What prominent Christians have said about our broadcast

Chris Arnzen is not afraid to deal with difficult issues or ask the hard questions. I appreciate the straightforward way IRON SHARPENS IRON tackles vital topics. It’s refreshing to hear a radio broadcast regularly deal with truly important, rather than trivial, matters.


Dr. John MacArthur

Author, Pastor, Radio Bible Teacher, Grace To You

I thank God for Chris Arnzen and his Christ-centered ministry with IRON SHARPENS IRON. Most grateful am I for his unwavering commitment to the absolute truth of Scripture. Here is a rare voice on the radio today. May the Lord set a wide and open door before this vibrant program for all to hear.

Dr. Steven J. Lawson

President and founder, OnePassion Ministries

It has been my joy to be interviewed by Chris on several occasions. Unlike some who simply want to have their own views validated, Chris is genuinely interested in biblical truth. He asks probing, weighty questions with the goal of equipping his listeners to be ready to give an answer for the hope that is within them (1 Peter 3:15). IRON SHARPENS IRON is truly an excellent name for this program. In a world in which many try to tickle the ears to appeal to the masses, Chris strives to rightly divide God’s word to feed the sheep. I am grateful for his program and enthusiastically commend it to you.

Justin Peters

Evangelist, author, teacher,

The subjects Chris Arnzen covers are not only relevant to the USA but also to the church on the African continent. He deals with those issues that are a menace to the church today and you cannot miss the fact that he wants those he is interviewing to base their answers squarely on the Bible. Keep it up, Chris; we need many people like you on this side of the Atlantic!

Dr. Conrad Mbewe

Author, Conference Speaker, Principal of Lusaka Ministerial College, Chancellor of the African Christian University, head of the African Renaissance University Project of the African Alliance of YMCAs, board member of Central Africa Baptist College & Covenant College Zambia, Pastor of, Kabwata Baptist Church, Zambia, Africa

What I appreciate most about Chris Arnzen is that he keeps the main thing the main thing. Chris’s unwavering focus on the sufficiency of Scripture to address social, cultural, and political issues facing the evangelical Church is refreshing to see in a time when even many who profess to believe in Christ are succumbing to the allurement of worldly ideologies and philosophies.

Darrell Bernard Harrison

author, conference speaker, co-host of the "Just Thinking" podcast, Dean of Social Media @ Grace To You, the Bible-teaching Ministry of John MacArthur

I had a fantastic time being on IRON SHARPENS IRON Radio! Very intelligent and thoughtful conversation, and we even had a few laughs! I had a genuine sense that we were discussing issues that are glorifying to God and help us grow in sanctification.

John L. Cooper

lead vocalist, bassist & songwriter/producer for 2-time Grammy Award-nominated 12x platinum band, SKILLET, & author of "Awake & Alive To Truth: Finding Truth in the Chaos of a Relativistic World"

I always look forward to being interviewed by Chris Arnzen. He knows what’s going on in the Christian world. He wades through the fluff and gets to the core issues. We need more Christian talk radio to follow the IRON SHARPENS IRON format. Substance with solutions to today’s muddled theological thinking. May its reach spread far and wide.

Gary Demar

American Vision

I’m so encouraged to know that programs like ‘IRON SHARPENS IRON’ are boldly defending the Bible from its very first verse. These are challenging times, and more than ever we need Christians in the media like Chris who will stand up for biblical truths without compromise.

Ken Ham

CEO/President, Answers in Genesis, Ark Encounter, and Creation Museum

Now more than ever, Christians need to stand firm on biblical authority and proclaim and defend the Gospel against all opposition. This is what Chris Arnzen does with IRON SHARPENS IRON. I am grateful to have been a guest on this program several times. Chris has given me the opportunity to share information that will encourage believers and challenge skeptics.

Dr. Jason Lisle

President and Founder of the Biblical Science Institute

I appreciate Chris Arnzen’s IRON SHARPENS IRON because Chris loves the truth. He is not afraid of where the truth will lead us or what it will demand of us and he is zealous to have the truth applied to the details of everyday life. If you’re interested in the truth, IRON SHARPENS IRON is worth your time and attention.

