George Muller had run and orphanage in England in the early 1800s that cared for 5,000 children. He had made a vow never to ask people directly for anything, but to ask God instead to inspire them to provide food, clothing, money, or whatever else was needed. He eventually received more that 50 million British pounds in donations, all without ever asking anybody for anything.
