In chapter 2 we repeatedly hear Ruth called "The Moabite." The author's use of this title serves to heighten the tension for Ruth living in a foreign land. She's an outsider. She doesn't belong. There's no reason she should expect any grace or favor from the people she is living with (remember: the Moabites were ancient enemies of Israel!).
Yet, God reveals His heart towards the "sojourner." In Deuteronomy 24 and Leviticus 19, God established a law to protect foreigners by allowing them to "glean" in the fields of landowners. Boaz demonstrates the grace of God by following this law, and seeking the welfare of Ruth.
Listen, as Pastor Kevin elaborates on the heart of God toward the outsider - and how this changes our hearts towards those who are "outcasts" in our midst.