Paul David Tripp

Pastor and best-selling author

Chris Arnzen provides a packed hour of serious radio on Iron Sharpens Iron with meaty biblical and theological discussion which is a rarity in today’s world. Listen in. Stretch your mind. Learn the truth.

Dr. J. Ligon Duncan III

President, Alliance of Confessing Evangelicals

Chris Arnzen has his finger on the pulse of American culture and Christianity. His interviews are incisive and provocative. He brings Christian thought to bear on a host of contemporary issues that face twenty-first century Christians. Chris has the uncanny ability to get to the heart of a matter and to plumb the depths of what Scripture teaches on a particular issue. I most highly recommend Christians to listen to Chris’ broadcasts if they want to stay abreast of what is taking place in society and in the Church in our time.

Dr. Ron Gleason, Ph.D.

Pastor of Grace Presbyterian Church (P.C.A.), Yorba Linda, CA & author of The Death Penalty on Trial: Taking a Life for a Life Taken

Chris and I go back many years, discussing books along a broad spectrum of topics, whether biblical, ethical, social, and even law-related. One interview was on a matter of doctrine about which Chris and I have decidedly opposite views, giving proof-positive credence to ‘Iron Sharpening Iron.’ Despite whatever theological differences we have, our shared faith in Christ and passion for truth has been a blessing and encouragement even beyond the interviews, leading to a lasting personal friendship. The format of the program–unhurried, thoughtful, calm, and irenic–is uniquely suited to searching for truth. Where else can one find the luxury of explaining one’s thinking and writing without hype and ego getting in the way? And who else has such sheer, crazy fun in the midst of serious dialogue! It’s always a joy to spend time with Chris and his loyal listeners. Always an honor, my brother.

F. LaGard Smith

Compiler and narrator of The Daily Bible

It has been rare for me to hear God’s truth and Christ’s majesty referred to on the radio. But these sublime subjects I have now heard for the first time in a radio programme. Thanks be to God that Chris Arnzen opens a precious radio channel which tells the listening world what are the most important subjects of all. It was my very great privilege to speak about Christian godliness and spiritual conversation and to face splendid theological questions on this fine programme.

In this era of social media, the church desperately needs a sound voice. Chris Arnzen of IRON SHARPENS IRON Radio is that voice who uses his platform to pierce this present culture with the true Gospel. The exchange Chris creates with his guests will not only challenge your way of thinking, it will challenge your way of living!

Pete Orta

Thank you Chris for your kindness and tolerance in allowing me to present details of my exit from Seventh-day-Adventism. Thanks also for permitting me to give my views on a range of theological issues, and most of all on the Gospel of righteousness by faith. You are a gracious host and an incisive thinker. I greatly enjoyed the privilege of speaking with you!

IRON SHARPENS IRON is a good place to gather if you are among those who want real discussion of things that matter.

Doug Wilson

pastor at Christ Church in Moscow, Idaho, faculty member at New Saint Andrews College, author & speaker, founder of Canon Press, host of the "Applied Theology" podcast & blogger at "Blog & Mablog"

Chris Arnzen is an interview host without peer. He embodies the title of the program by being ‘sharp’. His rapier intellect cuts to the core of issues he discusses. It’s a delight for me to work with him!


Dr. R. C. Sproul

Founder & Chairman, Ligonier Ministries

If the rest of Christian radio would try to do what Chris Arnzen is doing with IRON SHARPENS IRON the body of Christ would be blessed and edified. As it stands, IRON SHARPENS IRON is unique.


Dr. James R. White

Pastor, Apologist, Founder & Chairman of, Alpha & Omega Ministries

Chris Arnzen is an exceptional interviewer with one primary objective–to know and make known the life, doctrine and ministry of the one being interviewed. He has a commanding personality and yet seems to disappear in the interview in order to give center stage to his subject. His questions were courteous, relevant and revealing. I knew that I was being interviewed by someone who studied my life and doctrine, and was interviewing me for the glory of God and the edification of God’s people.

