As a young man preparing to go to China, Hudson Taylor determined to learn to live by faith alone while he was still in England. His resolve was "to learn before leaving England to move man through God by prayer alone." He worked for a doctor and was paid quarterly. When the time drew near to receive his salary, Taylor was disturbed that his employer said nothing about it. Taylor had only one half-crown piece, but he determined not to break his resolution and ask for his salary.
While visiting a needy home on the Lord's Day, Taylor felt led of God to give his last coin to the needy family. The next day he received an anonymous gift through the mail, four times what he had given to the poor! The following Saturday, the doctor finished up his work and said, "Taylor, is not your salary due again?" Taylor told him that it was and became disappointed when he learned that the doctor had forgotten about the salary due and sent all his funds to the bank! He prayed about the matter (for he had bills of his own to pay) and left it with the Lord.
That evening, the doctor visited him and said that one of his richest patients had come over after hours to pay his bill! He gave the money to Taylor, who rejoiced. He had learned he could trust God and therefore go to China as a missionary.
