One thing I would say is that the heart is NOT the mind!
The journey from the head to the heart is the most important, and many have the things of God in their heads, but do not have them in their hearts!
You would be one very confused believer if you were speaking about the physical organ.
Heart more than often refers to the mind.
For it is with your heart(organ?
) that you believe and are justified, and it is with your mouth that you profess your faith and are saved. Rom 10:10
Only then would we be adhereing to Gods command as the prophet Jeremiah once said.
You will seek me and find me when you seek me with all your heart. Jer 29:13
It is in this sense that the word “heart” is used in the Scriptures of Truth.
Actually a wonderful book which speaks a great deal of the heart is the Proverbs...lets look a few verses.
"My son, give me thine heart, and let thine eyes delight in my ways" (Pro 23:26).
What do you think the heart is referring to here?
Heart:
Eyes:
Ways:
Death and destruction are before the Lord: how much more the hearts of the children of men (Pro 15:11).
Heart:
Referring to an undesirable guest.
"Eat and drink, says he, but his heart is not with thee." Pro 23:7
Heart:
These passages really don’t need interpreting! (But you are more than welcome!)
The word “heart” is used today in the same way it was back then. I can hear what you say, your actions and how you appear to me as a person, but I will never know what is in your heart: how you think and feel.
The heart speaks to the intellectual and emotional disposition of a person. When the mind and feeling is stimulated by the Spirit Word of God only then can we think in harmony with Him.
Such passages like Phil 2 "Let this mind be in you..."
You could be smiling at me but inside thinking all manner of evil...only God and Jesus Christ can look upon the heart (mind) to see the purity of thought passing through it.
Our awareness that all hearts are open and naked to God is known to all His true children.
"The fining pot for silver, and the furnace for gold; but the Lord trieth the heart" (Pro 17:3).
The analogy being applied is the revealing of a mind which through heat of trials is purged of dross like the fining of metals (of our hearts).
There is a major difference here which must be stated. I can take metal and purify through my own actions but the purifying of the human heart is a work made without hands. Only God can test us and cleanse us of sin and every impure thought.
The process of fining the heart (metals) is far more complex think people might think.
Removing dross from metal is one thing but introducing new hopes, new desires and in fact the very “newness of life” is another.
The heart (mind) must be responsive and the profound reality of this fact is spoken through these words in Isaiah 50:5
"The Lord God hath opened my ears, and I was not rebellious." [Isa 50:5]
Some of us are rebellious to the extent of making the Word of God viod in our lives. God gave to Saul a new heart so that he began his reign well, but he became rebellious and his heart turned to evil. His fall expresses perfectly the illustration of the proverb,
"A sound heart (mind) is the life of the flesh, but envy is the rottenness of the bones." [Pro 14:30]
Perhaps he illustrated another proverb, well known to all readers though not much heeded in the world:
"He that is proud of heart (mind) is an abomination to the Lord." [Pro 16:5]
The heart is the source of reasoning and when a person is able to control their natural impulses in the flesh because of the fear of consequenses the heart will be revealed either good or evil.
The heart is the symbol of mind, thought, action and feeling which are all controlled by the heart of man. The diligent control of the heart in order that your character may develope in harmony with the divine will is essential for our well being. The heart needs regular guidance of thought and feeling and this is what is meant by "keeping the heart with all diligence".
The inmost thoughts of the heart are the greatest clarity of character.
"As he thinketh in his heart, so is he", or so will he be (Pro 23:7).
Where do we think?
The mind..and it is desireable to ensure the stream of thought passing through our minds is as clean as possible.
Take care
