John Newton - The Trembling Jailer

A Believer, free from care,
May in chains, or dungeons, sing,
If the Lord be with him there;
And he happier than a king:
Paul and Silas thus confined,
Though their backs were torn by whips,
Yet possessing peace of mind,
Sung his praise wish joyful lips.

Suddenly the prison shook,
Open flew the iron doors;
And the jailer, terror-struck,
Now his captives' help implores:
Trembling at their feet he fell,
Tell me, Sirs, what must I do
To be saved from guilt and hell?
None can tell me this but you.

Look to Jesus, they replied,
If on Him thou canst believe;
By the death which he has died,
Thou salvation shalt receive:
While the living word he heard,
Faith sprung up within his heart;
And released from all he feared,
In their joy his soul had part.

Sinners, Christ is still the same,
O that you could likewise fear!
Then the mention of his name
Would be music to your ear:
Jesus rescues Satan's slaves,
His dear wounds still plead, Forgive!
Jesus to the utmost saves;
Sinners, look to him and live.

John Newton
