Thirteen years ago, I was called upon to calm a violent, suicidal teacher in his classroom. I last saw him in hospital the next day, sedated. He was twice admitted to a sanatorium after that. Yesterday for the first time, I heard from him again. He had been saved, he wrote, and "true to your prophetic words, God found me new strength in my weakness. I read over and over again that book you gave me. ... I'm now a Reverend. One of my favourite places is the so called mad house. It humbles me. I want to thank you Rev. God used you mightily."
