The heart, in biblical terms, is not part of who we are but the center of who we are. Our heart is what defines and directs us. That is why Solomon tells us to “keep [the] heart with all vigilance, for from it flows the springs of life” (Prov. 4:23).2 The heart is a matter of life. It is what makes us the human being each of us is. The heart drives all we do. It is who we are.3
