The human heart is an amazing organ. This fist-sized pumping station weighs between 7 and 15 ounces. Daily it beats around 100,000 times and pumps 2,000 gallons of blood through the 60,000 miles of blood vessels in our bodies! With such a strategic assignment and heavy workload, it’s understandable why heart health is central to the wellbeing of the entire body. Medical science encourages us to pursue healthy habits because the condition of our heart and the quality of our health go together.

While medical science speaks authoritatively about our physical hearts, God speaks with even greater authority about a “heart” of another kind. He addresses the mental, emotional, spiritual, and moral “center” of our being. Because the heart is the central processing unit of life, it must be protected: “Guard your heart, for everything you do flows from it” (Proverbs 4:23). Safeguarding our hearts will help us with our speech (v. 24), compel us to be discerning with our eyes (v. 25), and choose the best paths for our feet (v. 27). Regardless of age or stage of life, when our hearts are guarded, our lives are preserved, our relationships are protected, and God is honored.
