I definitely felt the need to add the story of George Mueller, who lived in England in the 1800's, building orphanages for the run-aways, and wandering children at that time in England. George had approximately 10,024 orphans during sixty years running the orphanages. He said that about 3,000 of those orphans came to have a relationship with God during that time. Also he had all of the monetary aspects of his ministry covered from start to finish, never worrying about the whereabouts of money.
