In Spirit, Soul & Body, Andrew Wommack explains the tripartite nature of humans—spirit, soul, and body—and how understanding this is key to living a victorious Christian life. Wommack teaches that at salvation, the spirit is fully renewed and united with God (1 Corinthians 6:17), becoming perfect and righteous. However, the soul (mind, will, emotions) and body remain unchanged and need renewal through God’s Word (Romans 12:2). By focusing on the reborn spirit as the true self, believers can align their thoughts and actions with God’s truth, overcoming sin, doubt, and physical or emotional struggles. The book uses scripture to emphasize that this spiritual perspective unlocks healing, joy, and God’s promises. It’s written clearly for both new and mature Christians, aiming to transform how readers see themselves and their relationship with God.
