Finally, for your intellectual and devotional interest, here is the entire text of the anthem. I can assure you that the music will be just as beautiful and evocative as the words.
O Thou sweetest Source of gladness,
Light’s all lovely fountain head,
Who, alike in joy and sadness,
Leavest none unvisited;
Breath of God head, highest King,
Who upholding everything,
Wilt uphold, with love undying.
Hear, O hear me humbly crying.
From thy throne, as April shower
Thou descendest, heavenly One,
Freighted with thy sevenfold dower,
From the Father, and the Son.
Bring me noble Guest divine,
God’s own blessings they are thine,
Freely dealt at thy good pleasure,
Fill me in abundant measure.
Save, uphold, and go before me,
Fainting, be my staff and rod:
Dying, to new life restore me,
Buried, be my grave, O God:
From the dust when I arise,
Come, exalt me to the skies,
Where thou within realms supernal
Feed thy saints with joys eternal.
-Paul Gerhardt (1607-1676),
