A friend of mine is getting married after living with a man for a year. It is a second marriage for both of them. He is not a believer, and her actions speak against being one, too. They have requested any religious gifts be "minimal" at best. I would like to purchase a book on marriage from a Christian perspective because I believe it can be very beneficial in this world, and they will have a resource if they choose to use it. Two questions: Should I buy a book even though they have discouraged it? If yes, does anyone have any recommendations of a book with solid principles? Any insight is welcome!
