Book of RuthThe Book of Ruth, too, is about exile and return, land and people where encourages us to view our day-to-day lives as part of God's bigger plan for our lives and world. The theme of family continuity becomes the theme of national continuity. The Book of Ruth is the bridge between the era of Israel as family or tribe and Israel as nation. Far from being peripheral to the main narrative sequence of the Bible, Ruth dramatizes its principal theme: the continuity of this people in their land.
