Milton

I had heard the name, but had not read any of his work. I just came across the beautiful line:
"they also serve who only stand and wait".

The strength of these words increased when I found that Milton had written these as the concluding lines of a poem about his blindness!

On His Blindness

When I consider how my light is spent

Ere half my days in this dark world and wide,

And that one Talent which is death to hide

Lodged with me useless, though my soul more bent

To serve therewith my Maker, and present

My true account, lest He returning chide,

"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."
