How we interpret "the god of this age" in 2 Corinthians 4:4 has significant implications for Bible translations, our doctrines of God and Satan, and missiology. Is this about God or Satan? Dr. Ivor Poobalan illuminates this unique Pauline phrase through his comprehensive examination of the history of interpretation and careful exegesis rooted in the historical and literary contexts. Entering into centuries of debate, this work challenges the two major pillars for the "Satan argument" - Apocalypticism and ancient Jewish views of Satan - to highlight the inconsistencies that make these foundations untenable. This insightful work brings a fresh voice that returns readers to an interpretation that "the god of this age" is the sovereign God responding to Jewish unbelief. For biblical scholars, translators, theologians, and pastors, Who Is "the God of This Age"? makes accessible previously difficult sources and opens up the implications of this interpretation.
