headlines, and cultural anxiety. This makes

124
00:12:46.960 --> 00:12:51.679
renewing the mind not optional but essential. Isaiah twenty six

125
00:12:51.720 --> 00:12:54.639
to three says you will keep him in perfect peace.

126
00:12:54.879 --> 00:13:00.000
Whose mind stayed on you. Doctor Amen often says, quote,

127
00:13:00.519 --> 00:13:03.480
you can't change your life until you change your brain.

128
00:13:04.080 --> 00:13:08.919
And you can't change your brain without changing how you think. Unquote.

129
00:13:09.120 --> 00:13:14.120
This is stewardship. Your thoughts are seeds, Your mind is soil.

130
00:13:15.200 --> 00:13:23.440
What you plant today determines what grows tomorrow. Your mind

131
00:13:23.559 --> 00:13:27.159
is not a battlefield you're losing. It's a garden waiting

132
00:13:27.240 --> 00:13:32.120
to be tended. Every thought you water grows. Every lie

133
00:13:32.720 --> 00:13:39.320
you uproot weakens. Every truth you plant bears fruit. As

134
00:13:39.360 --> 00:13:42.919
we step into twenty twenty six, don't merely resolve to

135
00:13:43.000 --> 00:13:47.879
do better. Resolve to think better, not by denying reality,

136
00:13:48.559 --> 00:13:52.399
but by aligning your mind with truth. Colossians three to

137
00:13:52.480 --> 00:13:58.240
two says, set your mind on things above and just

138
00:13:58.240 --> 00:14:03.919
a reminder Philippians for a Finally, brothers and sisters, whatever

139
00:14:04.080 --> 00:14:09.919
is true, whatever is noble, whatever is right, whatever is pure,

140
00:14:10.720 --> 00:14:16.360
whatever is lovely, whatever is admirable, if anything is excellent

141
00:14:16.679 --> 00:14:22.919
or praiseworthy, think about such things. This is how Eden

142
00:14:23.039 --> 00:14:28.759
begins again in the mind God designed. Thank you for
