Nun komm, der heiden heiland is a Lutheran chorale that translates to 'Now come, Savior of the heathens' and is based on a 15th-century hymn by Martin Luther. This hymn is significant in the context of Bach's compositions as it embodies the themes of redemption and salvation, central to Lutheran worship. Bach frequently incorporated this chorale into his works to connect his music with the spiritual and liturgical practices of the Lutheran Church, making his compositions not just artistic expressions but also religious statements.
