Two excellent resources for marriage are:
1) Love and Respect by Dr. Emerson Eggerichs. If you don’t enjoy reading these kinds of things, I highly recommend the DVD series by that name. Ask for the conference DVDs. They’re very entertaining, as well as informative (he has a great sense of humor!). They are $105.95 with shipping (as of 2017). Call (616) 951-7300 eastern time to order.
2) Sacred Influence by Gary Thomas. This is an excellent book for helping wives to understand their husbands and become a positive influence in their lives. You may have to order it through a Christian bookstore, since it was published in 2006 and may not be in stock.
