Stephen Nichols new book Getting the Blues promises to be a good read. The subtitle of the book is "What Blues Music Teaches Us about Suffering and Salvation." The idea that God communicates truth and beauty through music, art, science, etc is what is known as "common grace." By God's grace believer and unbeliever alike may enjoy the beauty of great art and the benefit of scientific advances. Anyway, I encourage you to read Dr. Nichols. He writes smart, accessable books.
