A preacher was speaking from the text, “The blood of Jesus Christ his Son cleanseth us from all sin.” Suddenly he was interrupted by an atheist who asked, “How can blood cleanse sin?”
For a moment the preacher was silent; then he countered, “How can water quench thirst?”
I do not know,” replied the infidel, “but I know that it does.”
“Neither do I know how the blood of Jesus cleanses sin,” answered the preacher, “but I know that it does.”
