The book of Ruth tells the story of a destitute foreigner who came to believe in Israel’s God and was welcomed into God’s people. By grace she was privileged to become an ancestor of Jesus Christ, the Savior of all peoples. The commentary focuses on the themes of God’s covenant; God’s loyalty, reflected in the lives of his faithful people; the theology of missions and evangelism; Boaz as a redeemer, prefiguring Jesus Christ; and the promise of eternal life. The commentary’s Christocentric hermeneutic elucidates the rich Gospel message of Ruth and its relevance for the church today. The author’s international perspective and decades of service as a pastor and professor have given him unique insights into the message of this neglected book.
