Your kid just hit you with the question. Maybe at dinner. Maybe at bedtime. Maybe in the car on the way to school. And suddenly you’re standing there thinking, “I believe in God, but how do I actually explain why?”

Don’t panic. You don’t need a theology degree. Here are three concrete things you can say — and why they work.

Talking Point #1: “Everything That Starts Needs a Starter”

This is the simplest and most powerful place to begin. Ask your kid:

“Has anything ever just popped into existence from nothing? Like, has a toy ever appeared in your room with no one putting it there?”

They’ll say no. That’s because we all intuitively know that things that begin to exist have a cause. Scientists have discovered that the entire universe — all of space, time, and matter — had a beginning about 13.8 billion years ago in what’s called the Big Bang.

So if the universe began, what started it? Whatever caused the universe would have to be outside of space, time, and matter. That’s basically what we mean by God.

William Lane Craig has spent decades developing and defending this argument (called the Kalam Cosmological Argument), and even many atheist philosophers acknowledge it’s one of the strongest arguments for God’s existence.

What to say at the table: “Scientists discovered that the universe had a beginning. Everything that begins needs something to start it. So something outside the universe must have started it — and that’s what we call God.”

Talking Point #2: “The Universe Looks Designed — Because It Is”

This one is fun because it sounds like science fiction, but it’s real science.

The universe runs on physical laws and constants — like gravity, the speed of light, and the forces that hold atoms together. Scientists have discovered that if you changed any of these numbers by an incredibly tiny amount, life would be impossible. Not just human life — any life. No stars, no planets, no chemistry.

John Lennox, an Oxford mathematician, likes to use this analogy: imagine walking into a room and finding a radio perfectly tuned to your favorite station. You could say it happened by chance — but wouldn’t it make more sense that someone tuned it?

Lee Strobel, a former atheist journalist, investigated this evidence and concluded: “The fine-tuning of the universe is one of the most powerful arguments for the existence of a Creator.” The numbers are just too precise to be an accident.

What to say at the table: “The universe has these exact settings — like the strength of gravity — that have to be absolutely perfect for anything to exist. If you changed them even a tiny, tiny bit, there’d be no stars, no Earth, no us. It’s like someone set the dials just right.”

Talking Point #3: “We All Know Right from Wrong — But Why?”

This one connects to something your kid already experiences every day: fairness.

Kids have an almost volcanic sense of justice. “That’s not fair!” is one of the first moral statements any child makes. But here’s the question: if there’s no God, where does that sense of right and wrong come from?

If we’re just atoms and chemicals shaped by survival, there’s no real reason why kindness is “better” than cruelty — they’re just different survival strategies. But we know that’s not true. We know torturing someone for fun is genuinely wrong — not just unpopular.

Craig argues that the best explanation for this deep moral sense is that a moral God built it into us. We have a conscience because there’s a real standard of good — and that standard comes from someone.

What to say at the table: “You know how you feel it when something’s unfair? That sense of right and wrong — where does it come from? If there’s no God, it’s just chemicals in your brain. But it feels like more than that, right? That’s because God gave us the ability to know the difference between right and wrong.”

You Don’t Have to Have All the Answers

Here’s the most important thing: your kid isn’t looking for a perfect argument. They’re looking to see that you’ve thought about it. That your faith isn’t just something you inherited — it’s something you’ve wrestled with and found solid.

It’s completely okay to say, “That’s a great question. I don’t know everything, but here’s what I do know and why I believe it.” Honesty and humility are more convincing than a perfect lecture.

If you want to go deeper, three great books to have on your shelf:

• Lee Strobel, The Case for a Creator — investigative journalist style, very readable
• William Lane Craig, On Guard — clear, logical, accessible to non-philosophers
• John Lennox, Can Science Explain Everything? — short, brilliant, perfect for parents

Your kid asked because they trust you. That’s a gift. You’ve got this.
