Johann S. Bach (1685–1750)

Come, Holy Spirit, God and Lord!
Let all your graces be outpoured
On each believer’s mind and heart;
Your fervent love to us impart.

Lord, by the brightness of Your light,
You in the faith do men unite
Of every land and every tongue;
This to Your praise, O Lord, be sung.

From every error keep us free;
Let none but Christ our master be,
That we in living faith abide,
In Him with all our might confide.

Lord, by Your power prepare each heart
And to the weakness strength impart,
That bravely here we may contend,
Through life and death to You ascend.
