John 16:25: And the prisoners heard them

They heard the strange unwonted sound
Of joy enhanced by smart and woe,
Of liberty in fetters found:
The voice of saints who Jesus know,
Which comforts every soul that mourns,
And dungeons into temples turns.

They heard the voice so rarely heard
By wretches poor in bonds confined,
The voice which spake their God prepared
Imprison'd spirits to unbind,
Out of their sinful sleep to raise,
And fill their hearts with prayer and praise.
