Arnold writes with a refreshing candor and forthrightness. Specifically, he can be downright blunt. Yet this always is shaped by a shepherd’s tough and tender love. …While I wish I had this book as a young man (or Arnold in person!), I’m glad I have it now. Arnold’s writing challenges and encourages young and old alike, beginners and leaders.

Bob Trube, Bob on Books

I have been very impressed with Arnold’s work, and find it thoroughly scriptural and very practical – right down my alley.

Elisabeth Elliot, speaker and author

I pray for all who read this book that they may come to follow Jesus more closely in their whole lives. He has not called us to be successful, but to be faithful.

Mother Teresa

Discipleship is a prophetic book in a time in which few people dare to speak unpopular but truly healing words.

Henri J. M. Nouwen, from the Foreword

I have found Discipleship to be an incisive and inspirational Christian guidebook. It is a clear call to higher religious ideals.

Jimmy Carter, Former President, Nobel Peace Prize Laureate

I have not experienced a book like this except when reading Dietrich Bonhoeffer and Christoph Blumhardt. Arnold sees beyond the present into the wonderful future of God’s kingdom.

Jürgen Moltmann, author, Theology of Hope

Discipleship helps us to understand what spiritual goodness is all about…It provides a mystic nurturing of the soul that translates into action that makes for justice.

Tony Campolo, author, Red Letter Christian
