Popular sayings about the intuitive and intelligent aspects of the human heart like “follow your heart” have long been considered to be strictly metaphorical, but scientific studies show that the heart is more than just a mass of muscle cells pumping blood throughout the body.
The heart is in constant communication with the body and brain using neurons, biochemicals, blood pressure waves and electricity, and has its own independent nervous system, and therefore, the heart has a much greater impact on information processing, perceptions, emotions and health than was ever acknowledged in the past.
In the early 1990s, the “heart-brain” concept was introduced by Dr. J. Andrew Amour and became a pivotal part of medical science’s newest discipline — neurocardiology.
Amour’s research looked at the heart’s complex network of neurotransmitters, support cells and proteins, and determined it was a nervous system that was similar enough to the brain itself to qualify as a “little brain.”

Turning now to the Bible, Strong’s Concordance lists over 700 references to “heart” in the Old and New Testaments. From the New Testament (KJV), here are just six examples which speak of the heart having properties we normally ascribe to the brain:
“Out of the heart the mouth speaketh….” Matthew 12:34
“and should understand with their heart….” Mt 13:15
“evil servant shall say in his heart…” Mt 24:48
“the thought of their heart….” Luke 9:47
“thine heart to lie to the Holy Ghost…..” Acts 5:3
“believest with all thy heart….” Acts 8:37.
