Are there angels? Is the devil real? What are demons?
The Bible teaches that angels, demons, and Satan do exist. Angels are ministering spirits created to serve believers in Jesus Christ, as the writer of Hebrews says:
Angels were created by God, including an angel called Lucifer, who was the greatest of all angels:
Lucifer (Satan) fell into sin because of his pride, and as a result, he brought down a third of the angels with him, as described in Revelation 12:
Notice the dragon (Satan) recruited a third of the angelic realm to join him in rebelling against the Lord. This third of the angelic realm are called demons. Demons are fallen angels, which move between heaven and earth doing the bidding of the enemy. Demons may bring torment to believers and unbelievers, and they may indwell unbelievers as shown in the Gospels.
At the end of this age, demons and Satan are bound and kept in the abyss during the kingdom.
At the end of the 1,000 Kingdom, the enemy is allowed a short time once more to work in the hearts of men on earth. At the end of that time, the Lord will judge Satan and cast him into the Lake of Fire forever.
Rev. 20:10 And the devil who deceived them was thrown into the lake of fire and brimstone, where the beast and the false prophet are also; and they will be tormented day and night forever and ever.
