An unnamed girl from Jerusalem was captured as a slave and taken to Syria. Away from her home and family, she served as a foreign missionary in the house of Naaman, the captain of the armies of Syria. Though Naaman was a mighty man of war, he was afflicted with leprosy.
This little servant girl had good news to share. She knew of a man in her home country named Elisha, a prophet of God. She knew that Elisha had the power of God on his life and that if Naaman would visit the prophet, then he could be healed.
This little missionary girl directed her master to someone who could more powerfully show God’s might and message. Even though she was in a foreign land—against her will—she loved the people enough to share God’s good news. She had such a testimony among the people with whom she worked that they acted upon the information she gave and never questioned her motives.
