The great cathedrals of Europe are among the finest architectural masterpieces known, and their inspiration comes from Jesus. It was a servant of Christ, [composer Johann Sebastian] Bach (a man who dedicated every note he wrote to the glory of Jesus Christ), who changed Western music for all time.
Had Jesus never been born, art would depict only the finite. The attempt to capture the Infinite on canvas or in stone would never have been introduced. In short, had Jesus never come, the world would be poorer, even in the realms of art and music.
