  • Amazing!

    I listen to this radio station regularly and absolutely love it. Chris Arnzen’s voice is not overbearing like some radio stations, but Chris’ voice is very easy to understand and the content on the radio station is 10 out of 10, I highly recommend you give 1 episode a go and you will be back for more great content in the future!

  • Excellent Program

    I may be biased because I have been interviewed by Chris before, but I was a long time listener before that. He is a great interviewer, and serves Christ. I really appreciate his conversation skills and am always left refreshed after I listen to one of his interviews. I’m grateful for his dedication and would highly recommend his podcast to Christians and Non-Christians alike.

  • Excellent! Addresses vital neglected subjects with faithful biblically-rooted guests!

    Highly recommended! Chris is a skilled broadcaster with deep biblical convictions. He is honest enough to admit without any shame or deception that he has these pre-commitments and convictions (unlike so many in the enemedia who claim to be merely impartial). Chris is fair-minded to guests who differ and allows guests (even those he may not totally agree with) to make their arguments clearly and at length. He also asks hard follow up questions and won’t let anyone get off the hook easily. This p... more

Talking Points

Recent interactions between the hosts and their guests.

Nov 2, 2026 Show with Ron DiGiacomo on “Attending a So-Called Same-Sex ‘Wedding’: Liberty or Disobedience?”
Q: If a Christian's job requires working as security, a police officer or an electrician at a same-sex wedding, should they go?
Arnzen and DiGiacomo say a person attending in a professional capacity is not necessarily acting as a celebrant or witness to the ceremony, and Boyle notes that each person should consider whether the work would violate their conscience.
Nov 2, 2026 Show with Ron DiGiacomo on “Attending a So-Called Same-Sex ‘Wedding’: Liberty or Disobedience?”
Q: Would you attend a Roman Catholic wedding, and if so, why condemn attending a same-sex wedding when you disagree with it?
Arnzen and DiGiacomo distinguish a man-and-woman marriage, which they regard as a creation ordinance even when held in a religious setting they reject, from a same-sex ceremony, which they view as celebrating a union contrary to biblical teaching. They also distinguish attendance from participating in religious rites such as receiving communion.
Nov 6, 2026 Show with Larry Herzog, Jr. on “One Man’s Journey Out from Freemasonry”
Q: What are the most compelling reasons people join Freemasonry, and are members expected to help fellow Masons even at great personal cost?
Herzog says members are expected to help a brother in distress when they can do so without a greater likelihood of losing their own life. Historically, fraternity, social connections and potential business advantages were draws, while curiosity also attracted some newer members.
Nov 6, 2026 Show with Larry Herzog, Jr. on “One Man’s Journey Out from Freemasonry”
Q: What were the issues with Freemasonry that caused you to leave, and how did your fellow Masons react?
Herzog cites prayers to a generic God, a works-based path to salvation, the use of the Bible as a prop, and religious rituals that he believes compete with the church and Christ. He says several members understood his reasons, some disagreed, and he faced no threats or major personal conflict.
Nov 5, 2026 Show with Joe Jacowitz on “True Worship in an Age of Counterfeits”
Q: How do you address those who interpret spirit in a way that implies charismatic type worship and manifestations?
Jacowitz distinguishes the Spirit's work in worship and the fruit of the Spirit from spiritual gifts exercised toward others. He describes worship in the Spirit as a vertical relationship with God cultivated through Christ, Scripture, prayer, fellowship, and other means of grace.
