“A good person out of the good treasure of their heart brings forth good, but an evil person out of the evil treasure of their heart brings forth evil. For out of the abundance of the heart their mouth speaks” (Luke 6:45).
Have you ever wondered why God says in Scripture that His children are to write His Word on their hearts, as in Prov 3:3 and 7:3, where it says that we are to write His Word on the tablet of our hearts. What does a “tablet” make you think of? Certainly, it is a place to record something important, so that you can remember it later – this is true whether it is a paper tablet or a modern-day hand-held tablet computer, iPad or other eReader device.
So, we can think of our hearts as a place to keep God’s word safe and secure, as David said in Ps 119:11, that he would hide God’s Word in his heart that he might not sin. Another example of how important it is to keep the Word in our hearts is in Deut 30:14 – “But the word is very near you, in your mouth and in your heart, that you may do it.” This is why Ezekiel prophesied that God would take the “hearts of stone out of our flesh and give us hearts of flesh”. In other words, God softens and even circumcises (Jer 4:4) our hearts so He can prepare them to receive His Word.
Paul said in 2 Cor 3:3 that the believers in Corinth were like letters “written not with ink but by the Spirit of the living God, not on tablets of stone but on tablets of flesh, that is, of the heart.” Once again, we see how God has prepared the hearts of His people, in this case so that they can go forth to the world and be living testimonies (letters) sharing the Gospel of the Kingdom with all people.
What then is so special about our hearts, that we need to always keep them pure and filled with God’s Word (as in Prov 4:21 where it says we are to keep His Word “in the midst of our hearts”)? Did God design our hearts in a special way so that they can store and remember His Word, allowing us to keep it in the forefront of our minds whenever a situation arises in our lives that requires us to have His word on our lips and ready to speak.
Fortunately, living in this age of scientific research and technology, we now have confirmation from neuro-imaging that we actually have brain cells (neurons) located around our heart, which function in conjunction with the neurons in the head, and perform unique tasks within our body’s thought processes. From neurological research, we now know that “the heart-brain is composed of about 40,000 neurons that can sense, feel, learn and remember” (Science of the Heart: Exploring the Role of the Human Heart in Human Performance: http://www.heartmath.org/research/science-of-the-heart/introduction.html).
Brain researchers have also learned that the neurons in the heart-brain have both short- and long-term memory, and the signals they send to the head-brain can affect our perception and emotions. A number of scientists who have studied the heart-brain’s behavior and interaction with the head-brain have concluded that our heart-brain actually acts as our conscience, helping our head-brain make the right decisions and take the right actions. So we can truly say that hiding God’s word in our hearts (Ps 119:11) does actually keep us from sinning and keeping His word in the midst of our hearts brings us life and good health (Prov 4:22)!
Finally, dear brothers and sisters, “You shall love the Lord your God with all your heart and with all your soul and with all your might. And these words that I command you today shall be on your heart. Deut 6:5-6
