Francis Schaeffer was once asked the question, “what would you do if you met a really modern man on a train and you had just an hour to talk to him about the gospel?”
He replied, “I’ve said over and over, I would spend 45-50 minutes on the negative, to really show him his dilemma—that he is morally dead—then I’d take 10-15 minutes to preach the Gospel. I believe that much of our evangelistic and personal work today is not clear simply because we are too anxious to get to the answer without having a man realize the real cause of his sickness, which is true moral guilt (and not just psychological guilt feelings) in the presence of God.”
