Gene Higgins explores the life, faith, and musical legacy of Johann Sebastian Bach, examining how his Lutheran faith and devotion to Christ fundamentally shaped his compositions. He addresses major themes including Bach's view of music as a tool for proclaiming the Gospel and glorifying God (noted by the initials SDG), the historical and spiritual significance of his major works—such as the St. Matthew Passion and the Mass in B minor—and the broader cultural and theological impact of his music across centuries, including its resonance in secular societies like Japan.
