The principle stated here is the key to improving one's physical health just as surely as it will improve one's spiritual health. The sense of the usage of "heart" here is synonymous with the English word "within," thus, what is within a person's mind is hidden from view when one looks from outside. Appearances can be very deceiving because what is within may be far different from what another can perceive. A person may appear smiling and jovial, but he may only be acting to achieve a scheme that ultimately profits him. Therefore, he is using others to achieve his end.

Eating: How Good It Is! (Part Five)
Taken together, James 4:5-6, Proverbs 23:6-7, and Romans 12:3 indicate that what a person thinks of himself is clearly important to God. We all have an image of ourselves that we carry about in our heart. We tend to think of ourselves in a certain way, a persona that we want to project to others. This is not wrong of and by itself. Because we love God, we should greatly desire to project to others an image of Him that is pleasing to Him. What is wrong, though, is that too often the image we project has its basis in some area of pride.
Most of us do not really understand exactly what image we project to others. In other words, we often do not succeed in projecting the impression we want others to have of us. For instance, it is easy for a person to think he is projecting an image of one who is serious, quiet, and contemplative, when the reality is that others consider him to be stern and condemning. A wide divergence of conclusions about an individual is actually quite common. While those who know us may see the same person, they take away different impressions, which results in different assessments.
The image that we try to project is what we think we ought to project for someone in our position. As mentioned earlier, the problem in most of this image-projection is that it is driven by pride, and "God resists the proud."
Since so many commentators believe that pride is the father of all sins, it is surprising that "pride" appears only 49 times in Scripture and only three times in the New Testament. The Hebrew term ga'on in a good sense indicates "majesty" or "excellence." However, most of its usages are negative, as the antonym of "humility." It is associated with arrogance, insolence, evil behavior, and perverse speech.
The Greek word translated pride is tuphoo. Its literal meaning is "to envelop in smoke," but metaphorically, it indicates "conceit," "lifted up," and "high-mindedness." The word pictures a person using smoke as a screen to conceal the image he does not want the public to see.
Pride includes a degree of haughtiness, a measure of contempt for others. It is a matter of the heart that is buried under the surface. However, though the one who suffers from it may appear to walk in downcast humility, all the while in his heart he has vast contempt for God and fellow man, which is revealed in his lack of the fear of God and general, overall disobedience.
Why is God so against pride? A person infected by this deadly quality so admires himself that he is unaware of his paucity of vastly more important qualities. A proud person cherishes independence so that he will not be beholden to others. He is so preoccupied with his self-proclaimed goodness that he never realizes that he has any sin from which he needs to be saved, and thus he will not be corrected. He believes that he is above it all.
