Challenging Injustice with Faith: A Courageous Conversation on Morality and Equity

Challenging Injustice with Faith: A Courageous Conversation on Morality and Equity
Is It Just? Reclaim the Vision of Justice Through the Lens of Jeremiah — 5-Day Ebook Promo: Get It for $0.99 (August 1–7, 2025)

With injustice dominating headlines and division fracturing communities, many believers are asking: Where is God in all of this? In his powerful new book, Is It Just? A Thematic Study of the Book of Jeremiah, Bible teacher Trevor Whitman issues a sobering but hopeful challenge to the Church: return to the heart of God—a God who demands justice, calls for repentance, and invites us into His redemptive presence right now.

Is It Just? is a compelling, accessible, and convicting thematic guide through one of Scripture’s most misunderstood prophetic books. More than a Bible study, it’s a call to inventory our lives and communities, asking: Are we aligned with God’s justice—or merely playing religion while neglecting the most vulnerable among us?

“If your Christianity only looks forward to heaven and ignores the injustice in front of you, it isn’t biblical Christianity.” —Trevor Whitman

What You Will Discover in Is It Just?

  • A fresh, thematic overview of the book of Jeremiah that doesn’t compromise depth or context.
  • Clear guidance on how ancient prophetic warnings speak directly to today’s church and society.
  • An exploration of key themes: justice, idolatry, repentance, self-sufficiency, and God’s enduring faithfulness.
  • Insightful discussion questions at the end of each chapter, perfect for groups or personal study.
  • A sharp challenge: Stop idolizing comfort, start embodying compassion.
