I had the privilege of editing this book by a wonderful Christian woman, leader, and mentor, and I cannot recommend it highly enough. If, like me, you're always looking for a Bible study with some meat to it that goes deep into God's word and its application in our own lives, this is the Bible study for you. You might think, Well, Ruth is such a short book, how can there be much in it for me? Oh, beloved of God, this is the book for you! It digs so deeply into the culture of Ruth's time, the way Boaz's love for Ruth is a reflection of Christ's love for us, and how we can all have a Ruth-like attitude of trust and faith. This book is perfect for both group and individual study and even has separate, shorter lessons for those who have a set time period in which to finish it (such as a series of Bible classes). The book is available only in print, but it's definitely worth the purchase.
