Andrew Root, professor of theology at Luther Seminary, offers a penetrating examination of evangelism amid the pressures and contradictions of modern life. In Evangelism in an Age of Despair, he argues that the church’s challenge is not simply the loss of belief but the progressive thinning of the soul shaped by cultural forces that promise happiness while producing exhaustion. Root extends themes developed across his earlier work, particularly the emotional fragility of the modern self, and places them in direct conversation with Christian witness. His book is not a manual of techniques; it is a theological retrieval grounded in the conviction that God himself moves toward human sorrow and that evangelism must be reordered around this pattern of divine descent.

Root’s opening diagnosis is one of the book’s strongest contributions. He characterizes late modern culture as an age of “happy misery,” where curated optimism masks deep interior depletion. Drawing on the long influence of Montaigne and the Western pursuit of self-curated happiness, Root argues that modern identity is relentlessly managed yet rarely healed (pp. 18–22). Evangelism shaped by therapeutic uplift, he warns, merely baptizes the cultural project rather than confronting its emptiness. In its place, Root draws attention to the apocalyptic presence of Christ, who “is found in sorrow” (p. 130). From this conviction emerges his central theological claim: evangelism is the church’s participation in God’s descent into human suffering.

At the center of this proposal is Root’s retrieval of a “theology of consolation,” shaped by Luther’s theologia crucis and informed by figures such as Gregory of Nyssa, Jean Gerson, Johann von Staupitz, and Blaise Pascal. These witnesses refuse the triumphalist instincts of the modern self. They draw attention instead to the places where weakness uncovers the movements of divine grace. Root distinguishes sharply between the modern self—curated, anxious, and fragile—and the soul—which is awakened through God’s gracious initiative. Evangelism, in this frame, is not the refinement of technique or persuasion. It is cruciform participation in God’s restorative presence, where life is brought forth from death.

The argument unfolds patiently. Root contends that the cultural shift from soul-formation to self-curation has left contemporary people profoundly alone. When churches adapt uncritically to these conditions, Christian witness is reduced to the marketable, the therapeutic, or the accommodating. Root applies steady theological pressure against these trends, calling Christian communities to cultivate spaces marked by patience and shared vulnerability. Such spaces, he suggests, make room for God’s consoling agency to be encountered rather than engineered.

Root writes with an eye towards those who carry unspoken exhaustion beneath outward competence, especially in contexts marked by pressure and performance. His reflections on the necessity of presence demonstrate a deep engagement with the emotional landscape of modern life. He recognizes that genuine evangelistic presence requires stamina and the willingness to accompany others without resorting to techniques that avoid the depth of their sorrow.

Root’s treatment of proclamation is enlightening. He does not sideline verbal witness; he reframes it within his theology of consolation. In Root’s vision, speech rises out of God’s own descent into human sorrow. Confession becomes the moment that the soul awakes to God’s nearness. As he puts it, “Soul comes through confession and surrender … the event of evangelism always calls for a confession” (p. 181). Proclamation, then, is never a tool to engineer outcomes. It is the kind of word that can only be spoken from within shared suffering. This shift reveals the heart of Root’s theological project: witness is truthful speech born from solidarity with the broken, not a strategy layered on top of it.

Not every reader, however, will find the book easy to navigate. Root engages with philosophical and historical sources in depth, which may stretch those less familiar with these conversations. His prose is reflective and occasionally dense, demanding careful and unhurried attention. He also threads a fictional storyline through the chapters. Some will appreciate how it illustrates the themes; others may find it interrupts the argument’s rhythm and slows its momentum. These stylistic choices undeniably shape the reading experience but do not obscure the project’s theological force.

Root’s doctrinal anthropology, though insightful, also invites further exploration. His distinction between self and soul provides a helpful lens for naming the pressures deforming modern identity, and his treatment of the “three malaises” (p. 62) exposes the fragility of the contemporary self with notable precision. Yet, the more contested dimensions of spiritual formation in a secular age, especially the role of eschatological hope and the future-oriented nature of Christian identity, remain less pronounced than his focus on divine descent and consolation. This creates a slight imbalance in a work otherwise attentive to the complexity of modern spiritual need.

Evangelism in an Age of Despair is a timely and serious work. Root directs the reader back to the cruciform center of the faith, where consolation, not happiness, becomes the ground of Christian witness. His theological vision is pastoral without slipping into sentimentality, and his account of evangelism challenges the church to imagine witness not as persuasion but as participation in the suffering love of Christ. For pastors, ministry leaders, and Christians navigating a culture marked by distraction, exhaustion, and unresolved longing, Root offers a compelling call to recover an evangelism rooted in presence and sustained by the God who meets his people in their sorrow.
