RUTH & ESTHER. Is God really sovereign? Can individual people make a difference in His world? A young girl named Ruth and a middle-aged man named Boaz answer yes to both questions in the violent days of Israel's judges-and the couple goes on to play a crucial part in God's plan. Over 600 years later, a Jew named Mordecai and his cousin Esther save their nation by also saying yes. Today these stories still inspire believers to affect the world by trusting God.
