The Book of Ruth should be read when you read the Book of Judges. The biggest advantage is realizing that among the blood lust of Judges there is a beautiful story of redemption.
Reading Judges will be a tough read. Realize it’s not about the book telling us what is “right.” It is giving us a story of what is desperately wrong.
But read Ruth and be refreshed in the story of redemption among the rubbish heap of degradation.
