This book was disappointing. I had hoped for an intelligent and considered discussion of sexuality from a Christian point of view.
What I got was a dogmatic and inflexible look at how not to do it. Such advice as "Don't spend time alone with someone you're dating, to avoid temptation". Apparently, dating couples should get better acquainted while involved in Christian work, missions and the like. Sadly, when they get married (on the advice of the book, which has a "Do it this way and you won't fail to get married" tone), they then get to talk to their new spouse. It'd be a shame if they then discovered a major incompatibility, which might otherwise have been discovered before the vows, but now it's too late. Given this advice, it seems somewhat illogical that the author then condones all divorces, what with him having provided advice on how to create one.
I advise you against buying this book.
