The Three Letters That Changed Everything

Johann Sebastian Bach composed over a thousand works in his lifetime — cantatas, fugues, concertos, and oratorios that would shape Western music for centuries. He wrote pieces for Sunday worship services, for royal courts, for students learning keyboard technique. Some were grand. Some were ordinary. But at the bottom of nearly every manuscript, whether sacred or secular, Bach inscribed three small letters: S.D.G.

Soli Deo Gloria. To God alone be the glory.

Those three letters were not decoration. They were a declaration of purpose. Bach did not distinguish between his "important" compositions and his routine ones. A practice exercise for a student received the same signature as the Mass in B Minor. Every note, every measure, every hour of labor was oriented toward the same end.

This is what purpose does to a life. It does not elevate only the dramatic moments. It transforms the ordinary ones. When you know why you exist, Monday morning carries the same weight as Sunday morning. The email you write at your desk bears the same signature as the prayer you whisper in the sanctuary.

The Apostle Paul understood this. "Whatever you do," he wrote, "do it all for the glory of God." Not just the beautiful work. Not just the visible work. Whatever you do.

You may never compose a masterpiece. But the God who gave Bach his purpose has given you yours. The question is not whether your work is significant. The question is whether you have signed it.
