Can a Christian be possessed by demons?
When a person places his or her trust in the Lord Jesus Christ for salvation, there is no possibility of that individual being indwelt by demons. Light and darkness do not dwell together (John 1:5; 1 John 4:4). We cannot be absolutely sure that our problems are caused by Satan, but we do know that he cannot bother us any more than God will allow. God’s power is greater than Satan’s power (2 Corinthians 4:4 and 11–13; Ephesians 6:12 and 16; 1 Peter 5:8-9).
