I love this story about Hudson Taylor.
He was a medical assistant that was training to go over to China to be a missionary. He was living in a very small apartment and was down to literally no money. He had not been paid for his work for the last 7 months but refused to say anything to the doctor he worked for. One day he was walking home trying to figure out how he was going to make his last couple of bucks stretch out to buy food and pay for rent. Suddenly he was woken from his thinking by a frantic man asking for help for him and his family. the man had 4 kids and no money and was trying to get some food. Hudson gave all of his money to the man and went home with nothing. He decided that instead of asking the doctor for money he would become dependent on God taking care of him. The day before his rent was due the doctor asked him if he had been paid recently, Hudson said no and the doctor told paid him for the last 7 months and then some.

I paraphrased a lot of the story, but it was cool to see his faith in that situation.
