Ruth, a Moabitess, stands out as a refreshing contrast to the declension of Israel in the time of the Judges. This book is beautifully designed by God to show how His grace can sustain a faithful testimony of individuals at a time when the general condition of things is low and naturally discouraging.
Besides this, the book pictures God's recovering grace in regard to Israel after she has departed from God in disobedience and become desolate. The blessing for both Ruth and Naomi come from the intervention of Boaz, kinsman redeemer, type of the Lord Jesus, who is the Restorer of Israel and also the Savior of Gentiles.
Since Christ is the Restorer, then the book also holds instruction as to how individual believers are restored to God after failure and departure. May we discern and benefit by the many applications of scripture, not confining our thoughts to the application that most appeals to us, but considering all that God is seeking to make known to us.
