COMMENTARY
The barracks where Corrie ten Boom and her sister Betsy were kept in the Nazi concentration camp Ravensbruck were terribly overcrowded and flea-infested.
They had been able to miraculously smuggle a Bible into the camp, and in that Bible they had read that in all things there were to give thanks, and that God can use anything for good.
Corrie’s sister Betsy decided that this meant thanking God for the fleas.
