When did "sentimental" become a pejorative barb? I do not at all share the notion that a piece of music, or a poem, or a film that bypasses the brain and aims straight for the heart. . . should automatically be heaped with scorn. I think it is symptomatic of a sad and dangerous impoverishment of spirit.
Confession is good for the conscience, but it usually bypasses the soul.
Whereas story is processed in the mind in a straightforward manner, poetry bypasses rational thought and goes straight to the limbic system and lights it up like a brushfire. It's the crack cocaine of the literary world.
We live in a church culture that has a dangerous tendency to disconnect the grace of God from the glory of God. Our hearts resonate with the idea of enjoying God's grace. We bask in sermons, conferences, and books that exalt a grace centering on us. And while the wonder of grace is worthy of our attention, if that grace is disconnected from its purpose, the sad result is a self-centered Christianity that bypasses the heart of God.
Music bypasses the conceptual mind. Music does not give you food for thought.
