Angels, principalities & powers
We believe in the personality of angels and that they are a reality. We believe that God created the angels to be His servants and messengers (Nehemiah 9: 6; Psalm 148: 2; Hebrews 1:14). We believe that the personality of Satan and demons exist. Satan is a fallen angel who led a group of angels into rebellion against God (Isaiah 14: 12-17; Ezekiel 28: 12-15). He is the great enemy of God and man, and the demons are his servants in evil. He and his demons will be punished forever in the lake of fire (Matthew 25:41; Revelation 20:10).
Ef. 6:12 "For we wrestle not against blood and flesh, but against the rulers, against the powers, against the rulers of this darkness, against the evil spirits in the heavenly places."
It is not only that God is fighting against the devil, but also the Angels are fighting against demons.
Angels are supernatural, intellectual beings ... Angels, as servants or protectors of man, usually act as messengers of God from whom they are clearly distinguished, and possess superhuman capacities and qualities. “For he will command his angels concerning you, that they may guard you in all your ways; on the hands they will carry you so that you do not bump your foot on a stone. "Psalm 91:11, 12" The Angel of the Lord encamps around those who fear Him and saves them. "Psalm 34: 7,
"Are they not all ministering spirits sent out to serve those who will inherit salvation?" Heb. 1:14
God's Angels are happy that they may serve mankind, they bring light into the darkness and that makes people happy when they are allowed to discover that light.
