The short answer to the question “Can Christians be demon possessed?” is, no. The Bible teaches that once we accept Jesus Christ as our Lord and Savior, the Holy Spirit takes residence in us and no other spirit can take its place. In John 4:24, Jesus states, “God is a Spirit: and they that worship him must worship him in spirit and in truth.” Thus, it is impossible for a demon to possess a believer in Christ.
However, although we cannot be demon possessed, we can still be oppressed by demons. Ephesians 6:12 states, “For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.” Demon oppression is different than possession in that the person still has their own will and they are in control of their actions.
If a Christian experiences demonic oppression, there are many ways to fight against it. Prayer is considered to be the foremost weapon against spiritual wickedness, because spiritual warfare can only be won by spiritual means – that is, by relying on the power of the Holy Spirit. Additionally, God’s Word is a mighty source of strength and protection in the face of enemy attacks. Meditating on the promises of God and declaring them out loud has been known to break down the strongholds of the enemy in someone’s life. Lastly, believers can call upon the Name of Jesus whenever they feel oppressed, which will cause the spirit of the enemy to flee from their presence.
In conclusion, the answer to the question “Can Christians be demon possessed?” is no. We may be attacked by the schemes of the enemy, but the power of God is greater and He will protect us at all times.
