Gaetano Donizetti (1797-1848)

Hark! ’tis the clarion sounding the fight,
Turn from each siren charmer.
Banners are waving, swords gleaming bright,
Gird on the heav’nly armor.
Stern is the conflict, fierce is the foe;
Cowards and traitors will backward go:
Brave men are wanted, hearts all aglow,
Wanted to battle for Jesus.

Refrain

Soldiers of God, we join you today,
Join in your grand endeavor.
Soldiers of God, advance to the fray,
For the truth is triumphant for ever.

Haste to the rescue; souls in their need
Loud for relief are calling;
Must they for ever hopelessly plead?
None hear the cry appalling?
Broken in spirit, wounded by sin,
Foemen around them, and fear within;
Speed ye to help them freedom to win;
Speed with the Gospel of Jesus.

Refrain

Soon ’twill be over, danger all past;
Ended the marches dreary.
After the warfare, rest comes at last,
Sweet rest for soldiers weary.
Crown after conflict, ease after pain:
Parting shall never be known again;
Joy everlasting all shall obtain,
All who are faithful to Jesus.

Refrain
