THE HEART
the greatest power is the heart of god
the second greatest power is the heart of man
HEART is the center of the physical, mental, and spiritual life of humans. This contrasts to the normal use of kardia ("heart") in Greek literature outside the Scriptures. The New Testament follows the Old Testament useage when referring to the human heart in that it gives kardia a wider range of meaning than it was generally accustomed to have.
First, the word heart refers to the physical organ and is considered to be the center of the physical life. Eating and drinking are spoken of as strengthening the heart. As the center of physical life, the heart came to stand for the person as a whole.
The heart became the focus for all the vital functions of the body; including both intellectual and spiritual life. The heart and the intellect are closely connected.
the heart being the seat of intelligence:
The heart is connected with thinking:
"To set one's heart on" is the literal Hebrew that means to give attention to something, to worry about it. To call to heart (mind) something means to remember something. All of these are functions of the mind, but are connected with the heart in biblical language.
Closely related to the mind are acts of the will, acts resulting from a conscious or even a deliberate decision.
Ananias contrived his deed of lying to the Holy Spirit in his heart. The conscious decision is made in the heart.
Connected to the will are human wishes and desires. Romans 1:24 describes how God gave them up "through the lusts of their own hearts, to dishonor their own bodies."
David was a man after God's "own heart" because he would "fulfill all" of God's will.
Not only is the heart associated with the activities of the mind and the will, but it is also closely connected to the feelings and affections of a person. Emotions such as joy originate in the heart. Other emotions are ascribed to the heart, especially in the Old Testament. Discouragement or despair is described by the phrase "heaviness in the heart" which makes it stoop.
Another emotion connected with the heart is sorrow.
The heart is also the seat of the affection of love and its opposite, hate. In the Old Testament, for example, Israel is commanded:
Jealousy is described as coming from the heart.
love is based in the heart.
Finally, the heart is spoken of in Scripture as the center of the moral and spiritual life. The conscience, for instance, is associated with the heart. In fact, the Hebrew language had no word for conscience, so the word heart was often used to express this concept:
The Revised Standard Version translates the word for "heart" as "conscience" in 1 Samuel 25:31. In the New Testament the heart is spoken of also as that which condemns us (1 John 3:19-21).
All moral conditions from the highest to the lowest are said to center in the heart. Sometimes the heart is used to represent a person's true nature or character. Samson told Delilah "all his heart". This true nature is contrasted with the outward appearance: "man looks on the outward appearance, but the Lord looks on the heart"
On the negative side, depravity is said to issue from the heart:
Jesus said that out of the heart comes evil thoughts, murder, adultery, fornication, theft, false witness, slander. Defilement comes from within rather than from without.
Because the heart is at the root of the problem, this is the place where God does His work in the individual. For instance, the work of the law is "written in their hearts," and our conscience is the proof of this.
The heart is the field where seed (the Word of God) is sown.
In addition to being the place where the natural laws of God are written, the heart is the place of renewal. Before Saul became king, God gave him a new heart. God promised Israel that He would give them a new spirit within, take away their stony heart and give them a heart of flesh.
a person must believe in the heart to be saved
Finally, the heart is the dwelling place of God.
Every snowflake has a tiny piece of dust at its core. Yes, every snowflake has a "dirty heart". In the spiritual realm, when the blood of Christ is applied to the heart of an unbeliever, it cleanses him from all sin. Not a speck of defilement remains, for God removes every stain and washes him even whiter than snow.
A Hindu trader in India once asked a missionary, "What do you put on your face to make it shine?" With surprise the man of God answered, "I don't put anything on it!" His questioner began to lose patience and said emphatically, "Yes, you do!" All of you who believe in Jesus seem to have it. I've seen it in the towns of Agra and Surat, and even in the city of Bombay." Suddenly the Christian understood, and his face glowed even more as he said, "Now I know what you mean, and I will tell you the secret. It's not something we put on from the outside but something that comes from within. It's the reflection of the light of God in our hearts.
Emerson said, "A man is what he thinks about all day long."
The Roman emperor Marcus Aurelius put it this way, "A man's life is what his thoughts make of it."
William James said, "The greatest discovery of my generation is that human beings can alter their lives by altering their attitudes of mind."
In the Bible, we find: "As a man thinks in his heart, so is he."
