Henry van Dyke Quote

Oh, come as comes the morn.
Serene and strong and full of faith, America, arise,
With steady hope and mighty help to join thy brave Allies.
O dearest country of my heart, home of the high desire,
Make clean thy soul for sacrifice on Freedom's altar-fire:
For thou must suffer, thou must fight, until the warlords cease,
And all the peoples lift their heads in liberty and peace.

Liberty Enlightening the World (1917)
