Commendations
What prominent Christians have said about our broadcastChris 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.
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!
