Nicky Cruz: David Wilkerson 'Never Lost His Heart'

"Wilkerson 'never lost his heart' for the world's needy people, Cruz said. The two of them worked together to run Teen Challenge, a network of rehabilitation centers dedicated to healing drug and alcohol addiction and other 'life-controlling problems.' Later, Wilkerson moved back to New York to start Times Square Church, and Cruz set out on his own evangelistic ministry."
