Once to every man and nation

Once to every man and nation
Comes the moment to decide,
In the strife of truth and falsehood,
For the good or evil side;
Some great cause, God's new Messiah,
Off'ring each the bloom or blight,
And the choice goes by forever
Twixt that darkness and that light.

Though the cause of evil prosper,
Yet 'tis truth alone is strong;
Though her portion be the scaffold,
And upon the throne be wrong:
Yet that scaffold sways the future,
And behind the dim unknown,
Standeth God within the shadow
Keeping watch above his own.

James Russell Lowell
