Erhalt Uns, Herr Geistliche Lieder (Wittenberg, Germany: 1543) (🔊 pdf nwc).

Matthias Loy (1828–1915)

Lord, open Thou my heart to hear
And through Thy Word to me draw near;
Let me Thy Word e’er pure retain,
Let me Thy child and heir remain.

Thy Word doth deeply move the heart,
Thy Word doth perfect health impart,
Thy Word my soul with joy doth bless,
Thy Word brings peace and happiness.

To God the Father, God the Son,
And God the Spirit, Three in One,
Shall glory, praise, and honor be
Now and throughout eternity.
