Summary:
Having largely known Joshua Harris from his books on dating (and having not read them, largely due to the maddening pop culture surrounding his ideas), I dug into Dug Down Deep with some trepidation. I was surprised to find that Pastor Josh sheds off much of this “Christian-Dating-Guru” image and conveys a warm personality here with great theological depth in everyday language. I ended up buying several copies for friends who were struggling or new to Jesus.
Strengths:
As both an autobiography and a statement of Christian doctrines, somehow Dug Down Deep succeeds at both. Joshua Harris’ treatise on the Christian faith is a highly readable work that will stir both the young believer and the church veteran. We do not often stop to think on what we actually believe, and as Harris writes, what we think of God determines everything else: feelings, choices, character, our fate.
The personal touch here keeps the doctrine grounded. From stories of a wild youth group to Harris’ hippie father to Harris’ mentorship under C.J. Mahaney, the book is constantly engaging. It also paints theology as a captivating jewel to be cherished. Doctrine is not merely to be studied or weaponized, but is a life-giving truth that revives and rewires every part of us. There’s a deep humility in each page that cut through some of my “autopilot” attitudes. We may know much of what he writes already but hardly feel it because we have not thoroughly grounded our convictions. Harris’ journey may help you connect; it will surely remind you of the fascinating work and person of Jesus.
Weaknesses:
Some may find this book to be theologically “thin,” since Josh Harris does not present advanced doctrines like the End Times, predestination, ecclesiology, pneumatology, and the like. While I found that a good decision, others will disagree. The work also seems largely catered towards men, though women will find it a worthwhile read.
Bottom Line:
There has been some controversy as of late regarding Josh Harris’ senior pastor and his ministry, but this book reveals a sincere man who is neither perfect nor prideful. I have a newfound respect for him and do pray for him when I remember. Whether you’re a young or old Christian, Dug Down Deep will be a fresh breath of air for the doctrinally uninformed or the religiously exhausted. You will relate to at least one or two of his stories as well.
