Du Friedefürst, Herr Jesu Christ, BWV 1102
Ein silberner Lichtstrahl fällt in die innerste Kammer einer Höhle
Eisvögel suchen ihren Weg durch beschneites Schilf
Zwischen hellgrünen Hügeln sammelt sich Schmelzwasser
Kinder spielen an einem Bach voller Dotterblumen
Unter blühenden Bäumen atmen Liebende den Duft der Erde ein
Ein Sommerregen fällt auf weites, grünes Land
Eine Menschenmenge wird von heftigem Sturm überrascht
Strahlen sinkender Sonne zaubern ein Netz auf tiefblaues Wasser
Menschen verschiedenen Alters tragen Holz für ein Herbstfeuer zusammen
Die Steine eines uralten Heiligtums fangen an zu klingen
