I had a very limited knowledge of Corrie ten Boom until recently reading the Hiding Place and was pleasantly surprised to learn that she was involved in her own disability ministry. Consider this exchange (in her own words) of a conversation in a Nazi prison camp:

"Your other activities, Miss ten Boom. What would you like to tell me about them?"
"Other activities? Oh, you mean- you want to know about my church for mentally retarded people!" and I plunged into an eager account of my efforts at preaching to the feeble-minded.
The lieutenant's eyebrows rose higher and higher. "What a waste of time and energy!" he exploded at last. "If you want converts, surely one normal person is worth all the half-wits in the world!"
I stared into the man's intelligent blue-gray eyes: true National-Socialist philosophy I thought, tulip bed or no. And then to my astonishment I heard my own voice saying boldy, "May I tell you the truth, Lieutentant Rahms?"
"This hearing, Miss ten Boom, is predicated on the assumpition that you will do me that honor."
"The truth , Sir," I said, swallowing, "is that God's viewpoint is sometimes different from ours- so different that we could not even guess at it unless He had given us a Book which tells us such things."
I knew it was madness to talk this way to a Nazi officer. But he said nothing so I plunged ahead. "In the Bible I learn that God values us not for our strength or our brains but simply because He has made us. Who knows, in His eyes a half-wit may be worth more than a watchmaker. Or- a lieutenant."
