How do we know God's purpose is fulfilled in Ruth's story?

God's purpose as articulated in the Book of Ruth is evident in how He orchestrates events to fulfill His plan of redemption. Ruth, a Gentile, finds grace in the eyes of Boaz, which underscores the inclusion of the nations into the fold of God's elect. This story serves not only as a historical account but also as a theological testament that God's mercy extends beyond Israel to all who are called according to His purpose. It beautifully supports the doctrine of election and reveals the depths of God's unwavering faithfulness in seeking and saving His people.
