They recognize our Lord as the Son of God (Matthew 8:20; Luke 4:41). They belong to the number of those angels that “kept not their first estate,” “unclean spirits,” “fallen angels,” the angels of the devil (Matthew 25:41; Rev. 12:7-9). They are the “principalities and powers” against which we must “wrestle” (Ephesians 6:12).
The word demon(s) does not appear in the King James Bible, which uses the word “devils” instead. The New King James Bible uses the word “demon(s)” in 72 verses.
FEAR OF GOD—Do all demons (devils) fear the one true God? Yes (James 2:19). The Holy Spirit of God is far more powerful than Satan or any demon, and He is the protector of all God’s children (true repentant sinners who believe and follow Christ).
When the time is right, in God’s perfect plan, He will cast Satan and all his devils in an abyss from which there is no escape (Revelation 9:1-12).
NO PHYSICAL FORM—Although good angels are known to sometimes mimic human form in service to God, we know of no occasion in Scripture where a fallen angel (demon/devil) was allowed to appear in physical form. These corrupt spiritual beings are limited by God in what they can do on Earth, less their interference become as overwhelmingly great as they may wish. During the 3 year period immediately before Christ’s Second Coming, we are warned that some will be loosed by God in some ways as a judgment on evil. At the end of this Tribulation period, Satan and all his devils will be cast into a spiritual abyss (bottomless pit) from which they cannot escape.
POSSESSION—Demons may take possession of some sinners outside the protection of God. During the time of Christ’s life on Judea, there were a great many examples of this. Sometimes, multiple demons inhabit a person. Mary Magdalene had 7 demons (Luke 8:2).
EXORCISTS—The only exorcist mentioned in the Old Testament is David (1 Samuel 16:23). In the New Testament, Jesus Christ, his Apostles and the seventy the Lord sent throughout Israel for a time (Luke 10) cast out demons through the power of the Holy Spirit. The deliverance of great numbers of people so afflicted was a clear proof of Jesus’ identity—as the Messiah, the Christ, the Son of God.
