Every leader begins with enthusiasm, but only those formed by character can go the distance. In Endurance, Jeff Iorg turns to the New Testament and the history of the early church to show why perseverance is not optional for ministry leadership. This book is both biblical and practical, tracing how endurance is shaped in a leader's life and why it matters for long-term faithfulness. Along the way, Iorg offers a positive vision of ministry rooted not in talent or momentum, but in spiritual maturity, steadiness, and character that can bear weight over time. Written for younger leaders who want to build a lifetime of ministry, Endurance is a call to lead with durability, integrity, and hope. If the goal is to serve Christ for the long haul, endurance is not just helpful. It is essential.
