Does truth actually exist? Can we know it? Or is everything just a matter of perspective?

Before anyone can meaningfully ask whether Christianity is true, we must first answer a more foundational question: What is truth?

This episode lays the philosophical foundation for the Christian faith by exploring the nature of truth itself. If truth does not exist, cannot be known, or is merely relative, then every worldview—including Christianity—collapses. But if truth exists and can be known, then we have a firm foundation for discovering what is actually true about God, reality, and ourselves.

In this episode, you'll discover:

• Does truth exist? Why every attempt to deny truth ultimately affirms it.
• What is truth? Why truth is best understood as that which corresponds to reality.
• Can truth be known? Why genuine knowledge of reality is possible.
• Is truth absolute? Why contradictory truth claims cannot all be true at the same time and in the same sense.
• How should Christians answer objections to truth? Practical responses to some of the most common challenges raised against objective truth.

The episode also examines and answers the major worldviews that challenge objective truth, including:

• Denialism — "Truth doesn't exist."
• Agnosticism — "Truth cannot be known."
• Skepticism — "We should doubt all truth claims."
• Postmodernism — "There is no objective truth."
• Relativism — "All truth is relative."
• Perspectivism — "Truth depends upon one's perspective."

Drawing from Scripture, philosophy, and careful logic, this episode demonstrates that these competing worldviews ultimately undermine themselves, while the biblical view of truth remains intellectually coherent and practically unavoidable.

If Christianity is true, then truth must first exist, be knowable, and be absolute. This episode begins building that foundation.
