Query: Glean the Best and Toss the Rest

This book is a mixed bag. As you will see from some of the other reviews there are good points, but if you are in a difficult marriage, or just want to improve your marriage, you could find more help in books that focus on your love relationship with God, such as books by: Bob Sorge, or the book by Beth Moore "Praying God's Word - Breaking Free From Strongholds".
