Nate faces an atheist geologist over ringwoodite’s potential flood waters and the biblical warning of a reprobate mind.

Has God Given You a Reprobate Mind? A Geologist Debates Ringwoodite & The Flood

What happens when an atheist geologist drops into the chat ready to talk deconstruction and ends up sparring over blue crystals that might hold oceans of water? Nate walks through the sobering reality of a reprobate mind while the conversation pivots to ringwoodite and whether Earth’s mantle could have supplied the water for a global Flood. From early calls about Jesus claiming deity to the final back-and-forth on peer-reviewed studies, the episode keeps one question front and center: has God given anyone over to a reprobate mind, and does the science of the deep Earth leave room for the Flood account?

Reprobate Mind: The Biblical Bottom Line

Romans 1:28 declares that when people refuse to retain God in their knowledge, He gives them over to a reprobate mind—a mind that is unapproved, corrupt, and no longer able to discern what is right. Nate presses the point that many “deconstruction” stories sound less like honest doubt and more like the process of searing the conscience. The Holy Spirit convicts; persistent resistance can produce the very peace that feels like freedom but matches the biblical description of being given over. A prophet cannot die for sins; only the perfect God-man can. Faith alone saves, yet the same faith produces good works as living water flows out of the one who has been born again.

Paul is not vague: the same chapter that describes the reprobate mind also shows the gospel as the only power that can reverse it. Readers who want the wider biblical conversation can also check the Christian Controversies section. As GotQuestions summarizes, a truly regenerated believer does not remain in that state; the old has passed away.

Blue Crystals, Mantle Water, and a Geologist’s Pushback

The guest, a working geologist, admits he has never heard the ringwoodite argument before. Nate lays out the claim: this high-pressure mineral found in diamonds from hundreds of kilometers down can store hydroxide equivalent to one-to-three times the water in Earth’s surface oceans. If a mechanism existed to release it, the volume would more than cover the highest peaks. The geologist counters that the energy released during expansion could vaporize the planet and that current estimates of total ringwoodite remain too uncertain to settle the question. Nate is clear: the mineral does not “prove” the Flood, but it undercuts the confident claim that “there simply is not enough water.” The exchange ends with both sides agreeing more conversation is welcome—preferably with the actual peer-reviewed papers open on the table.
