We believe in the personal existence of angels (Luke 22:43) and demons (Luke 8:26-39) and Satan who originally was created a holy and perfect being, but through pride and unlawful ambition, rebelled against God (Ezekiel 28:13-17; Isaiah 14:13-14; 1 Timothy 3:7), thus becoming utterly depraved in character (John 8:44), the great adversary of God and His people (Matthew 4:1-11; Revelation 12:10), the leader of all other evil angels and spirits (Matthew 12:24-26, 25:41), the deceiver and god of this present world (Revelation 12:9; 2 Corinthians 4:4), that he was defeated and judged at the Cross, and therefore his final doom is certain (John 12:31-32, 16:11; Revelation 20:10), that we are able to resist and overcome him only in the armor of God and by the blood of the Lamb (Ephesians 6:12-18; Revelation 12:11).
