If there is one book I can recommend to an engage couple to read together, it would be The Meaning of Marriage by Tim Keller and his wife, Kathy. This book gives the readers what the Bible says about marriage which is appropriate for our day and time.
I am excited to announce that there is a Bible Study based on the Kellers' book. Here is the trailer for it:
Westminster Bookstore has a special going where you can get a Meaning of Marriage Bundle for only $50.00. In the bundle you get 2 copies of the book, 2 copies of the study guide, and a copy of the DVD. This deal is only good till October 15.
