What Is “Vibe Coding”? A Christian’s Honest Introduction to Building Software with AI

Let’s get the awkward part out of the way first: yes, “vibe coding” sounds dumb. It sounds like something a Bay Area founder said at a party at 1 a.m. and somehow it stuck. The truth is that’s pretty close to what happened.

The term comes from a 2025 tweet by Andrej Karpathy, one of the most respected AI researchers in the world. He described a workflow where he’d “just give in to the vibes, embrace exponentials, and forget that the code even exists.” He was describing what it feels like to build software when AI is doing most of the typing.

That’s vibe coding. It’s not a joke and it’s not a fad. It’s the most important shift in how software gets built since the iPhone.

So what does it actually mean?

Vibe coding is the practice of building real software by collaborating with an AI like Claude in plain English. You describe what you want. Claude writes the code. You guide the process — pushing back, refining, asking questions, testing. The AI does the typing. You do the thinking.

It’s not no-code. No-code tools (like Squarespace or Bubble) give you a fixed set of building blocks and you arrange them. Vibe coding gives you a fluent collaborator who can build literally anything you can describe.

It’s also not the “AI replaces programmers” story you’ve been hearing for two years. Programmers are some of the people who benefit most from this. But the bigger story is what happens when 100 million people who never could build software suddenly can.

Why it matters for Christians

Here’s the part that actually matters. For most of human history, “people who could turn an idea into a piece of working software” was a small, expensive priesthood. Want to build an app that helps people read the Bible in a new language? You’d need $200,000, a year, and a development team.

Want to launch a Christian small business? You’d need a designer, a developer, a hosting expert, and a marketer.

That moat just collapsed. Almost overnight. And it collapsed at exactly the moment when the church needs more builders, not fewer.

Three things vibe coding is great at right now

1. Shipping a real website in an afternoon. Not a template. Not a Squarespace page. Real, fast, custom code.
2. Building small tools for your family, ministry, or business. Things you’d never bother to hire someone for, but which would actually change how you work.
3. Launching your first online business. The first real test of vibe coding for most people is something that takes a credit card. And it works.

The honest catch

Vibe coding still requires you to think clearly. Claude is the most patient, brilliant, never-tired collaborator you’ll ever work with — but it can’t want anything for you. It can’t decide what to build. It can’t tell you who you’re building it for. It can’t care.

That’s your job. The good news is that’s the part Christians have always been pretty good at: knowing what matters, and being willing to do the work in front of them.

The other catch: if you treat Claude like a magic wand and don’t learn anything yourself, you’ll get stuck the first time something goes wrong. The people who do this well treat Claude like the best junior teammate they’ve ever had — they learn alongside it, and they get better every project.

Where to start

If this is the first time you’re hearing about any of this, here’s what we’d do in your shoes:

• Read our post on installing Claude Code (it’s easier than you think)
• Pick a tiny project — not the big idea you’ve had for two years, but the “wouldn’t it be cool if” one
• Spend three focused hours with Claude and see what you ship

That’s how every single one of our students started. None of them regret it.
