The heart is a set of 4 chambers, with walls built up of muscle. When the muscle relaxes, blood flows from the top to the bottom. When the muscle contracts blood pumps out into the body. Every drop of blood flows through the heart to the rest of our body, providing oxygen and nutrients to keep us alive. If something happens to your heart, your life can be at risk. Bullet proof vests and armor protect your heart from weapons. Eating well and exercise protect our heart from disease. We spend a lot of time, energy, and money to protect our physical hearts. How much do you do to protect your figurative heart?
Guard your heart above all else, for it is the source of life. Proverbs 4:23 HCSB
Just like our physical heart, our figurative heart needs protection. Perhaps we need to block dangerous things from getting in…what we watch, read, and listen to; where we go and what we do; the people we surround ourselves with. Perhaps we need to put up a physical barrier like a vest or be sure we give our hearts plenty of good food and exercise.
