Not For This Life Only: A Study for Growth Into Maturity as a Child of God - for Today and for Eternity by Irvin Stapf is a well-written and inspiring book. Pastor Stapf's emphasis is on aligning with God's blueprint to nurture our spiritual journey for His realm. Life encompasses much more beyond mere acceptance of divine pardon. It entails embracing faith in God and adhering to a developmental roadmap. This pathway gets us ready for the magnitude and beauty that is Heaven. An interesting read and for those of faith, an important one.

Rev. Irvin Stapf masterfully describes one of the more important purposes for our life here on earth in his excellent book "Not For This Life Only". I don't want to give too much away here in the review, but a core premise found throughout the book is God's plan to help us grow in "agape love" using Christ's life and His sacrificial love as an example. All this is in preparation for our time living eternally in God's Kingdom. Pastor Stapf does an excellent job of using core Biblical principles, and does not stray from them. For example, he makes it clear that we are only able to exhibit this agape love, because of the Holy Spirit living within us, and that we can take no credit for this spiritual growth throughout our lifetime in preparation for the afterlife.

This book is filled with so much wisdom that I originally bought the eBook version, but then I also purchased a paperback version for my bookshelf and to share (although I encourage others to buy their own copy given the reasonable price). I've read the book once, but plan to re-read it slowly and digest it in smaller pieces in order to fully absorb its content. What is really impressive is that despite the scholarship and interesting ideas presented in this book, Rev. Stapf humbly gives credit to God and generously mentions several sources in the book's bibliography.

According to the back cover of the book, the author is a Lutheran pastor, and he does adhere strictly to Lutheran doctrine based solely on the Bible. However, this book should appeal to a very broad Christian (and hopefully non-Christian) audience. Everything covered in this book is "Biblically-backed", so all Christians should enjoy and agree with its content. It is simple and straightforward enough for the "young/beginning" Christian to understand. But, it also has enough "meat" to be enjoyed, read, and re-read by more mature believers.

Congratulations to Rev. Stapf for authoring an excellent book.

Letters from The Elder to a World in Confusion by Irvin Stapf is a deeply thought-provoking and spiritually urgent book that seeks to address one of the most pressing issues of our time: the reality of spiritual warfare in a confused, divided, and fast-paced world. Structured as a series of 19 letters, the book draws readers into a reflective dialogue with “The Elder,” a voice of wisdom that calls believers to reassess the foundations of their faith and their place in God’s original design for humanity. The epistolary style adds a sense of intimacy, as if the reader is personally receiving counsel and exhortation for navigating modern struggles.

Stapf does not shy away from difficult truths. He openly admits that some readers may feel uncomfortable with his message, but this honesty is part of the book’s strength. Rather than offering shallow comforts or platitudes, the author confronts the harsh realities of a world where advanced technology, cultural shifts, and moral relativism have distracted us from the two greatest commandments: to love God and to love our neighbor. By framing these issues within the context of spiritual warfare, Stapf underscores that the battle is not simply cultural or political—it is profoundly spiritual.

One of the standout features of the book is its ability to balance urgency with hope. While Stapf highlights the destructive influence of satanic forces and the ways society has strayed from God’s plan, he continually points readers back to the redeeming power of Jesus Christ. This dual emphasis—recognizing the reality of the battle while affirming the certainty of victory in Christ—makes the book both sobering and encouraging. Readers are reminded that God’s joy, peace, and strength are far greater than any counterfeit promises offered by the world.

The letters themselves are versatile in scope, touching on everyday concerns as well as larger cultural trends. Topics range from the temptations of materialism and the false allure of technology to the timeless call for deeper fellowship with Christ. Each letter is grounded in Scripture and practical reflection, making the work accessible to both new believers and seasoned Christians seeking renewal in their faith. Stapf’s writing is pastoral, direct, and heartfelt—he writes not to impress but to shepherd souls.

What sets Letters from The Elder to a World in Confusion apart is its prophetic edge. It is not merely a devotional or theological treatise; it is a wake-up call. Stapf challenges his readers to stand firm, to resist compromise, and to recognize the spiritual forces at work behind the confusion of modern life. His words resonate with the urgency of someone who sees the stakes clearly and cannot remain silent. For readers tired of superficial answers, this book provides a refreshing depth and seriousness that is often missing in contemporary Christian literature.

Ultimately, this book is a guide for those who feel disoriented in a culture of noise and deception. It reorients the reader to the eternal truth of God’s Word and the simple but radical call of discipleship: to love God fully and to love others sacrificially. Irvin Stapf’s Letters from The Elder to a World in Confusion is not an easy read in the sense of comfort—it is an easy read in clarity, but it is challenging in its implications. And that is precisely why it is a book worth reading, sharing, and discussing.
