Be vigilant, and quit themselves like men...

The tryals that those men do meet withal,
That are obedient to the Heavenly call,
Are manifold, and suited to the flesh,
And come, and come, and come again afresh;
That now, or some time else, we by them may
Be taken, overcome, and cast away.
Oh, let the Pilgrims, let the Pilgrims then,
Be vigilant, and quit themselves like men.

-John Bunyan
