...No heart but of the Spirit taught...

O Lord, we know it matters not
How sweet the song may be;
No heart but of the Spirit taught
 Makes melody to Thee.

Then teach Thy gathered saints, O Lord,
To worship in Thy fear;
And let Thy grace mould every word
That meets Thy holy ear.

Thou hast by blood made sinners meet
As saints in light, to come
And worship at the mercy-seat,
 Before th’ eternal throne.

Thy precious name is all we show,
Our only passport, Lord;
And full assurance now we know,
Confiding in Thy word.
