There was a time when I ate up Eldredge's writing, and indeed his style is still quite inspirational.
I think there are some very good things about this book, but there are also some things that are not so helpful, and plenty more that's really just fluff, mixes of pat evangelical rhetoric with metaphor and religious jargon. That's the real takeaway here, and probably the reason I burned out on this genre of Christian self-help long ago: it tries to say everything, but ends up saying even less than the secular psychology self-help stuff. If you came for theology, there's almost none. If you came for practicality, there's very little (the most "practical" attempt the book makes is writing prayers that you can pray, which can be good for those who have trouble forming such discourse...but even then, they aren't nearly as beautiful or deep as more traditional liturgical ones might be). If you came for psychology or therapy, there's a little bit here, but it seems watered down by the religious package it comes in. There's even a dearth of stories, which usually make these kinds of books both more tolerable and more immediately applicable.
A few good parts: he does a good job empathizing with the reader over how the pandemic (specifically) has affected our lives, attitudes, and outlook (generally), and most of what he has to say about that is helpful to identify. In fact, this is probably why I was able to finish the whole book: it felt good to keep reading. Certainly, even if we don't take a friend's advice in our tough times, it's a necessary part of our resilience to have an empathetic connection to one another.
He also brings in a few useful concepts from psychology, including one that will stick with me a bit: that of attachment. I'd never really seen attachment theory (he goes into depth on how mothers affect their children, for better or worse, from the very beginning) applied to faith matters, nor to stressors like the pandemic, but I thought he at least began a useful connection here. Certainly if faith is to be helpful and healthy for us in recovering from the trauma of the pandemic and the (less healthy) coping mechanisms we've triggered, relational therapy and concepts like attachment can be very actionable. Using maternal attachment analogously to our religious devotion offers a somewhat more mystical and emotionally complete way forward. Of course, he may have negated this later when he reverts to the basic evangelical line of "your feelings matter less than correct beliefs," which is only partly true, and often unhealthy.
I think his overall goal was noble: identify what we've been through in the pandemic, diagnose what it's done to our psyches and our relationships, and offer ways to heal. It delivers on 1, partially delivers on 2, and mostly fails 3.
If you're interested in the topic of resilience (or what some may call the "anti-fragility" of the human mind), I recommend the book "The Coddling of the American Mind," by Jonathan Haidt and Greg Lukianoff. While it was written before the pandemic (and I'd love to see an update of how that factors in), this book explores the concept of psychological resilience, and our postmodern cultural aversion to it, without needing to exist in a specific religious or political idiom. I've also heard that books like "Grit" and other educational psychology voices have been saying these things for years. Likely there will be more of these as we explore the affects of the pandemic in real recovery time.
Eldredge speaks to a narrow audience here, and will likely only connect to those who already agree with both his preassumptions and his methods for solutions. But if all he can really offer is "pray more," it's not going to go very far with readers outside that narrow Bible belt.