Paul David Washer

founder, HeartCry Missionary Society

IRON SHARPENS IRON is one of the most bold and informative programs on Christian radio. The discussions are refreshingly candid and reliably profitable and Chris Arnzen is a superb interviewer with sound biblical instincts and a knack for asking the right questions. It is always an hour well spent.

Phil Johnson

Executive Director of Grace To You, the TV, radio & literary ministry of John MacArthur

Spending thirty minutes on air with Chris is like riding a bull in a rodeo without a clown to save you. Fast. Hard. Challenging. And somebody inevitably gets stepped on. It was a gas!

Todd Friel

Author, Host of, Wretched TV & Wretched Radio

Chris Arnzen represents a vital voice today. We are in a time that is growing ever darker. Furthermore, many Christian voices are capitulating to the culture on critically important issues.  Chris Arnzen and IRON SHARPENS IRON Radio are where the light of the Gospel and the sufficiency of scripture remain key.

Virgil Walker

author, conference speaker, co-host of the "Just Thinking" podcast, Executive Director of Operations @ G3 Ministries

While broad evangelicalism sleepwalks to Babylon, smugly embracing the culture that intends its demise, Chris Arnzen on IRON SHARPENS IRON exposes idols and exalts the word of God.

Dr. Rosaria Butterfield

Author, speaker, pastor's wife & homeschool mom

In a sea of distractions from the central message of Christianity, Chris Arnzen brings insight, joy, and biblical wisdom to bear on issues of interest to us all. Beyond informing, it will transform your thinking with the renewing power of God’s Word.


Dr. Michael Horton

Professor, Westminster Seminary California & host, The White Horse Inn

[Iron Sharpens Iron Radio is forever indebted to Pastor Ron Glass and the brothers and sisters of Wading River Baptist Church on Long Island, NY, for their unwavering encouragement and generous financial support, without which this program would likely not exist.]

In a day of shallow teaching and preaching across the spectrum of contemporary evangelicalism, Chris Arnzen’s “Iron Sharpens Iron” broadcast is more than a breath of fresh air. It’s an urgently needed source of information and interaction on the timeless theological and practical issues relating to biblical Christianity. Defying his critics, Chris has developed a format in which guests with high levels of expertise can discuss these important issues in far greater depth than the ordinary talk-show format permits, but do so in a way that is accessible to ordinary lay Christians. This is a program unique to the genre of Christian radio. Personally, I look forward to a time when “Iron Sharpens Iron” is widely syndicated both over the air and on the internet. Meanwhile, if you can, make this program a part of your daily routine. You’ll be a far more informed and equipped believer if you do!

Pastor Ron Glass

Former Adjunct Professor of Bible Exposition at Talbot School of Theology, & current pastor of, Wading River Baptist Church, Wading River, NY

Chris Arnzen is absolutely serious about making a real difference in the lives of his listeners with this radio show, bringing a serious word for serious believers.


Dr. Michael Brown

Apologist, Author & Host, The Line of Fire

Chris Arnzen’s IRON SHARPENS IRON combines astute cultural analysis with substantive theological understanding. It pairs a wide range of well-qualified guests with an articulate and gracious host. This is the best of compelling, relevant, and substantive Christian broadcasting. Listen in live. Listen in to the recording. Just be sure to listen in.

Dr. George Grant

Pastor of Parish Presbyterian Church (PCA), Founder of New College Franklin, President of the King’s Meadow Study Center & Founder of Franklin Classical School, in Franklin, TN, author of dozens of books & hundreds of essays, articles, & columns

I turn down interview requests from radio programs nearly every week. Most are looking for a sensationalized program full of juicy prosperity gospel gossip and idle chatter. Chris Arnzen is in a whole different category. He has a mind for God’s word and a heart for lost people. Chris is theologically sound, objective, and keeps the main thing the main thing. His love for the gospel, passion for truth, and desire to equip his listeners makes IRON SHARPENS IRON one of the most edifying programs on the air. It’s an honor to be a guest and a listener of IRON SHARPENS IRON Radio!

It’s a blessing to get to talk with Chris Arnzen. Glad he’s doing his part, connecting and filtering culture and politics through the Gospel to help preserve our republic.

