Lancashire Henry T. Smart, 1836 (🔊 pdf nwc).

Ernest W. Shurtleff (1862-1917)

Lead on, O King eternal,
The day of march has come;
Henceforth in fields of conquest
Thy tents shall be our home.
Through days of preparation
Thy grace has made us strong;
And now, O King eternal,
We lift our battle song.

Lead on, O King eternal,
Till sin’s fierce war shall cease,
And holiness shall whisper
The sweet amen of peace.
For not with swords’ loud clashing,
Nor roll of stirring drums;
With deeds of love and mercy
The heav’nly kingdom comes.

Lead on, O King eternal,
We follow, not with fears,
For gladness breaks like morning
Where’er Thy face appears.
Thy cross is lifted over us,
We journey in its light;
The crown awaits the conquest;
Lead on, O God of might.
