A professor of communism demonstrated at a meeting that Jesus was nothing but a magician. The professor had before him a pitcher of water. He put a powder in it and it became red. "This is the whole miracle," he explained. "Jesus had hidden in his sleeves a powder like this, and then pretended to have changed water into wine in a wonderful manner. But I can do even better than Jesus; I can change the wine into water again." And he put another powder in the liquid. It became clear. Then another powder and it was red again.
A Christian stood up and said, "You have amazed us, comrade professor, by what you are able to do. We would ask only one thing more of you - drink a bottle of your wine!" The professor said, "This I cannot do. The powder was a poison." The Christian replied, "This is the whole difference between you and Jesus. He, with His wine, has given us joy for two thousand years, whereas you poison us with your wine." The Christian went to prison. But news of the incident spread very far and strengthened many of the faith.
