12 Essential Questions Every Public Apologist Should Be Able to Answer

In this episode, Dr. Douglas Groothuis offers a passionate critique of the current state of online apologetics, prompted by the growing flood of YouTube, Instagram, and podcast-based apologetics influencers. While affirming the good work being done by some leaders, he cautions against the rise of shallow, flashy, and poorly studied content that too often passes for serious Christian defense.

Drawing from nearly 50 years of ministry, teaching, and academic publishing, Dr. Groothuis outlines 12 core competencies every public apologist must master — from a well-formed biblical worldview to knowledge of logic, philosophy, Scripture, world religions, and more. This episode is both a sobering warning and a visionary charge to anyone who desires to contend for the faith in today’s media-saturated culture.
