Last August 2025, about 6 months ago as of this writing, Ben Kayser started a website and Youtube channel called “Reformed and Dangerous.” From his ‘About’ he stated, “AI-powered songs and rap battles where Scripture meets swagger. Watch pastors, theologians, and historical figures face off in lyrical showdowns on Calvinism, theonomy, church history, and the gospel.”
Recently Kayser put up a ‘rap battle’ between John MacArthur and RC Sproul. He creates AI (artificial intelligence) videos of the theologians saying the lines. These ‘rap battles’ never happened in real life. They are all virtual, thanks to AI.
John MacArthur was a well known and widely loved pastor of Grace Community Church for 56 years. He passed into glory 7 months ago. RC Sproul was pastor of St. Andrews Chapel and founder and chairman of Ligonier Ministries. He passed into glory 9 years ago. The two men were good friends, despite their different theological interpretations of eschatology and baptism.
After MacArthur’s passing a few months ago, almost immediately there was an influx of AI generated videos of a virtually created MacArthur preaching. Some of the videos stuck close to his years-long stated doctrinal interpretations. Others took liberties and put words in the artificial MacArthur’s mouth he never said or believed.
This was a problem. MacArthur’s close friend and manager of MacArthur’s digital recordings at GTY.org, Phil Johnson, put out a warning to the public regarding these AI videos, writing at ,
“YouTube is overrun with videos purporting to be John MacArthur—but produced by AI. These do not reliably represent John MacArthur’s opinion. The only way to be certain any recording is legitimately John MacArthur’s is to get it from http://gty.org. “
So enter in ‘Reformed and Dangerous’ rap battle AI generated video. In the Youtuber’s mind, I’m sure there was no malicious intent. It was just another of his hugely popular videos, and instead of creating videos of long passed theologians John Calvin or Charles Spurgeon, this time Sproul and the newly passed MacArthur were featured.
His video caught the attention of GTY Director Phil Johnson. Apparently in the background, Phil had asked the Reformed and Dangerous publisher to remove the video. R&D did so. Kayser put out an explanation for the public as to why he took it down, right-click on the link in the embed to go to Twitter/X. You can also read the read his explanation on Facebook here.
Phil wrote an essay about the issue. He said that prior to MacArthur’s death, the elders and he had a discussion about AI. Johnson said,
“John was never a fan of Siri or Alexa, and he certainly did not want to lend his face, voice, or personality to an AI-generated cyber-pastor or digital rabbi.” … Johnson is not in favor of AI generated rap battles “because doing something in John MacArthur’s name that we know with absolute certainty he would disapprove is no way to honor him.“
Phil’s essay is here at his Pyromaniacs blog.
VIrtual reality is interesting to me. First, as Christians we need to be as Matthew 10:16 says, “Behold, I am sending you out as sheep in the midst of wolves; so be as wary as serpents, and as innocent as doves.” We cannot be gullible. We must determine what is real and what is virtual. Scam phone calls, fake videos (and Youtube is overrun with them), fake news, and more plague our lives these days. This is one of the downsides of technology, which otherwise has many great advantages.
Second, virtual reality on earth is like earth’s life being virtual as heaven’s life is real. We Christians are sort of living in a virtual reality while the actual reality is heaven. Earthly life is not meaningless, to be sure. It is preparation for heaven. But earth’s life is as virtual as AI compared to heaven. A pale copy! Dear reader, always remember our citizenship is in heaven. Our real life begins the moment we are translated to heaven and we see Jesus face to face.
Meanwhile on earth, as sin grows, fakery grows. Liars, cheaters, deceivers abound. Watch where you step.
