From CHRISTMAS BELLS by Henry Wadsworth Longfellow

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!

***
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.”
