I Heard the Bells on Christmas Day

This is by Henry Wadsworth Longfellow. Appearently, he wrote it during the Civil War, after his son was badly wounded in the fighting.

I heard the bells on Christmas day
Their old familiar carols play,
And wild and sweet the words repeat
Of peace on earth, good will to men.

I thought how, as the day had come,
The belfries of all Christendom
Had rolled along the unbroken song
Of peace on earth, good will to men.

And in despair I bowed my head
'There is no peace on earth,' I said,'
For hate is strong and mocks the song
Of peace on earth, good will to men.'

Then pealed the bells more loud and deep:
'God is not dead, nor doth He sleep;
The wrong shall fail, the right prevail
With peace on earth, good will to men.'

Till ringing, singing on its way
The world revolved from night to day,
A voice, a chime, a chant sublime
Of peace on earth, good will to men.
