Is Truth Even Real Anymore? Why Everything Collapses If Truth Is Relative (Series: Faith That Can Answer Back, Episode 2)

We live in a moment where phrases like “live your truth” and “that’s true for you” have become common language. But what happens if truth itself becomes fluid?

In this episode of Reasonable Christianity, we step back from debates about religion and start with something even more foundational: truth itself.

Before asking whether Christianity is true…
Before discussing Scripture or the resurrection…
We have to ask a more basic question:

Does truth actually exist—and can we know it?

Drawing from classical philosophy and the work of Christian apologist Norman Geisler, this episode explores why truth is not a religious assumption but the foundation beneath every meaningful conversation. We examine why contradictions cannot both be true, why cultural relativism struggles to sustain itself, and why our deepest instincts about justice and morality quietly assume that truth is real.

If truth collapses, everything collapses—science, justice, history, even language itself. But if truth stands, then questions about God, reality, and the claims of Christianity become not only possible, but necessary.

This episode lays the groundwork for the rest of the series by asking a simple but unavoidable question:

Is truth something we create… or something we discover?

Because before we debate beliefs, we must settle whether truth itself stands.