Have you sat by the fireside with your favourite refreshment, coffee or tea and a shortbread cookie, and chatted to your best friend? Don’t you love those times when you share fellowship at a God-honouring, and joyful level, parting with prayer and with the warmest affection, feeling stronger in faith and thankful for those precious ties that bind us to fellow believers? Those are golden hours and anticipate what lies before us in the glory to come.

It is that ethos of holy affection that Chris Arnzen unconsciously, but by the Holy Spirit, seeks to attain and frequently achieves on his IRON SHARPENS IRON broadcasts. They attain that happy blend of discovering more of the truth of Christianity and a growing desire to walk more closely with God. We who participate in the programs look forward to them and are blessed to be taking part.

Geoff Thomas

Usually radio interviews are a thing one gets through with a sigh of relief but Chris Arnzen makes the experience more like a spirited discussion of important matters among friends that leaves you thinking. The gospel of Jesus Christ is front and centre and issues are addressed head on. It is a pleasure to know Chris and to have been a small part of this faithful radio ministry.

Jeff Kingswood

author, conference speaker, Banner of Truth Trustee, & Pastor of Grace Presbyterian Church (ARP), Woodstock, Ontario, Canada

Chris Arnzen asked good questions in a long-form show that allowed for full exploration of the themes within a new book of mine. He unabashedly showed Reformed understanding and practiced Brian Lamb interviewing: short questions without froth and suds so the guest has time to impress or depress.

Marvin Olasky

a veteran journalist, author of over twenty books, an elder in the Presbyterian Church in America, editor in chief of WORLD Magazine, & and dean of WORLD Journalism Institute

“In Chris Arnzen, host of IRON SHARPENS IRON Radio, the Lord has put together a great mixture of gifts. His theological acumen, network of relationships, radio experience, ready laugh, and love for God’s people shine forth on his program. The way he involves the audience in the live broadcast is masterful, making Iron Sharpens Iron unique and intriguing. A must-listen!”

“In a world filled with social media that is little more than fluff and hype, it is vital that we hear voices of substance and weighty reality: Chris Arnzen’s IRON SHARPENS IRON is such a voice. Great interviews and solidly biblical!”

— Dr. Michael A. G. Haykin, Professor of Church History & Biblical Spirituality, Southern Baptist Theological Seminary, Louisville, KY

“A good interview, in my judgment, demands questions that enable one to speak about various aspects of the Christian and Reformed gospel of salvation by the grace of God in Jesus Christ–its content and its history, as well as the calling of true churches and faithful witnesses in our day to contend for it. For such an interview, an interviewer is required who both knows the gospel of grace–its content, history, and present struggles–and loves this gospel of sovereign grace. The questions have to be knowing, pointed, and substantial. These demands are met by Chris Arnzen and the program, IRON SHARPENS IRON. I admit that until I became aware of Chris and his program, it never entered my mind that such a program and such a radio host existed, or could exist, in our godless and religiously bland age. And then with such a large, far-flung audience! Interviews are discussions about the word of God, including the history of its making its way in the world, with a fellow believer–an exacting, discerning fellow believer, but a friend in Christ Jesus. The main thing is that the word of God goes out into the world.”

— David J. Engelsma, Professor of Theology, Emeritus (Retired), Protestant Reformed Seminary, Grandville, MI

“What a joy to be interviewed by a consummate professional in Chris Arnzen! He is gifted at speaking the truth in love and addressing the hard issues of blending theology into everyday living in a culture that often opposes biblical truth.

“It was a joy to spend two hours on-air with Chris Arnzen. He clearly has the expertise and gifts that allowed for a relaxing, yet in-depth discussion about the pertinent issues of our day.

— Rev. Dr. Matthew Richard, Zion Lutheran Church, Gwinner, ND (LCMS), & author of “Will the Real Jesus Please Stand Up?: 12 False Christs”

“It was my privilege to once again be a part of the IRON SHARPENS IRON Radio program. As in times past, Chris was well prepared with questions to uncover the heart of the issue. We live in a day where men want to exalt error and destroy the truth. The time spent on IRON SHARPENS IRON was for the recovery of truth and the refutation of error. May the Lord continue to mightily bless Chris as he labors to exalt the name of Christ and extend His kingdom.”

