“And you know that God anointed Jesus of Nazareth with the Holy Spirit and with power. Then Jesus went around doing good and healing all who were oppressed by the devil, for God was with him.” – Acts 10:38
Gustaf Wingren writes that when Jesus heals the sick and drives out evil spirits, Satan’s dominion is departing and God’s kingdom is coming. All Christ’s activity is a conflict with the Devil. God’s Son took flesh and became man that He might overthrow the power of the devil, and bring his works to nothing.
