ANGELS 

A. Holy Angels 
Angels are created beings and are therefore not to be worshipped. Although they are a higher order of creation than man, they are created to serve and worship God. Luke 2:9-14; Hebrews 1:6-7, 14, 2:6-7; Revelation 5:11-14, 19:10, 22:9

B. Fallen Angels
Satan is a created angel and the author of sin. He incurred the judgment of God by rebelling against his Creator. He took numerous angels with him in his fall and he also introduced sin to the human race by his temptation of Eve. Genesis 3:1-15; Isaiah 14:12-17; 

Ezekiel 28:11-19; Matthew 4:1-11; Revelation 12:1-14

Satan is the open and declared enemy of God and therefore of mankind and is the prince of this world. He has been defeated through the death and resurrection of Jesus Christ and he shall be eternally punished in the lake of fire. Isaiah 14:13-14; Ezekiel 28:11-19; 

Matthew 4:1-11; Romans 16:20; Revelation 12:9-10, 20:10
