Chasing certainty is a losing game. Trust me, I’ve tried.

It feels noble, but it’ll smother your team, your relationships, your mission, and your peace, and it’ll leave you an anxious wreck.

And certainty and control are usually just more socially acceptable versions of anxiety anyway. But man, are they appealing to chase. Mostly because the world we now live in makes certainty feel attainable. And of course, AI makes the illusion of control easier than ever to believe.

So we tighten our grip on our people, on how we spend our money, on who we’ll trust, and on what we’re willing to believe.

But certainty is a dangerous illusion because knowledge will only lead you so far, and the need for control will smother any chance of organic development.

Here’s what I mean…

At the risk of offending you, let me get a little too personal on a topic that matters deeply to me. I asked Claude’s Fable 5 what the statistical likelihood is that the Bible is a factual historical document. For context, Fable 5 is one of Anthropic’s newest and most powerful models. It’s so powerful, the U.S. government shut it down for three weeks because they were afraid of the cybersecurity implications if someone found a jailbreak that could bypass its safety guardrails.

Anthropic describes Fable 5 like this:

“Fable 5’s capabilities exceed those of any model we’ve ever made generally available. It is state-of-the-art on nearly all tested benchmarks of AI capability, showing exceptional performance in software engineering, knowledge work, vision, scientific research, and many other areas.“

i.e., it’s pretty good at finding and knowing stuff.

We trust AI to help us make our most important decisions…parenting, relationships, mental health, large purchases, etc.

So I applied the same logic to faith…

Here’s what I told it:

“Based on everything you know about math, probabilities, statistics, etc. and based on all the data you have about the Bible, the historical evidence of the events in the Bible, the extra biblical historical documents, the way the Bible was handed down and transcribed over the centuries, etc., and the data you know about other historical events throughout history…what is the percentage likelihood that the Bible is a factual, historical document?”

In other words…

What’s the actual probability that the Bible is what it claims to be? Of course, it gave me a nuanced response, which I can respect.

The Bible is made up of thousands of claims spread across 66 books, multiple genres, and a few thousand years. So of course some of it is answerable with hard data and some of it isn’t. But I really wanted the cold, hard math on whether a rational human should trust the Bible…one of the most highly contentious topics in the world.

Here’s what it said:

First…

Was the text transmitted in a trustworthy manner over the centuries…beyond a shadow of a doubt? It was VERY comfortable giving me a resounding yes. It said there are over 5,800 Greek manuscripts of the New Testament alone, with fragments dated within decades of the originals, and nothing else in ancient history comes close to being as historically trustworthy. Even the skeptics agree we can reconstruct what was originally written with well over 99% confidence.

Okay, so the next consideration it walked through was…

Is the historical corroboration trustworthy (i.e., archaeology and extra-biblical sources)?

According to AI, the case for this is objectively crazy strong, too. For example, it specifically referenced the fact that the Pilate Stone, the Tel Dan Stele, Tacitus, Josephus, and Luke all name obscure officials by their correct titles in the correct cities. Luke’s precision has been verified again and again. Over the centuries since he wrote his Gospel and the book of Acts, historians and archaeologists have continually been catching up to him and proving him right.

Of course, the ability to “prove” the Bible is harder for the most ancient Old Testament books, because of course any 3,000+ year-old nomadic culture would leave thin evidence. Nevertheless, Claude’s most advanced model was comfortable putting an estimate of “comfortably over 90%” on the historical reliability of the Bible as a whole.

This was its exact response:

“The claim ‘the Bible is a reliably transmitted collection of documents, substantially rooted in real history, whose central events occurred in verifiable times and places involving verifiable people’ — I’d put that very high, comfortably above 90%, and higher than almost any comparable ancient corpus.”

But of course, there’s another caveat, which is at the core issue of faith… Faith is shaped by what you believe is possible before you ever look at the evidence. It’s a trust issue no matter how much you know. And this is the wall people hit.

A materialist and a theist can look at the exact same historical documentation of the empty tomb, the exact same early creed in 1 Corinthians 15, the exact same disciples dying for what they claimed to see, and land in different places. Which is why people are still broken and lost despite what stands as the most reliable historical accounts of a set of events ever. The evidence has long been strong enough to make belief in the Bible’s accounts intellectually respectable. But it’s not strong enough to remove the need for trust.

That gap is the entire point of faith.

No matter how much information you have, there’s always room for doubt.

But here’s the thing…

All relationships are built in that weird space between the knowable and unknowable.

Whether it’s God, your marriage, your parenting, your team, or your customers…the only place things grow is in the willingness to commit without having all the answers. It’s what you get in return for that release that builds trust. And trust is where the best things in life grow…love, joy, peace, patience, etc.

So if you find yourself anxious, it’s worth asking where your trust is. Have you been hurt enough to justify shutting down in the face of uncertainty? Because your need for control is probably smothering whatever it is you want to grow. Or are you willing to let go and trust?

Are you willing to release your grip on your team, your kids, your spouse, your perceived status, or the thing you’re not sure will work?

I think you’ll find that when you do, it produces a much better quality of life.
