Two men who once rejected Christianity told a packed conference near Greensboro, North Carolina, that the very evidence they gathered to disprove the Resurrection ended up convincing them it was true.

J. Warner Wallace, a homicide detective who built his career solving decades-old murders, and Josh McDowell, who set out as a young atheist to dismantle the faith's central claim, spoke at a Truth for a New Generation conference organized by Alex McFarland. Hundreds of people attended. CBN News interviewed both men.

Their accounts share a striking thread: each applied adversarial scrutiny to the Resurrection and walked away a believer.

A Detective's Training Meets an Ancient Claim

Wallace didn't come to the question casually. He came with a skill set designed to determine whether dead people are actually dead, and whether witnesses are telling the truth.

"I'm going to have to figure out how to evaluate that for its truthfulness given this skill set that I had as a cold case detective."

His starting point was blunt. As a homicide detective, he said, he'd seen enough corpses to know what death looks like. He walked the audience through what professionals call the mortise triad: the biological markers that confirm a body has died and how long ago. CBN reported.

"That hot blood's going to stop circulating, you're going to cool down. That's called algor mortis."

Then rigor mortis: the stiffness that separates an unconscious person from a dead one. Then something more specific. Wallace pointed to the Gospel of John's description of blood and water flowing from Jesus' body after a Roman soldier drove a spear into his side. Water collects in the lungs after cardiac arrest, Wallace explained. Pierce the chest cavity, and you see a separation of blood and water.

"He was either so clever that he included some little-known biological fact that nobody would discover for 1800 years or he just reported what he saw. And as a result, we have a good piece of hidden science that confirms that Jesus actually died of cardiac arrest and was dead at the point of the body being taken off the cross."

That distinction matters because the "near-death escape" theory, the idea that Jesus merely fainted on the cross and later revived, has persisted for centuries. Wallace's forensic training led him to reject it outright.

Conspiracy, Hallucination, or Something Else

Wallace didn't stop at the death question. He turned to the witnesses. If the Resurrection didn't happen, the early disciples either conspired to fake it or hallucinated it. He applied the same framework he uses on cold cases.

Conspiracies, Wallace noted, collapse under pressure. They require tight relationships, limited participants, and short timeframes. The early Christian movement had none of those advantages. The Bible describes Christ appearing before 500 people. The disciples maintained their accounts for decades under persecution, imprisonment, and execution.

"So is it possible that they conspired for 60 years, at 500 plus people, under immense pressure, with not enough family relationships to hold it together?"

His answer was characteristically dry.

"Yeah, it's possible. It's just not reasonable."

He pointed out that no ancient record exists of any disciple recanting, even though forcing recantation was often the explicit goal of persecutors. On the hallucination theory, Wallace was equally dismissive, noting there is no documented history of group hallucinations with the kind of specific, consistent detail found in the Gospel accounts.

The Atheist Who Wrote the Book on Evidence

Josh McDowell's path ran parallel. As a young atheist, he set out to write Evidence That Demands a Verdict with the express purpose of proving the claims about Christ were, in his words, "Not True." He devoted dozens of pages to dismantling alternative theories. More than half a century later, he stood at the same conference explaining why every one of those theories broke apart under examination.

On the near-death theory, McDowell laid out the physical logistics. Jesus' body was wrapped in three separate linen cloths with roughly 117 pounds of aromatic spices and a gum of cement-like consistency that hardened around him.

"Christ was encased in that, and it becomes hardened. Second, how would He be able to move in such a state like that, a one-and-a-half to two-ton stone away from the entrance?"

On the stolen-body theory, he walked through the scene: as many as 16 soldiers guarding the tomb, a stone that contemporaries said 20 men couldn't move.

"The impossibility of that! That they could have climbed through there, tiptoed around all the guards, and became invisible to the guards in front of the tomb, rolled a one-and-a-half to two-ton stone that in that day that they said 20 men couldn't move it."

McDowell also cited two witnesses whose credibility is hard to dismiss precisely because they were hostile. The Apostle Paul, known as Saul of Tarsus, despised Christ as a false Messiah before his conversion. James, Jesus' own brother, was embarrassed by his sibling's public ministry. Both became leaders in the early church. Neither fits the profile of a gullible follower looking for a cause.

On hallucinations, McDowell said he interviewed five experts and reached a simple conclusion.

"No two people ever have the same hallucination because there's no external reference to it. It's all internal."

The Sunday Question

Conference organizer Alex McFarland raised a point that often gets overlooked in Resurrection debates: the behavioral evidence. First-century Jews staked their entire relationship with God on Sabbath observance. Breaking it could mean death. Yet the earliest Christians shifted their day of worship to Sunday, seemingly overnight.

"Pious Jews whose very relationship with God is contingent on keeping a Sabbath that they've observed for centuries, suddenly, overnight, begin to worship on Sunday. Why? Something must have happened. Well, Sunday was Resurrection day."

This is the kind of evidence that doesn't require a forensic lab. It requires asking a basic question: what event could compel devout people to abandon the practice that defined their faith? Something seismic had to drive that change. The early church's answer was consistent and unwavering.

Why This Still Matters

In an era that treats religious faith as quaint at best and dangerous at worst, something is bracing about two former skeptics standing before a crowd and making a case built on logic, forensic science, and historical documentation rather than sentiment. The cultural establishment treats belief as the absence of thinking. Wallace and McDowell represent the opposite: men who thought their way into faith by exhausting every alternative.

McDowell, more than fifty years into his own belief, told CBN News what the Resurrection means to him personally.

"It gives me hope that as Christ was raised from the dead, I shall be, too. Because of that,"

McFarland put the stakes in broader terms, arguing that a physical Resurrection validates everything Christ claimed: his identity, his message, his authority.

"In the empty tomb, we have it all, ironclad, guaranteed. I tell people the tomb was left empty so that your life could be made full."

The skeptics came with questions. They left with answers they didn't expect. And the tomb, as McFarland noted, remains empty.
