In studying the Scriptures Dr Gooding says that our aim should be to find what it is that the Holy Spirit is teaching. When it comes to narrative books that relate a story, and somewhere along the line another story, it is not always easy to see any thought flow. To illustrate what he means, he uses the story of Ruth.
Naomi was emptied under the discipline of God; but far from that being the end of things, God had plans for her restoration and her filling. Ruth the Gentile proved to be the key, just as the Gentiles shall be the key to the final restoration of Israel, as Paul explains in Romans 11. Following the thought flow helps us to see God’s bigger picture.
