Do the book of Ruth represent a foreigner who saw the light?

Yes, the book of Ruth in the Bible tells the story of a Moabite woman named Ruth who becomes a follower of the God of Israel. Ruth's story is often seen as a representation of a foreigner who saw the light of God and chose to follow Him. Ruth's loyalty and faithfulness to her mother-in-law Naomi, as well as her willingness to embrace the God of Israel, are seen as examples of someone from outside the Israelite community who is welcomed into God's family.