— Dr. Mark Allison Pastor of Free Presbyterian Church of Malvern, PA, President of Geneva Reformed Seminary

“It is always such an encouragement and great blessing to experience and observe believers who are effectively using the various means of communication available to us today for the sake of the Kingdom as we reach out to those who have not yet come to Christ and encourage the Lord’s people in their walk with Christ. Chris Arnzen and the IRON SHARPENS IRON radio program is one of those blessings. It was my privilege to benefit from it and to participate in it.”

— Harry L. Reeder, III Sr. Pastor, Briarwood Presbyterian Church Birmingham, Alabama

Chris Arnzen is a superb host who does not fear to tackle the difficult issues of our day. This vital radio ministry has been raised ‘for such a time as this’ (Esther 4:14).”

— Dr. Tony Costa Author, Professor of Apologetics, Toronto Baptist Seminary

With great boldness and an unflinching commitment to the Bible, Chris deals with topics that are vitally important for the Christian community, especially in our day. Chris, thanks for all you do to keep us ‘sharp’ as the people of God. Your labor in the Lord is not in vain.”

— Michael J. Vlach, Ph.D. Professor of Theology, The Master’s Seminary Editor, The Master’s Seminary Journal

“Chris Arnzen is an experienced and competent interviewer. As a first-time radio ‘interviewee’ I was concerned about being able to fill two hours. Chris’ insightful questions and friendly interaction on air made the time fly by (as he said it would!) and made for a very enjoyable discussion! His relevant inquiries drew out the most important points that I wanted to make about the Amish. “

— Pastor Chuck Vuolo Reformed Baptist evangelist to the Amish community, Pastor of New Life Community Church, Kingsville, MD

“Chris Arnzen, host of the radio broadcast IRON SHARPENS IRON, is one of the few voices left in this post-modern era who will deal with a subject matter with the hopes of bringing correction and instruction to the lambs of the Lord Jesus. He doesn’t shy away from difficult topics, but tackles them head on. I really enjoyed our time together and look forward to the next time.”

— Dean Davis, author of “The High King of Heaven: Discovering the Master Keys to the Great End Time Debate”

— Mark Tooley, President of the Institute on Religion & Democracy, Washington, DC, author of “Taking Back the United Methodist Church”

— John Samson, Pastor of King’s Church, Peoria, AZ, author of “Twelve What Abouts: Answering Common Objections Concerning God’s Sovereignty in Election”

“Having hosted radio shows for a number of years, and having been interviewed on other shows many times, my time on IRON SHARPENS IRON with Chris Arnzen was a wonderful experience. Chris is an enthusiastic, passionate, and well-informed host. His interviewing style is engaging and provokes conversation, as opposed to just Q&A. My interview with Chris was easy–not because the questions were simplistic, but because Chris really knows how to shepherd a conversation. And what a blessing to be interviewed by a host as passionate about the subject matter as the guest! I hope the Lord allows me another opportunity in the future to be a guest on IRON SHARPENS IRON.”

— Tony Miano, Founder of Cross Encounters Ministries and Host of Soul Winner Radio

“Providence is a wonderful instructor, and a rich encourager. When paths cross with people of like mind we feel like long lost friends redeeming time together. Such it was as we conversed today on ‘Iron Sharpens Iron’ on a subject close to both our hearts, Jewish mission and Calvinism. Reformed mission to Israel is not an oxymoron; but rather biblically and historically, Jewish mission is an essential element of reformed theology. Thank you, Chris, for the opportunity to make a plea to my Calvinist friends not to neglect Jewish evangelism, and to my dispensationalist friends, to stop star gazing and start sharing Christ.”

— Stephen Atkinson, Asst Pastor Covenant Presbyterian Church, Fayetteville, AR Director of Ministry: Christian Witness to Israel (N America Inc.)

