" Simply, singing may be the one human activity that most perfectly combines heart, mind, soul, and strength. Almost everything else we do requires at least one of these fundamental human faculties: the heart, the seat of the emotion and the will; the mind, with which we explore and explain the world; the soul, the heart of human dignity and personhood; and strength, our bodies’ ability to bring about change in the world. But singing (and maybe only singing) combines them all. When we sing in worship, our minds are engaged with the text and what it says about us and God, our hearts are moved and express a range of emotions, our bodily strength is required, and—if we sing with “soul”—we reach down into the depths of our beings to do justice to the joy and heartbreak of human life. To sing well—not in the sense of singing in perfect tune or like a professional, but in this sense of bringing heart, mind, soul, and strength to our singing—is to touch the deepest truths about the world. It is to know wisdom. And it’s also to develop the courage and character to declare that God is this good, that we are this in need of him, that we are this thankful, that we are this committed to be part of his story. "
