How should Christians engage secular thought?

Honour image-bearers while making the gospel's claim clear.

THE STARTING ANSWER

Listen accurately and speak honestly. People outside the church remain image-bearers, with dignity and moral accountability, while sharing humanity's need for Christ. Secular humanism affirms ethics, reason and human flourishing without religious belief. We can recognise that stated concern without treating it as saving righteousness or accepting its account of reality.

  • Romans 3:9–24
  • R. C. SproulGod's image after the fall
  • Humanists InternationalDeclaration of Modern Humanism

FOLLOW THE REASONING

From the claim to the conclusion.

God's revelation in creation addresses everyone, and sinful humanity suppresses it.

  • Romans 1:18–23

Conscience bears witness to accountability beyond those who possess the written law.

  • Romans 2:14–16

The gospel calls all people to repentance and announces Christ's resurrection and coming judgment.

  • Acts 17:30–31

Christian witness joins respect for the person with a clear account of creation, sin, grace and the risen Christ.

  • Acts 17:24–31
  • 1 Peter 3:15–16

Do not mistake dignity for innocence

The continuing image of God explains why a non-Christian neighbour must be treated with honour. Common grace helps explain useful and kind conduct. Neither teaching cancels Paul's universal verdict of sin or the need for Christ's righteousness.

  • Romans 3:23–24

Let a position speak for itself

The Humanists International declaration is one organisation's account, not the creed of every nonreligious person. Use its sections on ethics, rational inquiry and fulfilment to identify actual claims; ask your neighbour which they share.

  • Proverbs 18:13

TAKE THE OBJECTION SERIOUSLY

Is religion necessary for someone to behave kindly?

Professed belief is not required for outward kindness. But no one lives independently of the God who gives life, and kindness does not justify a sinner. The deeper Christian claim concerns our dependence, guilt and need for grace.

  • Luke 6:32–33
  • Acts 17:25
  • Romans 3:20–24
  • Westminster16.7

Do not assume a person's whole philosophy from the label atheist, agnostic or humanist. Hearing their account first is a matter of truthfulness and neighbour-love.

  • Proverbs 18:13
  • James 1:19

CARRY IT INTO A CONVERSATION

How do you understand human dignity and moral responsibility, and where does your account place Jesus?

  • Acts 17:22–31
