Irvin Stapf’s Not For This Life Only is a heartfelt and theologically rich exploration of Christian spiritual maturity. Framed as a devotional guide, the book challenges readers to see life not as an end in itself, but as a preparation for eternity. Drawing from Scripture, personal anecdotes, and traditional Christian teachings, Stapf argues that our time on Earth is an “apprenticeship for rulership” — a training ground for the eternal responsibilities and relationships we’ll carry into God’s Kingdom. He stresses the need for Christ-centered values, patient endurance, and above all, the development of agape love, the kind of selfless love God shows us and asks us to reflect.

I found the sincerity of Stapf’s writing both moving and compelling. There’s an honesty in the way he addresses life’s harsh realities — suffering, injustice, disappointment — and how they are not only unavoidable but essential to Christian growth. His style is warm but firm, often sounding like a wise, steadfast pastor speaking to someone he truly cares about. When he tackles moral relativism, the decay of modern values, or the compromises of the Church, he does it with conviction, not arrogance. He invites repentance, not condemnation. The writing may not be flashy or literary, but it’s soaked in conviction.

The book returns often to key themes — like obedience, spiritual warfare, and the training of the soul — and while these ideas come up repeatedly, the repetition feels purposeful. It’s as if Stapf, like a seasoned teacher, knows how important these truths are and how easily we let them slip from view. His steady reminders help anchor the reader, reinforcing the message in a way that builds depth and clarity over time.

I would recommend Not For This Life Only to believers who are hungry for more than just spiritual comfort. This book is for people who want to grow, who are willing to wrestle with themselves and their faith, and who know deep down that easy answers just won’t cut it. If you’re looking for a soft, feel-good devotional, this isn’t it. But if you’re ready to be challenged, encouraged, and maybe even humbled, then pull up a chair. Stapf has something worth reading.
