How many cliches have you heard regarding the heart? Here are a few:
"Trust Jesus with your heart."
"Listen with your heart, and not your head."
"You have to follow your heart."
"Eighteen inches—the distance from your head to your heart—can mean eternity with Christ or an eternity without Him."
These may sound good, but they are not only unbiblical, they are unscientific. When people talk about the "heart," they are not talking about the organ within your chest. This organ does not think or feel. It only pumps blood throughout your entire body. The "heart" they are referring to is the center of man, the core of his being. Your mind is where thoughts, feelings, emotions, and attraction take place.
Your heart organ cannot trust. Your heart organ cannot tell you things, and does not tell you things differently than your head. The idea that you need to "Listen to your heart, and not your head" is utterly ridiculous. Clichés like these need to die. People need to spend a little more time thinking about what it is they want to say, and then do so in a more accurate manner.
I believe the distinction Scripture gives this issue is knowledge ("knowledge puffs up") versus action. You have to act out what you believe. It has to become real to you. A bunch of information does not do a thing for you. But if you believe it and act upon it, it says a lot. I believe Scripture would also give it the distinction of knowledge versus faith. Knowledge can help faith, but knowledge without faith is pretty damning.
The heart cannot think, feel, trust, or anything else. Those are all products of the mind. So when people utter ridiculous clichés like "Don't listen to your head; listen to your heart," what they are really saying is "Don't listen to your head; listen to your head." Our culture has so many ridiculous clichés pertaining to the heart it is not funny. They fail to understand that the heart, as an organ, can do nothing but pump blood through your body. All the things they attempt to attribute to it are products of your mind. And people blindly believe these statements because they are uttered all the time without thought. I am sure I have even wrote some erroneous things toward the same end, and for that I repent. It is the expression of false information. May we grow in our understanding and renew our minds with the truth, ever separating ourselves from the lies and misinformation.
The Bible makes no distinction between the heart and the mind. It is never talking about the organ beating within your chest.
