"You say you are a Christian; who was the father of Jesus Christ?"
"I don't know"
"Who was his mother?"
"I don't know"
"When did He live?"
"I don't know"
"How old was He when He died?"
"I don't know"
"How did He die?"
"I don't know"
"Well, you aren't a good Christian! You don't know who was the father of Jesus, or who was His mother, or when He lived, or when He died, or how He died. What do you know?"
Then the rough, but genuine Christian man lifted his head and looking around those taunting him in the face, replied, "I know that He saved me."
