Three Worldview Questions We Cannot Ignore

There are three questions we need to address if we want to make sense of the world. These questions help us examine what we believe, why we believe it, and whether those beliefs actually matter. In this podcast episode, we explore how these questions expose assumptions that often go unchallenged.

A few months ago I had an interesting conversation with a friend of mine. I smiled and said, “How can you be thankful? You are an atheist!” He looked at me, slightly puzzled, and asked what I meant.

“Well,” I replied, “if there is no one to thank—how can you be thankful?”

He paused for a moment and then responded, “I can be thankful to the universe.”

“The universe?” I replied. “The universe can give a flying rip about you. It does not care about you or anyone.”

That conversation quickly became lively. What I was doing was not simply debating him. I was inviting him to question his own reasoning.

This is where an important insight becomes helpful. In his well-known book Tactics, Gregory Koukl, of Stand to Reason, explains that thoughtful questions are one of the most effective ways to engage people in meaningful conversations about their beliefs.

Koukl argues that there are two types of questions we can ask anyone.

The first is a definition question: What do you mean by that?

The second is an evidence question: What reason do you have for your position?

To these two questions I like to add a third.

The application question: What difference does it make?

Or, in teenage language: “So what?” or “Why should I care?”

These three questions help us move a conversation beyond slogans and into thoughtful reflection. They expose assumptions and force us to think carefully about what we actually believe.

In this podcast episode I share part of a lecture originally given at Trinity International University about engaging culture. As we interact with people in the wider world, we will inevitably encounter those who say, “No matter what you say to me, I will never change my mind.”

Even in those situations, our words may still matter.

You may not win the argument in the moment, but you can still leave a fragrance behind. At three in the morning, when someone is alone with the man in the mirror, your words may return to them and prick their heart.

Let’s hope it is a fragrance you leave behind—and not a stench.

A professor once said to his high school students, “Do you know what the two greatest problems of youth are?”

One student replied, “I don’t know and I don’t care!”

Exactly.

Ignorance and apathy.

These two attitudes continue to shape much of our culture today, which is why thoughtful questions are more important than ever.

Key Ideas in Brief

• Three questions help reveal the strength of any worldview. 
• Definition questions clarify what someone actually means. 
• Evidence questions examine the reasons behind a belief. 
• Application questions reveal whether a belief truly matters in real life. 
• Asking thoughtful questions opens doors for meaningful conversations about truth and faith.
  

Why Questions Matter in Worldview Conversations

Every person interprets the world through a set of assumptions. These assumptions influence how we understand truth, morality, purpose, and even our own identity. Yet many people rarely stop to examine the beliefs that shape their thinking.

Questions create an opportunity for reflection.

Instead of attacking someone’s beliefs directly, thoughtful questions invite them to explain their ideas more clearly. This often reveals hidden assumptions or contradictions that might otherwise remain unnoticed.

In many cases, a simple question can accomplish more than a long argument.

The First Question: What Do You Mean by That?

The first question is a definition question.

Whenever someone makes a claim about truth, morality, religion, or reality, it is important to ask what they actually mean by the words they are using. People often use the same words but mean very different things.

For example, someone might say they believe in Jesus. But before celebrating agreement, it is wise to ask what they mean by that statement.

Different religions and worldviews often define Jesus in radically different ways. Clarifying those definitions helps prevent people from talking past one another.

The Second Question: What Evidence Do You Have?

The second question examines the reasons behind a belief.

It asks a simple but powerful question: What evidence do you have for your position?

This question moves the conversation from opinions to reasons. Instead of merely stating beliefs, people are invited to explain why they hold them.

Sometimes people discover they have never really considered the evidence behind their assumptions.

That realization alone can open the door to deeper discussion.

The Third Question: What Difference Does It Make?

The third question explores the practical implications of a belief.

In everyday language, this question simply asks: So what?

If a worldview is true, it should shape the way we live. It should influence our decisions, our priorities, and our understanding of meaning and purpose.

When someone cannot explain how their beliefs affect their life, it often reveals that those beliefs may not be deeply rooted.

Truth, after all, is not merely theoretical. It has consequences.

Engaging a Culture That Doesn’t Care

Not everyone is eager to have these kinds of conversations.

Some people are openly hostile to discussions about faith. Others simply appear indifferent. They might say they do not care about religion, philosophy, or ultimate questions about life.

Indifference, however, does not mean someone lacks concerns or desires.

Every person has hopes, fears, relationships, and struggles. Those experiences often create natural openings for deeper conversations about meaning and truth.

Thoughtful questions can help uncover those openings.

Leaving a Fragrance Behind

Even when someone insists they will never change their mind, conversations can still matter.

Ideas have a way of lingering long after a discussion ends. A thoughtful question asked today may return to someone weeks or even years later when they are alone with their thoughts.

That is why the way we engage others matters so deeply.

When someone claims they will never change their mind, the goal is not necessarily to win an argument in the moment. The goal is to leave something behind—an idea, a question, or a moment of reflection that may resurface later.

Sometimes that moment comes in the quiet hours of the night, when a person is alone with the man in the mirror.

At that moment, a simple question may begin to do its work.

Will the memory of that conversation leave a fragrance behind, or will it leave a stench? The answer often depends on how we spoke, how we listened, and whether we treated the other person with patience and respect.

Questions, when used wisely, can open doors that arguments alone often cannot.

They clarify meaning, examine evidence, and reveal whether a belief truly matters in real life.

In a culture often marked by ignorance and apathy, thoughtful questions invite something different.

They invite people to think.

And sometimes, thinking carefully is the first step toward discovering truth.
