I believe that the following books are 4 of the most essential books to having a healthy family and marriage. You can purchase any of these on Amazon. If you buy them used they are very inexpensive. Every couple that has children should have Boundaries with Kids. Every married couple should be given the gift of Boundaries in Marriage. Every family should collectively read The Bondage Breaker as it gives great insight as to how to avoid and overcome the demonic realm. If you don’t have these books, or your friends don’t, purchase them. They will change your life.
