John Milton Quote

Doth God exact day-labour, light denied,
I fondly ask; but patience to prevent
That murmur, soon replies, God doth not need
Either man's work or his own gifts, who best
Bear his mild yoke, they serve him best, his state
Is kingly. Thousands at his bidding speed
And post o'er land and ocean without rest:
They also serve who only stand and wait.

Sonnet 16 'When I consider how my light is spent' (1673)
