Christ’s death on the cross rendered a definitive judgment against both Satan and the sin nature. Satan’s condemnation is settled, though the execution of that sentence awaits his future confinement and final destruction. Likewise, the sin nature was judicially crucified with Christ, nullifying its authority even though its presence and impulses continue within every believer. God has created a new nature that delights in Him, and the Christian life unfolds amid the ongoing conflict between flesh and Spirit. Victory comes through learning and applying God’s Word, walking by faith, and living under the Spirit’s empowering ministry.
