24 And go, say to the Watchers of heaven, who have sent thee to intercede for them: 'You should intercede for men, and not men for you. Wherefore have ye left the high, holy, and eternal heaven, and lain with women, and defiled yourselves with the daughters of men and taken to yourselves wives, and done like the children of earth, and begotten giants as your sons. 25 And though ye were holy, spiritual, living the eternal life, you have defiled yourselves with the blood of women, and have begotten with the blood of flesh, and, as the children of men, have lusted after flesh and blood as those also do who die and perish.
26 Therefore have I given them wives also that they might impregnate them, and beget children by them, that thus nothing might be wanting to them on earth. 27 But you were formerly spiritual, living the eternal life, and immortal for all generations of the world. And therefore I have not appointed wives for you; for as for the spiritual ones of the heaven, in heaven is their dwelling.
28 And now, the giants, who are produced from the spirits and flesh, shall be called evil spirits upon the earth, and on the earth shall be their dwelling.
29 Evil spirits have proceeded from their bodies; because they are born from men and from the Watchers is their beginning and primal origin; they shall be evil spirits on earth, and evil spirits shall they be called. 30 And the spirits of the giants afflict, oppress, destroy, attack, do battle, and work destruction on the earth, and cause trouble.
They take no food, but nevertheless hunger and thirst, and cause offences. 31 And these spirits shall rise up against the children of men and against the women, because they have proceeded from them. 32 From the days of the slaughter and destruction and death of the giants, from the souls of whose flesh the spirits, having gone forth, shall destroy without incurring judgement, thus shall they destroy until the day of the consummation, the great judgement in which the age shall be consummated, over the Watchers and the godless, yea, shall be wholly consummated.
Even christians can have evil spirits which is where sickness comes from because of sin. Healing thru the gift of healing can only come thru knowledge and understanding of who these spirits are for they are a living being which even Jesus spoke to them. There were times the disciples could not because of
unbelief. Mark 9:19
There were other instances when the disciples were able to cast out demons, but Jesus explains that the demon they encountered in
Mark 9 could only come out by prayer and fasting (
Mark 9:29).