It was therefore a joyous contrast and an honour to be the guest on ‘IRON SHARPENS IRON’; a program that genuinely and fearlessly upholds and defends Christian truth. Chris Arnzen was both engaging in his manner and respectfully incisive in his questioning. Listener involvement was also stimulating and challenging and gave opportunity to exalt the wonderful Person and Work of the Lord Jesus Christ. ‘Iron Sharpens Iron’ – a beacon of light in a sea of darkness.”

— Cecil Andrews, Director, Take Heed Ministries

Chris has a deep interest in the church of Christ, its righteousness, and its grasp of biblical doctrine. The fellowship with Chris during ‘Iron sharpens Iron’ is a blessing for participants.”

— Walt Chantry, Author, evangelist, retired pastor, pioneer of the Reformed Baptist resurgence in mid-20th century America

Gary Habermas, Distinguished Research Professor Liberty University and Liberty Baptist Theological Seminary

The church needs a new reformation if it is going to impact the culture. Local radio is an important front in that effort.”

Chris Larson, Executive Vice President Ligonier Ministries

— Kim Riddlebarger, cohost of “The White Horse Inn”, senior pastor of Christ Reformed Church (URCNA), Anaheim, CA “IRON SHARPENS IRON is an invigorating and refreshing change of pace from what fills the airways of Christian broadcasting.

“Dear Chris– Thank you very much for the opportunity to be on your program. I thoroughly enjoyed my time.

“Chris Arnzen combines the depth of a well studied theologian and the lucid insights of an experienced journalist on his new radio program, IRON SHARPENS IRON. This is a very refreshing and much needed departure from the standard 22 minutes of preprogrammed info-sermons that usually is heard on most Christian radio stations. We can only hope that this is a taste of the future of Christian radio.” — Steve Camp, pastor, apologist and award winning Christian recording artist

“IRON SHARPENS IRON, artfully hosted by Chris Arnzen, provides a Christ-Centered forum for the honest and sensitive discussion of issues and topics of current interest to the Christian Community and beyond. My times as a guest on the program proved to be pleasant and profitable (albeit the topic was not without points of pain). Chris has a gracious facility for probing gently yet pointedly touching the tough as well as the tender spots. His range of topics span the spectrum from controversy to compassion and combine the “heart” concerns of spiritual pain and perplexity with the “head” issues of much-needed biblical and theological truth in a culture that seems to need a more clear direction with reference to God’s Word and God’s Will. May the Lord be pleased to prosper this Bible-based ministry.” — Ed Kuhlman author of An Overwhelming Interference

“Chris Arnzen is a well-informed host who does his homework and asks the kinds of questions that an interviewee wants to answer, and an audience wants to hear. Lively, collegial conversation and probing questions opened up opportunities for some really valuable exchanges of information and insights.” — Latayne C. Scott author of The Mormon Mirage

“IRON SHARPENS IRON is an exciting new Christian radio program that every believer should tune in.

“Those who turn to talk radio for substantive treatment of timely and timeless issues too frequently find a vast buffet of intellectual junk food; the experience is `as when an hungry man dreameth, and behold, he eateth; but he awaketh, and his soul is empty…’ (Isaiah 29:8).

As an old soldier for King Jesus of 81 years, being on his show was like being welcomed into the fortress of a fellow soldier and knight and slayer of dragons, who was as intent on advancing the territory of King Jesus on earth as I was. And though I never met him before, it was like we were old friends who had fought many bloody battles together on the battlefield and had the same scars from the swords of the same enemies. This man Chris Arnzen has been around and knows the battlefields and who are our friends and our enemies, and I found it very refreshing and encouraging to be on his show.” — Dr. Jay Grimstead, Founder & Director, Coalition on Revival

“IRON SHARPENS IRON is a dramatic and essential voice for the Christian home, church, and community. It is time to break out of the spiritual, social, and theological lethargy of the relatively safe and conservative experience of life in the last century. Chris and Pastor Buz create a lively and honest atmosphere for direct and incisive responses to the most painful and brutal life issues confronting Christians today. Christians must be as clever, creative, and unabashedly pointed about our nation’s (and the world’s) dilemma, its causes and the Gospel cure as the culture is in spewing out lies and wickedness. IRON SHARPENS IRON is doing that.” — Margy Tripp, Coauthor of “Instructing a Child’s Heart”, cofounder of Shepherding the Heart Ministries (, cofounder of Immanuel Christian School & counselor at Grace Fellowship Church in Hazel Township, PA

“Chris Arnzen of IRON SHARPENS IRON is my favorite radio host. He has the rare ability to bring the very best out of his guests by asking just the right questions and then getting out of the way. Too many radio hosts are constantly making sure you know how much they know. Chris seeks to display the knowledge of those he interviews and not himself. His humor adds to his program and his humility underlines all that he does.

