Here are a few of the endorsements:
"This is a fascinating overview of the life and labors of one of the America's most gifted evangelical theologians. Drawing deeply from the wells of Reformation theology in the tradition of Calvin, Bunyan, Owen, Edwards, and Bavinck, Roger Nicole has set forth a compelling vision of theology as a discipline in the service of the church. And he has done so with grace, wit, insight, passion, and the kind of wisdom evangelicals need more of today. Though I never took a class with Roger Nicole, I am certainly one of his students and I commend this telling of his story to all who care about the Bible's God, the church's faith, and the world's need for the gospel of grace."
-Dr. Timothy George
"Here is a review of one of the most interesting Reformed theologians of the last seventy years. Roger Nicole's life has been spent in training ministers. Most of his students have known him only behind a lectern or in a brief meeting; here is much more of the story from WWI Germany to pre-War Paris, to Canada and beyond. Read and be encouraged to give your all in service to Christ."
- Pastor Mark Dever
"This is a moving tribute to one who has been valiant for the truthfulness of God's Word throughout his whole life. Not only is the measure of the man included, but amazing story here is the way Dr. Nicole's life has intersected with almost all the major events of the evangelical world in the past three-quarters of a century. It is a vivid reminder of the faithfulness of God and the bold necessity of ever speaking the truth in love both to those both who are part of the household of faith and those who are not."
- Dr. Walter C. Kaiser, Jr.
"Awesome for brain power, learning and wisdom, endlessly patient and courteous in his gentle geniality, and beloved by a multitude as pastor, mentor and friend, veteran Reformed theologian Roger Nicole comes beautifully to life in this warm-hearted biographical tribute. Thank you, David Bailey."
- Dr. James I. Packer
"The biography, based as it is on lengthy personal interviews with Dr. Nicole, has been both thoroughly researched and is well written. Between his Preface and Conclusion Bailey takes us in the eleven intervening chapters from Dr. Nicole's paternal grandfather's professorship in Greek language and literature at the University of Geneva and his father's pastoral ministry in Germany and Switzerland through his childhood and education and his teaching and pastoral ministry both in Europe and America up to the present. More, much more, could be written about this biography of Dr. Nicole's life and legacy but space constraints will not allow it. So I will close by stating unequivocally that anyone who takes the time and makes the effort to read it will be richly rewarded. He will be moved many times, as I was, both by Dr. Nicole's encyclopedic knowledge of the entire theological terrain and by his deep personal Christian humility. I can only hope and pray that through this biography more people will come to know and appreciate what a choice gift God has given to his church in the person of Roger Nicole."
