Pastorally edifying & personally encouraging
Format: Kindle
As a pastor and a biblical counselor, I’ve read Powlison many times. I know people who knew him personally. He is a man of nearly mythic proportions in the 2026 landscapes of biblical counseling.
And so, based the current landscape of the BC movement at the dawn of 2026, I thought it was to revisit Powlison myself.
This is an excellent little read. Recommended for ALL pastors and counselors.

Insightful, Bibical, and Helpful, but with One Major Oversimplification
Format: Paperback
This brief book posthumously publishes new reflections from David Powlison about pastoral counseling. The book opens with a foreword from Ed Welch, who writes about his personal connection with the author and the ways that this book has sharpened his thinking, and the main text includes an introduction, two chapters, and an appendix with suggested reading from both Christian and secular sources. Although "The Pastor as Counselor: The Call for Soul Care" is only eighty pages long, it is full of articulate, biblical, and concise reflections about what counseling is and why pastoral counseling is so uniquely powerful.
Insightful and Wise
Although I read this book from a layperson's perspective, I found it insightful and helpful. Powlison explains that pastors are always counselors, regardless whether or not they meet one-on-one with people, and show by example what kind of soul care they think is necessary for flourishing. He encourages pastors to take stock of how they present themselves and what common failings they need to avoid, such as offering platitudes or not listening well. He also delineates the clear differences between pastoral counseling and secular "therapeutic professionalism." He explains that because pastoral counseling is gospel-based and flows out of a personal relationship that is free from clinical detachment or professional reserve, it can be particularly powerful to help change people's lives.
One Concern
I absolutely agree with this, but unfortunately, Powlison creates a false dichotomy between biblical counseling and professional therapy, making it sound like all resources outside of the church will be unhelpful and spiritually destructive. The church has unique resources to meet sufferers' needs, and we shouldn't abandon Christians to the spiritually twisted and harmful ideas common within secular counseling, but Powlison creates a false dilemma between abandoning people to godless counseling versus taking on all of their care within the church directly. He does not address how Christian mental health professionals can support the church's work in complicated cases, and does not indicate what a pastor should do if someone's mental health situation or life struggles are beyond the church's understanding or ability to deal with.
Because I am not very familiar with Powlisons's work, I do not know what all of his views are related to integrative approaches to counseling, and it is possible that he has addressed this issue in-depth elsewhere. I certainly did not expect him to cover it in much detail in this very short book, but the oversimplification that he presents calls for discernment and additional reading. I hope that Powlison's writing here will not make pastors resistant to partnering with professionals outside of the church body, as long as those therapists bring a Christian worldview and gospel implications into each aspect of their work.
Conclusion
Despite my concerns about this oversimplified element, I would strongly recommend that pastors read this book as a way to evaluate themselves, better understand their unique role in people's lives, and consider how they can better care for others in their context. Powlison addresses many issues very well in this book, and it is a wonderful resource for pastors who need succinct, encouraging insight into how they can better understand the counseling aspect of their pastoral role and engage in meaningful conversations, caring relationships, and one-on-one care.

Truth will make you free
Format: Kindle
This book is simple, almost rudimentary in its approach to something we might take for granted. When we preach and teach because it is Sunday or Wednesday, we miss the greatest point of pulpit ministry. here are souls at sake and we are telling how to win the battle, not just another Bible story.

An essential resource for pastors
Format: Kindle
"The Pastor as Counselor" is an essential resource for pastors and church leaders navigating the intersection of faith, mental health, and soul care. David Powlison offers a wealth of Christ-centered motivational insights, practical guidelines, and biblical wisdom to encourage and equip pastors, leaders, and congregants in effectively counseling one another in the context of the church community.
“The Pastor as Counselor” includes two sections. The first section defines counseling, and the second lays out the uniqueness of pastoral counseling. One of the book's greatest strengths lies in Powlison’s unrelenting insistence that the pastor is a counselor and the conviction that counseling practices must be grounded in the teachings of the Bible. He notes that every place in Scripture that deals with specific concerns of individuals should be considered a counseling passage.

Excellent Short Treatise
Format: Kindle
This popped up in my feed as a recommendation, and I am very glad that I purchased it. Easily read in ninety minutes, but not shallow nor easily digested. I highlighted many passages in this book and will re-read in the future.
