In this moving and insightful memoir, a veteran firefighter recounts his struggle to navigate the difficulties of his dangerous job while standing firm in his Catholic faith. Here is not only a thrilling window into life as an emergency worker, but also a gripping tale of one’s man’s struggle to withstand the spiritual challenges of a secular workplace—a battle that will resonate with Catholics across the board. How is one to preserve one’s faith, and share it with others, in a society that has abandoned God? More concretely, what about vaccine mandates and rainbow flags?

With grace and humility, Benjamin O’Brien recounts how he navigated these questions and many more. Touching on mental health, bullying, self-control, courage, maturity, and conflict resolution, his story of daily life in the fire station and in the field, with all its graces and crosses, is a moving account of one’s man’s quest to be faithful in the midst of pain, fear, confusion, and sometimes intolerance. The reader is placed in the shoes of an ordinary man striving to make sense of life’s traumas and beauties, and to serve God in his daily work.

The Proving Grounds reveals how grace is always at work behind the scenes, purifying our understanding and motives and honing our character to greater maturity—sometimes in very surprising ways.

“A fascinating and inspiring insight into the dangerous world of a firefighter today. Here is a man of faith who must constantly choose to save life, to avoid sin, and to be true to himself as a son of God, no matter the cost. The Proving Grounds is a universal story that speaks to all of us.”
