Defending Truth in a Post-Truth Age
Featuring Dr. Douglas Groothuis
May 26, 2026
Dr. Doug Groothuis, Cornerstone University’s first distinguished professor for apologetics and Christian worldview, joins host Gerson Moreno-Riaño on the Wisdom and Influence podcast to discuss the defense of objective truth in an era of cultural and theological compromise. Groothuis traces the concern behind his landmark book Truth Decay and its forthcoming sequel Taking Back Truth, examining how postmodern philosophy has eroded confidence in Scripture, sexual ethics, and the exclusivity of the gospel. The conversation also addresses the dangers of syncretism with Eastern religions, the false dichotomy between rationality and wonder in the Christian faith, and Groothuis’s upcoming book What If Jesus Is Right?, co-authored with Lindsay Medenwaldt, which presents the case for the deity and lordship of Christ to thoughtful seekers. Listeners will gain a deeper understanding of why a Christian worldview grounded in sola Scriptura is essential for education, cultural engagement, and faithful living.
