'I am sure that I have run more swiftly with a lame leg than I ever did with a sound one. I am certain that I have seen more in the dark than I ever saw in the light, - more stars, most certainly, - more things in heaven if fewer things on earth. The anvil, the fire, and the hammer, are the making of us; we do not get fashioned much by anything else. That heavy hammer falling on us helps to shape us; therefore let affliction and trial and trouble come.'
Charles Spurgeon in Zack Eswine, Spurgeon's Sorrows, p.139.
