Go, labor on, while it is day;
The world's dark night is hastening on;
Speed, speed thy work, -- cast sloth away!
It is not thus that souls are won.

2 Men die in darkness at your side,
Without a hope to cheer the tomb;
Take up the torch and wave it wide --
The torch that lights time's thickest gloom.

3 Toil on, faint not; -- keep watch and pray!
Be wise the erring soul to win;
Go forth into the world's highway;
Compel the wanderer to come in.

4 Go, labor on; your hands are weak;
Your knees are faint, your soul cast down;
Yet falter not; the prize you seek
Is near, -- a kingdom and a crown!

H. Bonar, 1857.
