Evidence for Christianity: A Conversation with Gavin Ortlund

What if the toughest questions about faith actually lead us to the most compelling answers?

In this episode, we sit down with Gavin Ortlund, creator of the popular YouTube channel Truth Unites, to explore some of the biggest objections to Christianity—and discover why the Christian worldview not only holds up under scrutiny but offers profound hope for our deepest longings.

In This Conversation, We Explore:

• Does God Really Exist? We discuss the evidence from creation, the fine-tuning of the universe, and why the more science discovers, the more it points toward an intelligent Creator.

• The Problem of Suffering How do we reconcile a good God with the reality of evil and pain? Christianity offers a unique answer that no other worldview can match.

• Science vs. Faith Are they really in conflict? We unpack why this tension is often artificial and how both can coexist beautifully.

• Objective Truth in a Relativistic Culture In a world where "your truth is yours and mine is mine," what does it mean to claim that Jesus is the way, the truth, and the life?

• What About Those Who've Never Heard? One of the hardest questions believers face—and why we can trust God's justice while still feeling urgency about sharing the gospel.

• Why Christianity Is Such Good News The hope of resurrection and why, for believers, the best days are always ahead.
