There is an old story about a bandit...
There is an old story about a bandit in the Far East who was badly injured and taken to a Christian mission hospital. Having received excellent care, he decided he would never again rob a Christian. Word got around about his resolve; therefore, when he tried to rob someone that person would profess to be a Christian. How could he tell who was really a Christian? The man went back to the mission hospital and asked the question. The missionaries said that anyone who was a Christian ought to be able to recite the Lord's Prayer and the Ten Commandments.
