Dr. Roger L. Smith focuses on redefining the concept of sin, moving beyond a checklist mentality to its core essence. Dr. Smith emphasizes that sin is not just breaking God's rules but a deep-seated rebellion against His authority, a choice to amplify darkness and death over light and truth. Using the example of Adam and Eve, Dr. Smith highlights how rejecting God's word and relying on their own judgment led them to redefine reality and choose death. The core message is that sin is an internal corruption, a choice to live in an unreal world dictated by our flawed desires. Dr. Smith urges listeners to examine their lives, identify areas where they operate outside of faith, and choose to align their thoughts and actions with the truth of God's word to experience true life and freedom.
