Our study of Ruth 2 continues. We see that Boaz called Ruth "daughter" and promised her a "full reward" because she left her parents and home country to come be a part of a people (Israel) she had not known before.
The same is true for us when we accept the gift of salvation and become a child of God, part of the body of the Lord Jesus Christ. By leaving this wicked world system and becoming born again into a new kingdom, we also receive a full reward. God is our reward! We are joint heirs with Jesus!
