Why is the heart important? Well, from a biological point of view, it sustains life. Without the heart pumping the life-giving blood, the body would quickly die.
The same is true spiritually. The heart is the well-spring of life. When it is allowed to become infirm with sin, a person’s spiritual life quickly deteriorates. This is why God, our concerned heavenly parent, tells us to guard our hearts with all our diligence, since he knows from it come the issuance of life.
