Thanks. Derek Prince was an amazing man. When he first launched his ministry DPM, it made a loss of ten thousand dollars a month because it was non profit making. The Lord told Derek to reach out to the poor and charge them nothing but charge those that could afford (for his books) and that is how he stopped making such a huge loss which was a massive amount of money all those years ago.
Derek and Lydia were both incredibly intelligent and had very promising bright future careers ahead of them but the Lord called them and they put their lives at risk, saved many children, called many people home to the Lord and saw Israel born. When they could have been earning a lot of money they scraped by with very little money and the Lord provided.
