Tennis champions and devout Jehovah's Witnesses Venus and Serena Williams look formidable on the cover of The New York Times Magazine. In the article Isha Price, the half-sister of Venus, 32, and Serena, 30, describes what it's like to go door-to-door with her sisters trying to convert people to the religion. "I have been out in service with Venus and Serena," said Isha who is their half-sister from their mother's previous marriage. "It's a trip too. People be blown away," she said.
