You know of Jesus of Nazareth, how God anointed Him with the Holy Spirit and with power, and how He went about doing good and healing all who were oppressed by the devil, for God was with Him.
While Peter was still speaking these words, the Holy Spirit fell upon all those who were listening to the message. All the circumcised believers who came with Peter were amazed, because the gift of the Holy Spirit had been poured out on the Gentiles also.
Evil spirits not only exist in this world, they rule it; Satan showed Jesus 'All the kingdoms of the world... and said to Him, 'All this authority I will give You, and their glory; for this has been delivered to me, and I give it to whomever I wish' ' (Luke 4:5-6). Jesus refused.
He not only refused, but He won every battle against Satan's army--by resisting temptations and casting out demons from desperate victims. Finally, Jesus won the whole war. He defeated Satan on the cross for every believer. That includes us. Today.
He signed the Ultimate Peace Accord in blood, and then He gave us a gift: the Holy Spirit of God, and all of His power, might, and promise. Can True believers be possessed by evil? Can evil and good co-exist in the same body, the same house?
'And if a house is divided against itself, that house cannot stand' (Mark 3:25). Deliverance ministries seem divided on this question.
Nevertheless Christians 'Put on the armor of God' (Ephesians 6:11), 'Resist the devil' (James 4:7), and even 'Cast out demons' (Matthew 10:8) in the Name of Jesus.
But we must remember our ultimate command is to 'Go into all the world and preach the good news to all creation' (Mark 16:15).
Therein, we bring God directly to the mind, heart, body, and spirit of every sick, possessed, and troubled soul who turns to Him. Demons denied.