Chris has the knack of leading his guests to talk about the sovereign grace of the Lord Jesus. Pietists, moralists and fundamentalists must be irked when they listen to Arnzen.

He asks the hard questions, but not to humiliate or to divide in this polarized age of ours, but to draw from his guests’ learning and experience that which benefits the worship, living, service, and witness of the body of Christ. In the process, his questions stimulate fresh thought and study; which all goes to say, to God’s glory, that iron truly does sharpen iron. May God long bless and widely use his discerning servant and his ministry of love in truth (2 John 1; 3 John 1).” — Dr. Tim J.R. Trumper (Ph.D., University of Edinburgh), Senior Minister, Seventh Reformed Church, Grand Rapids, Michigan

“Chris Arnzen was clearly engaged in this serious issue of the Church’s response to Coronavirus. His interview skills are excellent and his questions were right on target. So glad for a second interview opportunity as there is so much to discuss regarding what is contained in the book, as well as the spiritual environment to which this book has largely been targeted. The issues go way beyond just a virus, or just a mask, and Chris seems to have a clear grasp of the importance of getting this message out to the Christian Church.” — Ernie Springer, Dr. Joel Yeager & Dr. Dan O’Roark, authors of “CORONAVIRUS & THE LEADERSHIP OF THE CHRISTIAN CHURCH: A SACRED TRUST BROKEN”

IRON SHARPENS IRON unfortunately stands unique among radio talk shows in general and Christian radio in particular. With our culture rejecting the concept of truth and even the possibility of discussing competing positions of truth, Chris Arnzen stands as a beacon for all of radio in guiding discussions between the sylla of the banal “cult of personality” and Charybdis of the woke, “everything is offensive to me,” programs. Chris is focused, steady, committed to his view while being confident and gracious enough to allow those with whom he passionately disagrees to express theirs without devolving into ad hominem attacks, straw men assertions, or bombastic rhetoric in order to shut his guest down. I truly enjoyed our interaction though we might disagree on some matters of the faith. We laughed, shared personal encounters with our “heroes” of the faith, clarified some weighty theological and biblical issues for the listeners, and shared in true fellowship in Christ. I look forward to another possible opportunity to share air time with my brother in Christ, Chris. — Paul A. F. Castellano,
minister in the United Episcopal Church of North America & author of “As it is in Heaven: A Biblical, Historical & Theological Introduction to the Traditional Church & Her Worship”.

What does IRON SHARPENS IRON Radio mean? To me, IRON SHARPENS IRON Radio means CLARITY. The subject matter presented on IRON SHARPENS IRON Radio is direct, clear and relevant. This is personal to me in the area of Roman Catholicism. Several years back, Roman Catholic apologists were attempting to get me to convert to the Roman Catholic religion. Although I never bought into all of their arguments, I went through a very ‘confusing theological wilderness’ for about 2 years. After much prayer and study, God led me to the truth of the matter: The Roman Catholic religion was definitely not for me. Of the many resources and people that God used to lead me to the truth on this matter, I am happy to include IRON SHARPENS IRON Radio and Chris Arnzen. God used IRON SHARPENS IRON Radio to help bring clarity to me on this matter. — George C. Jensen, Lead Pastor at Enola First Church of God, Enola, PA

“Chris Arnzen is a good man with a godly mission! I was pumped to be a guest on Chris’s show and found our time discussing the Christian faith and ministry riveting.

Brandenburg, former Army officer & Pastor of Redeemer Orthodox Presbyterian Church of Carlisle, PA
