The central organ of the human body is the heart. It circulates the blood throughout the whole bodily system, pumping oxygen and nutrients to the other organs and pulling toxins away from them.
Yet we human beings have another "heart" a spiritual one that is the true center of our existence. Our spiritual heart is our identity. It is the foundation of our whole being, from which our desires, designs, purposes, will, thoughts, and attitudes originate.
Yet, as a result of the fall and our sinful nature, we all have symptoms of "heart disease," and we need to know how to become spiritually heart-healthy. As the Scriptures say, "The heart is deceitful above all things, and desperately wicked; who can know it?" (Jeremiah 17:9). Every spiritual, mental, and emotional matter and many physical ones is rooted in the heart. The state of our spiritual heart affects all aspects of our daily living. Therefore, the condition of our heart will be the condition of our life.
