Who Has the Burden of Proof?

Does the Christian have to prove God exists — or does the skeptic have to prove he does not?

How to use this guide

This guide is built for a 45-60 minute small-group conversation about "Who Has the Burden of Proof?." Open with prayer, read the framing aloud, and use the questions below to surface what people actually think before you walk through the case. Aim for honest engagement over consensus.

Facilitator tips

  • Read the lesson before the meeting; you do not need to be an expert, just a guide.
  • Resist the urge to fill silence. The best discussions follow long pauses.
  • When someone raises an objection you cannot answer, write it down and follow up next week.
  • Close with a single takeaway from each member, not a doctrinal summary.

What we're studying

Conversations collapse when both sides think the other owes the argument. Clarifying burden-of-proof keeps discussions productive and exposes rhetorical tricks like the "lack of belief" move — in which a skeptic makes positive claims while denying any duty to support them.

The case in brief

The burden of proof rests on whoever makes a positive claim. "God exists" and "God does not exist" are both positive claims, each carrying its own burden. The popular atheist move — "atheism is just a lack of belief, so I have no burden" — is either a retreat to agnosticism (in which case there is no disagreement) or a sleight of hand that smuggles a strong claim past the gate. A shared standard: whoever is asserting, owes reasons. This applies to both sides.

What if someone says...

Common objections and responses
Objection 1

"Atheism is the absence of theism, like baldness is the absence of hair."

Response

Then "atheists" and rocks and trees are all "atheists," which is absurd. The analogy works for the newborn but not for the philosopher asserting "there is no God."

Objection 2

"Extraordinary claims require extraordinary evidence — so the theist's burden is higher."

Response

"Extraordinary" is doing unspoken work here. Bayesian analysis handles this precisely: prior probability sets the bar, and strong evidence can clear it. The slogan without Bayesian machinery is usually a license to dismiss.

Discussion questions

  1. Have you ever accepted a claim without asking what evidence supports it?
  2. When you make a claim in conversation, what would be enough to get you to withdraw it?
  3. What is the difference between "I do not know" and "there is no God"?
  4. [Small group] Where in your own life does this question feel most pressing?
  5. [Small group] Who do you know that wrestles with this — and how could you talk with them about it this week?
