"And Naomi said to her daughter-in-law, 'May he be blessed of the Lord who has not withdrawn his kindness to the living and to the dead.'  Again Naomi said to her, 'The man is our relative, he is one of our closest relatives.'  Then Ruth the Moabites said, 'Furthermore, he said to me, "You should stay close to my servants until they have finished all my harvest."'  And Naomi said to Ruth her daughter-in-law, 'It is good, my daughter, that you go out with his maids, lest others fall upon you in another field.'  So she stayed close by the maids of Boaz in order to glean until the end of the barley harvest and the wheat harvest.  And she lived with her mother-in-law."

Imagine the dropped barriers that Ruth is experiencing.

She meets a Hebrew family and falls in love.  Then her husband dies.  Then the only link moves out of the land where Ruth is most familiar.

Ruth has every reason to expect an outcast life.  She does not have a "real" family tie to Naomi anymore. 

Yet Naomi calls her and treats her like a daughter.
Boaz treats her as a Hebrew widow, not a foreigner.
The servants treat her as a fellow gleaner, not a leach taking advantage.

This is where we see God:
Hospitality is spent on Ruth so that she is made to feel like a close family member.  She is not regarded as less than an heir just because she was not born an heir.  Jesus promised the same to us.

Because of the love of God, we are joint heirs with Christ.  God does not consider our lack of dowry as something to hold us back, but instead, lavishes His love to us.
