Demons

Some people question whether demons and spirits exist today, I strongly believe they exist. Jesus accepted without demur belief in the existence of demons, and the Gospel of Mark tells many stories of Jesus casting out demons. From the facts of the Bible concerning demons, they are disembodied spirits-that is, they once had bodies but lost them. This explains why they hunt for bodies. They crave bodies to inhabit.

Demon is derived from the Latin word "daemon", which was derived from the original Greek word "daimon." Daimones or daimonion are the plural forms of the word daimon. A supernatural being that is generally described as a malovent spirit and is frequently depicted as a force that may be conjured and insecurely controlled.

Demons are unclean spirits that can reason. (Matthew 12:43-45)

In Genesis 6:2, demons were fallen angels, formerly of God. It also teaches that they produced a race of beings that were half angelic and half humans called the Nephilim (means giants) and when they were destroyed by the flood (Noah's era), they remained on the earth as demons.

"But now the giants who were born from the union of the spirits and the flesh shall be called evil spirits upon the earth, because their dwelling shall be upon the earth and inside the earth. Evil spirits have come out of their bodies. Because from that day that they were created from the sons of God they became watchers; their first origin is the spiritual foundation. They will become evil upon the earth and shall be called evil spirits. The dwelling of the spiritual beings of heaven is heaven; but the dwelling of the spirits of the earth, which are born upon the earth, is in the earth." (1 Enoch 15:8-10)

It is clear and stated from the book of Enoch that evil spirits are the giants who were born from the union of spirits and flesh.

"When men began to increase in number on the earth and daughters were born to them, the sons of God saw that the daughters of men were beautiful, and they married any of them they chose. Then the Lord said, "My spirits will not contend with man forever, for he is mortal: his days will be a hundred and twenty years."
The Nephilim were on the earth on those days-and also afterward-when the sons of God went to the daughters often and had children by them. They were the heroes of old, men of renown. (Genesis 6:1-4)
