In the event that a family member is depressed, and he doesn't feel bad enough already, recommend to him this book to add to his feelings of guilt and failure.
This book basically says that if you are a Christian (not if you're a non-Christian, mind you; non-Christians are pretty much written off as hopeless by the authors) you can CHOOSE not to be depressed, and if you ARE clinically depressed, well, it's because you're a self-absorbed sinner who is not choosing not to be.
"Happiness is a choice" the authors tell us some dozen or more times. Now, I certainly don't disagree that there is an element of choice in happiness, and that people can choose to dwell on their miseries rather than focusing on “whatsoever things are good,” but the authors take things far too far: “If any human chooses to live by these seven basic guidelines, we are convinced that he will go through life without ever suffering any of the pains of depression.”
I gave the book a whirl because it did have some good descriptions and lists. I was ready to stop reading when the authors set the timeline for grieving the loss of a loved one at 4-6 weeks, but I pressed on. Again, I almost stopped reading after this passage: "If a wife refuses her husband" [i.e. declines to have sex with him at any time, for any reason, other than if they are praying, the only biblical exception:] "she is violating his God-given right, and it would be appropriate for him to have some righteous indignation, as long as he forgives her by bedtime." Hey, doctors, don’t forget – ALL things are possible through Christ - even surviving without sex for a night or two with disappointment rather than indignation. Besides, isn't horniness, like happiness, a choice?
But I pressed on, skimming largely from this midpoint on, and there were a few helpful nuggets to be had, as well as a few necessary kicks in the pants. There was helpful chapter on how holding onto grudges breeds depression and the necessity of giving up grudges. On the whole, however, I would not suggest the book to a depressed friend or family member.
I will give this book some credit. Unlike most books on psychology or psychiatry, it will tell you that if you are living in sin (and I don't mean shacking up; I mean doing anything your conscience tells you is wrong), that may breed depression, and the best thing you can do for your psychological well being is stop and repent. It emphasizes the importance of the spiritual life in maintaining psychological health.
Note: If, like me, you take a somewhat pessimistic attitude toward this book, it's only because you're not choosing to be happy.
