Hebrews has long been called “the riddle of the New Testament.” In this episode of MARSCAST, Dr. Marcus Mininger returns with host Jared Luttjeboer to unpack why this mysterious book has both captivated and confused interpreters. Together they explore the famous warning passages, especially Hebrews 6, and ask what it really means that it’s “impossible to restore to repentance those who have fallen away.” Is the author teaching that some sins are beyond forgiveness? Or have we simply misunderstood his covenantal logic? Dr. Mininger offers a compelling framework for reading Hebrews on its own terms, revealing how its warnings flow from the story of redemption itself. If you’ve ever wrestled with the book of Hebrews, this conversation will challenge and clarify your understanding of its message.
