A notorious infidel delivered and eloquent sermon on Christianity, and then asked if there were any questions from the audience.
An old man with a half-eaten orange in his hand mounted the platform, stood before the audience until he had eaten the orange, and turning to the speaker, he said:
“I have just one question, sir. Can you tell me whether the orange I just ate was sweet or sour?”
“Don’t be ridiculous, old man” said the speaker rudely. “How on earth can I know if that orange was sweet or sour. I didn’t eat it, did I ?”
“Exactly,” said the old man with satisfaction. “I was a drunkard and a gambler for many years until I came to Christ and proved His love and mercy. But how can you speak about Him when you have never tasted Him yourself?”
