Volunteers are wanted! hear the stirring call,
O be swift to answer, comrades, one and all;
Girding on your armor, haste to march away,
For the Lord is calling,
To the front today!
Refrain
Away to the battlefield, away, away!
The King calls for soldiers in His ranks today;
Hear the bugles calling, into line be falling,
Forth to the battlefield, away, away!
Volunteers are wanted! valiant men and true,
In the ranks, my brother, there is room for you;
Christ is the commander, let us all obey
When He gives the order,
To the front today!
Refrain
Volunteers are wanted! for on land and sea
Satan’s starving bondmen clamor to be free;
Hasten to their rescue; if you still delay
Blood-bought souls must perish,
To the front today!
Refrain
Volunteers are wanted! on the battle plain
Soldiers brave are falling, ne’er to fight again;
Who will take their places in the deadly fray?
Who will march with Jesus
To the front today?
Refrain
